What is Dynamic DNS and why do I need it?
DNS (Domain Name Server) is how the internet maps human style domain names (like google.com) to ip addresses. In the world of internet there are two types of IP address, static and dynamic. Static IP addresses don’t change, so it’s relatively easy to map domain names to the correct IP addresses. Dynamic IP addresses, on the other hand change from time to time. Most cable modem and DSL services provide dynamic IPs. That means that if you want host a file server on your home computer, or be able to access your files from work (or while on vacation), you’ll need some way to keep your IP address up to date in case your provider changes it.
This is the purpose (or one purpose) of Dynamic DNS providers such as dyndns.org or no-ip.com. You sign up for an account, choose a host/domain that you think you’ll remember, and then run a program on your computer or router that tells the service your current IP address. That way, no matter where you are me.ddns.net (or whatever you chose) will always point to your computer.
The problem is that DynDNS discontinued their free service and I could never seem to remember my No-IP hostname. Moreover, for a free account, in No-IP, you have to log in every month and tell them not to discontinue your service. Not too cumbersome, but still, can’t they just check user logs and only require that of dormant accounts?
So where do I get Dynamic DNS for free?
I thought there had to be a better way, enter Namecheap.com. In my Upgrade from Shared Hosting series, I suggested some benefits of separating your domain name registrar from your webhosting. I also suggested that you could even separate your DNS hosting from your Domain Name registrar. Namecheap.com happens to offer fairly competitive domain registration. They also offer free DNS hosting, so no matter, who you use as your domain registrar (even if it’s your webhost), you can still use Namecheap.com as your DNS host.
I did not know it until recently, but one of the features that Namecheap.com offers as part of their free DNS hosting is free Dynamic DNS. It is insanely easy to set up, and the best part is that the routers that I use have Namecheap.com already configured as a Dynamic DNS provider (meaning that you don’t have to run a program on your computer).
Describe this “easy” process
This only works if you’re using Namecheap as your DNS server. For this article, I’m assuming you already have it or have followed my directions here.
- Log in to Namecheap and choose “Your Domains/Products”. Then scroll down to “Free DNS” and choose Hosted Domains.
- Click on the domain name you want to use for Dynamic DNS.
- Choose a “host” for your dynamic DNS. So, if you want me.mydomain.com to go to your home computer, create an A record for “me” with a short TTL (time to live) and give it the ip address 127.0.0.1. (it doesn’t really matter, because it will be overwritten by your update client). Choose save changes.
- On the left hand side, under Advanced Options, choose Dynamic DNS.
- Choose enable, and then look at the directions. If you’re following me, you can ignore everything except the password. Copy down the password, and open a new browser window.
- Enter the Following URL into the Browser: https://dynamicdns.park-your-domain.com/update?host=[host_name]&domain=[domain.com]&password=[domain_password]/li>
- The [host_name] is the host you created the A record for above. The [domain.com] is your domain name. The [domain_password] is the ppassword you copied a second ago. So using my example above, the address would read https://dynamicdns.park-your-domain.com/update?host=me&domain=mydomain.com]&password=efg3234ksdfj234jfsdlk3/
- Hit enter and you’re done. Visiting that web address copies your current IP address into the A record you created in the first step. Now me.mydomain.com will point to the computer you used to enter the address above.
- You can read the official help files from Namecheap.com here.
Maintaining your Dynamic DNS
You need to have some way of updating your IP address. You could just bookmark the web address above and visit it once a day or once a week, but that’s not very automated or cool. You could set up a cron job to wget the address once a day (if you’re using Linux or Mac). Or you could install a DNS updater. But the easiest way is to configure your browser to do it for you.
The official Namecheap.com Dynamic DNS help files have directions for setting up a DD-WRT router. On my Asus router, after logging in, I went to WAN under Advanced settings (left hand side) and then chose DDNS from the options across the top of the page. Choose Namecheap from the server dropdown, and enter your information (host, domain name, password), hit save, and you’re done.
