How do I setup a dynamic DNS service?

Setting up a DNS server and forwarding is quite straight forward.

The hard part is how do I get people to come to my server to look things up? If you've ever setup email, you know it is a little more difficult than changing your @hotmail.com address to jsmith@mydomain. While most users would never notice when they forget the password to one of their favorite service, I guarantee you will notice that it is down. How will you let your friends and family know? Even if you use Google App Engine, if your app isn't available for some time it won't be visible in the search results and people will miss it.

What Do I Need to Know? My domain name was jsmith.cloudapp.net and its subdomains. I hosted JGroups there for a few years. This may change for this post (hopefully without changing the end of the article), but we currently are using CloudFlare DNS, Amazon Route53, and SES.

There are many options to choose from. I chose to look at the top 10 providers.

This service is perfect for our needs. The interface is simple to use. There is no real learning curve.

If you setup the first name server in Route53, if you change that you need to point your subdomain names there also. For the most part all the information is readily available. You just get used to jumping into the interface quickly for DNS changes (Route53 interface is much different than the other 9).

If you don't like the new interface you can continue to go through the interface on your local machine or you can change the settings via API calls. You can also use CNAME records so you don't have to add a new record just for @mydomain.

There is no good way to generate reports when dealing with the API. You can request the report by IP address and that works but, not something I would necessarily recommend, since then your report won't have anything more than the requested ip address.

I'm actually working on an easier to use report generator for Route53 that should make your life easier. But, I need your help .

What is the 8.8 8.8 DNS server?

(Part 4)

August 29, 2025. Now we are going to talk about a server called the 8.8 DNS server. If you don't know what this is, it is the 8th IP address in the 8.0/24 network. A computer will always request an IP address from the 8.8 DNS server if it needs an IP address for any request. Here is how it looks like when you access your browser.

You see that number in brackets? It's a record. This server is called a DNS root or a root DNS server. The 8.8 DNS root has a zone. Let's say we want to have some nameservers for example 8.2, 8.10 and 8.11. What will we do? We'll add a records in that zone.

Here is what we can do: nslookup example.com > local-host.txt

Now open local-host.txt with your favorite text editor and write this in there. You need to add 8.11 into that file:

In fact, we'll just enter the entire zone instead of writing each address and zone separately. Let's say we add this: Now this DNS server is used by any computer to access any resource on the Internet. The domain name is stored in the database and that name is given back to you through the root DNS server. In this case, the 8.8 DNS server and this way we have the following:

The computer is asked for an IP address and for a hostname, so that you know how to access the website. Here is a screenshot taken from my computer.

2 8.8 I can easily access all the web resources hosted by Google, Facebook and a million others! I can access every domain name and every webpage using this DNS server. That's why we say that we use the root DNS server. There's no other! That's what makes it the root DNS server!

Does Google have a dynamic DNS service?

When a computer's IP address changes, the change needs to be updated on all machines which have that computer's IP address in their DNS (Domain Name System) configurations. If there is no such service, what are these updates normally done using? For instance, for my office I have to update the IP addresses of every single computer in the office and my ISP's servers in order to have internet access. Is this a service that Google provides? I'm thinking they could provide the same functionality as the regular DNS server for that office. Would it be correct to say "is Google providing this type of service?" I'm looking for answer to be as general as possible, for example "yes". Or else a link to a study that proves that Google does provide such a service.

When a computer's IP address changes, the change needs to be updated on all machines which have that computer's IP address in their DNS (Domain Name System) configurations. There is no requirement for computers to keep DNS settings in sync, and there certainly isn't any requirement that a given machine must maintain its DNS configuration. The only time DNS settings need to be updated is when the IP address for the destination host changes. The DNS service may or may not keep track of that event for you, but the machine that was previously connected to that address is not required to notice that the DNS record has changed.

My ISP's servers in order to have internet access. Your ISPs DNS server may or may not be aware that you have changed your Internet connection. That's going to be dependent upon what you have configured them to do. That's also typically outside of the scope of the DNS and may be controlled by some other system. This is also not related to Google.

What is DDNS vs Dynamic DNS?

Dynamic DNS is like having your own domain name but on the internet. But to get your domain name you need to purchase it from a third party who hosts your domain name for you. The only way you can get the domain name you want is by hosting it. Which usually means you need to pay for some kind of service. There is now also the option to DDNS. If you go into most web browsers these days you will notice a small icon in the address bar of what looks like a phone. You're basically connecting to your website via a VPN and then the host provides a local IP address. This is what DDNS is all about. It's free and simple. When you have any type of issue or issues with your websites and services, you will log into their control panel and enter the details you will get redirected to another site which has their support staff. They offer a lot of add-on features and you can even pay extra to get more. If you don't want to spend too much you can pay by the month. You get an IP address and they are free to use. DDNS is more than just a name. It gives you the privacy of your own IP address so your host doesn't know where you are. You could do your own DDNS service if you want to. They are still free. DDNS is like having a website on the internet but instead of using some company's servers like shared hosting your website uses your own computer. You can use free web hosts. So you can't be tracked by advertisers. DDNS gives you access to all the extra features that companies like to give you, like security, a custom error page and an easy to remember URL address for your site. This is important because it makes it easier for people to find your website. We have put together some tips for you. This includes how to sign up for free. It's easy to do and you can even use a service provider like this for your phone numbers and websites. Make sure your domain name is available to buy at the time. It helps in case something goes wrong. The good thing about this is you can set up your site with a live website address. Your address on the internet. Just like buying a domain name but without the monthly fees.