Free, simple, no brains Dynamic DNS. And the best part is you get to your own domain name instead of whatever leftovers DynDNS or No-IP happen to have available. Even if you don’t have a domain name, buying a domain from Namecheap (or other registrar) will cost you less than DynDNS’ least expensive option.

Major Update
Although Google seems to be determined to hide it, you can migrate much of your existing account using the methods documented here. For example:
- Log in to google with the account you want to transfer data from.
- Now go to this link. You’ll need to change the e-mail addresses to match your source and destination accounts.
https://www.google.com/dashboard/migration/?srcAccount=source@gmail.com&dstAccount=detination@yourdomain.com
- Choose the accounts that you want to transfer (it is irreversible) and hit go. This works for youtube, picasa, and groups, but most significantly not google play.
- Moving e-mail, contacts, and calendars is pretty easy, so I’m not covering it here.
Considering Google Apps
The decision to use Google Apps as an e-mail provider is a big one, because you’re getting much more than an e-mail provider. The ramifications can be extremely annoying. First, we’ll deal with reasons to use Google Apps:
- Great spam filtering
- Top notch network and redundancy. If Google’s network fails, the world ends (or something like that).
- Good web user interface
- POP3 and IMAP compliant
- Shareable calendars
- Integrates well with Android. Works natively with iPhone
- Generous storage space
- Free for up to ten “users”
- Access to other Google Apps services
- Customizable landing pages and urls, e.g. mail.yourdomain.com
Downsides:
- Concerns over privacy and use of your data to target marketing to you.
- Practically impossible to reconcile personal Google accounts with Google Apps account.
- Organization approach is not conducive to a single person with a domain name for a personal site/e-mail/blog.
- Confusing login pages.
- No traditional e-mail aliases.
That doesn’t sound like much of a downside, but the second one is HUGE!!!!!!!!.
If you already have a Google account for services like Picasa, Youtube, and Play store, you will find it practically impossible to migrate your data to the new account. If you have an Android, you will not be able to transfer your app purchases to your new account. This means that you will have to sync at least two accounts on your phone. Moreover, you’ll have to decide which account you want to put new purchases on. If you want your Youtube channel to be under your own domain name instead of your original account, you basically have to re-upload every single video. And if you have a popular channel or a lot of comments, you lose all of that history. If you have a lot of contacts in Google+, huge pain there too (although I can’t imagine anyone actually using Google+.)
Google Apps users have been complaining about these issues for more than five years with very little progress in resolving them. Part of the problem stems from the assumption that only “organizations” will use Google Apps. The whole thing is geared toward businesses that need e-mail, calendars, and a word processor/spreadsheet. Google seems completely oblivious to the idea that there are people who own their own domain name and just want to move their existing Google accounts over to Google Apps. I mean, really, unless I divorce myself or fire myself, I’m never going to leave the patheyman.com organization. And if I do decide that I like heymanator.com better, then I don’t want to have to create a new heymanator Google Apps account. I want to simply transfer my account from one domain to another.
An additional problem is the Google sign on pages. To log in to Google Apps, you have to go to google.com/a/yourdomain.com. Then you set up a user, you@yourdomain.com. You log in to Google Apps and play around. When you log out, you’ll be taken to a generic Google log in page. If you try to log in to with your e-mail address and password, instead of logging in to Google Apps, it will create a personal account with that e-mail and then tell you that you have a conflicting accounts because you have a Google Apps account and a personal Google account with the same e-mail address. I don’t know what idiot at Google thought this was a good idea, but it’s the stupidest thing in the whole world!
While we’re talking about sign on pages, you can also “customize” the sign on page and apps with your own logo and colors, but the image size can be no bigger than 143×59 pixels, and they’ll stretch it if it’s smaller. It’s just silly. Moreover, the main account sign on page is not customized—only the gmail, calendar, contacts, and documents apps are customized. Seriously, Google. You need to hire me to tell you how to run this aspect of your business.
Google Apps does not let you create traditional e-mail aliases. Instead they suggest that you add a dot or plus to your e-mail address, because me+dumboffer@yourdomain.com will go to me@yourdomain.com. Stupid, right? Especially if you’ve already got all your bills going to banking@yourdomain.com. A much better workaround is to create a “user” (account) and then tell Google Apps to send all e-mail that does not belong to an actual account to that e-mail. You can use e-mail forwarding rules to send the mail to the appropriate person. Of course, even here, Google apps has to be stupid. It makes you confirm the ability to forward e-mail to your own domain when you only have up to ten users in the first place.
I know the stupidity at work in Google Apps, but I want to use them as my e-mail provider anyway.
Okay, but I warned you. The first thing to do is open your Google Apps account. If you have 10 or fewer “users” (accounts) then the Standard (free) edition should work just fine for you. The problem is that Google likes to hide it. There is no direct link to it, and most of the guides from a year or more ago are outdated. As of October 3, 2012, the way to get to the Standard (Free) Google Apps is to go to the Google Apps page and then click the pricing link at the top. You’ll see the Standard, Business, and Premier plans, with Standard being free…YAY!!!!!
Fill out the boxes with the appropriate information, and then you will have to prove that you own the domain that you are registering for. The easy way to do this is to upload a file to your website.
- Download the file
- Upload the file to your webserver
- Tell it that you did it.
Now you get to choose between Express Setup and Custom Setup. I chose Custom setup which is a huge pain in the—well—something. If you’re setting this up for just yourself or you and your wife and kid, I’d say choose the Express setup. I can’t really describe it too much, because I didn’t do it, but hey, there you go.
Tip: Throughout the set up process, keep an eye on the top center of the screen when you hit save or submit changes. Status messages will flash up there. If you get an error message, it will flash red just long enough to see that there was an error, and not quite long enough to read it, so pay attention.
As part of the set up process, you’ll need to set up one or more e-mail addresses (users). Here’s where the dashboard will lead you astray. It implies that the set up process has four steps, with the last step being “Direct email to Google Apps Mail.” You would think that this would walk you through changing your DNS settings, but you’d be wrong. It actually takes you to a screen on how to set up your mobile device with your Google Apps account.
The real fourth step is to set your DNS records so that the MX records are pointing to Google’s e-mail servers.
- Log in to your DNS host.
- Change your TTL (time to live) on your mx records to 300 seconds (5 minutes). If you screw up, it will only take 5 minutes for changes to take effect.
- Change your mx records to point to Google’s servers. Namecheap.com is particularly nice in this regard, because they have an option “Google Apps” that will automagically configure your mx records correctly. If your DNS host does not provide this useful service, then you should enter the following:
Hostname |
Target |
Type |
Priority |
TTL |
@ |
ASPMX.L.GOOGLE.com |
MX |
1 |
300 |
@ |
ALT1.ASPMX.L.GOOGLE.com |
MX |
5 |
300 |
@ |
ALT2.ASPMX.L.GOOGLE.com |
MX |
5 |
300 |
@ |
ASPMX2.GOOGLEMAIL.com |
MX |
10 |
300 |
@ |
ASPMX3.GOOGLEMAIL.com |
MX |
10 |
300 |
- Once your DNS records have propagated, you can set the TTL back to whatever it was before.
- You can now access your e-mail by going to mail.google.com/a/yourdomain.com, but you probably would prefer to go to mail.yourdomain.com. You can customize your mail, calendar, contacts, and documents (GoogleDocs) in the same way.
- Log in to your Google Apps dashboard and in the center of the screen under “Your Google Apps” click on the settings link to gmail.
- Under web address, click change link, and choose the url you want to use, such as mail.domain.com, and click continue.
- It will direct you to create a CNAME pointing mail to ghs.googlehosted.com. (some DNS hosts require the ending period for CNAMES)
- Then click done. Now rinse and repeat for calendar, contacts, and documents.
- Now you just need to set up your mail clients and mobile devices to check Google’s servers instead of your own.
Note: Google has pretty extensive help online, but it’s organized in an obtuse way that makes finding what you need almost impossible. They also have help records for specific DNS hosts, but in the case of NameCheap.com, they didn’t mention the automagic way of doing it.

Google’s directions for setting up custom urls for mail, et al with a fancy video and everything.
Unfortunately, I have not been able to figure out how to set up a custom URL for the main login page—only the individual apps mentioned above.
Now enjoy and regret the fruits of your labor. I had been getting 200+ spam messages a day despite training spam filters, and now I get less than five.

- Setting up a Linux VPS
- Making the move
by Pat Heyman | Oct 3, 2012 | Essays, Pat
The essential steps in moving are:
- Move your domain name to an alternative registrar (if your web host registered your domain name for you.
- Move your nameservers/Edit your DNS as appropriate
- Consider your e-mail provider
- Choose a new account
- Set up the account and migrate data
- Test the site
- Point your DNS records to your new account
- Cancel your old account
This article will deal with steps 1 – 3.
Move your domain name to an alternative registrar
If your domain is registered by your web host, transfer it to a Registrar. There are several very inexpensive companies to choose from, and transferring extends your domain’s subscription for a year with most registrars.
All registrars ultimately send your information to ICANN. It costs them about $6.50/year to do so…so you should expect to pay at least that much. Many registrar’s make most of their money by upselling you on other services, such as private registration and webhosting (just say no to web hosting).
The basic steps are:
- Find out from your web host how log in to their domain management module.
- Once logged in, make sure that your domain is not locked.
- If it is locked, you will need to request an EPP code, which will be sent to the e-mail on file. (This is designed to prevent someone from hacking your password and stealing your domain name.
- Create an account on your new registrar, and provide them with your EPP code.
- Done
One thing to be aware of is that some registrars also provide DNS services which will help to simplify the next step, but is certainly not necessary.
Some registrars that have gotten multiple positive reviews on webhostingtalk.com are listed below. This is neither a recommendation nor a complete list—just a convenience listing. Like the phone company, some companies hide fees in their quotes to make them appear lower.
- namecheap.com (includes DNS services)
- namesilo.com
- netearthone.com
- dynadot.com
- moniker.com
Here are some registrars that are recommended against:
- Godaddy (unreliable as of late)
- Network Solutions (expensive)
- Your current or future webhost
DNS Hosting
When/if you changed Registrars whatever name servers you were using were automatically put into the new registrar. If you are currently using your web host’s name servers, I recommend using alternative name servers (DNS hosting). DNS stands for Domain Name Server, and works like a phone directory for the internet.
When you type a website into your web browser, the request is directed to a DNS (name server). The name server tells your browser what IP address to go to. Most websites have multiple name servers in different geographical regions so that if the first one fails, the second (and third, etc.) act as a back up. You can host your own name servers, but unless you have multiple VPS or dedicated servers throughout the country, you’re better off using a DNS hosting service.
The directions below should work for most simple websites. If your needs are more complicated, then it should at least point you in the right direction.
Before we begin, there are some definitions we need to cover:
- A record: These are the “main records” and are directed at an IP address.
- CNAME: These can be thought of as a redirect to a website (or other server). For example, www is usually a CNAME that redirects back to your domain so that domain.com and www.domain.com will both go to the same place.
- MX: The MX record is the mail record that tells mail servers where to direct e-mail sent to your domain. Ideally you should have several mx records with multiple mail servers.
- Redirects: allow you to redirect a server name to almost anywhere. For example, you could point support.domain.com to www.domain.com/support/contact.html. A records and CNAMEs cannot point to a website folder or page—only servers.
- TTL: Time to Live. Your name servers are communicated to other name servers throughout the internet, and they are all sharing their records with one another. The TTL tells the other servers how long they should wait before refreshing the information. The TTL is set in seconds.
Setting up your DNS hosting
- Find out what your current DNS records are.
- Create an account with a DNS hosting service if your domain registrar does not provide it.
- Re-create your DNS records in the new DNS host
- Double check your DNS entries.
- Change the name servers listed by your domain registrar to your new DNS host.
- Test and make sure they work.
Choosing a DNS host
There are many reliable DNS hosts and many domain registrars provide free DNS services to customers. Namecheap.com even provides them for free to non-customers. Most of the free DNS hosts have a limit on the number of domains they will host. Some host as few as 1 for free, while others will host as many as 50.
Some free hosts that have received good feedback on webhostingtalk are listed below. Same caveats as with the registrars above.
- Namecheap.com
- clouddns.com
- pointhq.com
- Lowendbox.com has a page with a list of more free DNS hosts
Testing your new DNS:
Once you change your name servers with your registrar, you will need to wait a little while for the changes to “propagate” throughout the internet. It’s like a rumor spreading through a crowd. It can supposedly take as long as 48 hours to fully propagate, although I have noticed that changes begin to be reflected within 5-15 minutes and within a two hours, it seemed like for all practical purposes, they were propagated enough.
So with the above in mind, be aware that different testing services may have different results based on how propagated your nameservers have become. And even then, sometimes one DNS testing service comes up with weird errors when the others are reporting just fine. So if you’re receiving e-mail, and you can visit your websites, and there are no security issues, I wouldn’t worry too much about one weird DNS report.
The following sites provide free DNS testing:
- intodns.com
- dnssy.com
- thednsreport.com
- dnscolos.com
Choosing a mail server
The next step in preparing for a move is choosing an e-mail provider. There are basically four choices:
- Use your web host provided mail server (usually only for shared hosting and managed accounts).
- Administer your own mail server. Not recommended for newbies. Yes, it can be simple to set up with tutorials and scripts, but learning how to manage and secure it as well as deal with spam is not simple. Moreover, running your own mail server may decrease the performance of your
- A third party mail service. There are free and paid e-mail services. List of known free services here.
- Google Apps: Yes, I know this belongs to number 3, but it’s really deserves it’s own section, because the choice to use it is so complicated. I’ll cover it in some detail in the next installment.
I would personally recommend going with either option 1, 3, or 4 unless you really know what you’re doing. If you go with option 1, there’s nothing you need to do at this point. If you go with option 3 or 4, you’ll need to create your account and then point your mx DNS records to the mail servers they provide you with. I’ll cover how to do this with Google Apps in some detail in the next installment.
At this point you are completely mobile. It should be a smooth transition to whatever web host you choose.

These best practices apply no matter whether you keep your current account, upgrade your shared account, or move to a VPS or Dedicated Server. (Many of these were gleaned from readings on webhostingtalk.com and lowendbox.com.)
Pay Monthly
It can be very attractive to pay annually or even prepay several years in advance because hosting companies often provide deep discounts or “freebies” such as a free domain registration. This can be a mistake for a number of reasons:
- You may be happy with your host now, but service or performance may deteriorate over time
- The company may go bankrupt taking your prepaid money with it.
- The company may be bought out, and you may not like the new management.
Make your own automated backups
Many web hosts make tout their automated back ups, but relying solely on them is not a good idea unless you like Russian Roulette. See points 2 and 3 above.
Use a host that allows shell access
Even if you use a shared account, you should still choose a host that allows shell access. This greatly facilitates making your own automated back ups.
Do not register your domain with your webhost…even if they offer free registration
It is slightly less convenient, but it tremendously adds to your mobility. If you leave web hosts, but your host registered your domain, it adds another barrier to leaving. If there is a dispute with your host, or if your host goes out of business, you still have access to your domain name, and since you made your own back ups it’s fairly easy to get back up and running without losing too much in time or content.
I’ll go over the steps in how to do this in the next installment.
Consider an alternative DNS host (nameservers)
Some web hosts, such as Lunar Pages, make it very difficult to customize your DNS records. Managing your own is slightly more complicated, but it is vastly more flexible.
I’ll go over how to do this in the next installment.

It’s pretty inexpensive and easy to set up a website these days. Companies like Hostgator and Dreamhost have you search for a domain name, fill out a couple forms, enter a credit card and congratulations. You now have a website. After a while, you may feel that your needs have outgrown your account, or that the service is not up to par or that your website is too slow. It’s obviously time for an upgrade, but from what to what?
From What?
Chances are you originally signed up for what is known as “Shared Hosting”. On a shared account, you share the server (computer hardware) with up to several thousand other users. If you get lucky, most of the websites are barely used at all, and your performance is decent. If you are unlucky, you may share the server with several other high traffic websites, which may impact the speed of your own site. Additionally, you share an e-mail server with several thousand other accounts, so if one account is flagged as a spammer, it may prevent you from sending any e-mail at all to some domains.
To What?
You essentially have three choices. You can upgrade to:
- a bigger shared hosting account and hope you have better luck. Sometimes these will be called premier or business plans.
- a Virtual Private Server (VPS).
- a Dedicated Server.
Shared Hosting
If you don’t need the additional bandwidth or storage space of the premium shared host, then you are really just paying for a fancy name most of the time. You are not really paying increased performance. But what about “unlimited plans”? To quote the T-Mobile Commercial, they’re more like Um…Limited plans. They’re just hoping you’ll be lured by the word unlimited but not take them seriously. If you do take them at their word, you may find that you account is suspended.
If you do opt for a shared hosting plan, you should get a “metered” account that has an allotment of a specific amount of hard drive space and bandwidth. Companies with such plans are generally less likely to oversell their servers.
VPS
A VPS is similar to a shared account in that multiple accounts are on the same server (computer), but in this case, the server is divided into several virtual machines. You have complete control over your virtual machine, so that you may customize it however (mostly) you like. VPS’s can be used to host website, e-mail servers, ventrilo (online gaming chat) servers, and even Minecraft.
There are two basic types of VPS—mananged and unmanaged. Managed accounts are very similar to shared accounts in that the webhost company takes care of most of the chores of managing the server, but you pay for the privilege; usually $25 or more per month compared to a comparable unmanaged account. In an unmanaged VPS account, you are solely responsible for installing and maintaining your server. The webhost will install a barebones operating system, and you will get to do everything else. The benefit is more control and a deep discount.
In a VPS, whether managed or unmanaged, you will also get to choose your operating system, usually Windows or Linux. Typically Linux accounts are much cheaper than comparable Windows accounts.
Accounts are usually priced based on the amount of disk space you are allotted and the amount of memory you can use. VPS servers can be oversold, so it’s a good idea to test your new VPS quite heavily while you are still in the money back guarantee period. It’s also a good idea (no matter what kind of plan you have) to pay month by month rather than yearly.
There are several virtualization methods available, such as OpenVZ, KVM, Xen, and “Cloud”. OpenVZ often gets a bad rap as being “easy” to oversell, but in reality, any VPS can be oversold, so choosing a reputable company and testing your VPS is still the best way to go. In many cases, upgrading your shared account or going with a better company may be a better option than VPS.
Dedicated Server
Dedicated servers are similar to VPS in how they run (managed or unmanaged) but instead of sharing a computer with other users, you get the whole computer to yourself. Dedicated servers are generally much more expensive than VPS. Personally, I think that unless you are making enough money to justify the cost of a dedicated server, you are better off going VPS (or even shared).
Bottom line
- Know why you want to move webhosts. You are more likely to choose a more suitable webhost.
- Balance your needs with you budget. Do you have thousands of active members in a forum or are you running a blog that not even your mother reads? Do you have half a dozen websites that you maintain? Are you making money off your website? How vital is it that your website not go down?
- How adventuresome are you in terms of learning new things? How much hand holding do you need?
- Check your current website’s statistics and see how much disk space you are using and how much bandwidth you used each month in the last year.
- Ask yourself if you could save disk space and bandwidth by moving video files to Youtube or Vimeo
- Do some research on a forum like LowEndTalk or Web Hosting Talk to find a reputable company.
- Pay monthly so it is easy to walk away if you are unhappy.
- Make a back up.
