Whether you’re hosting a web page or running a Minecraft server, it’s a pain to keep track of IP addresses. Using a free dynamic DNS, you can turn 188.8.131.52 into mygeekydns.dyndns.org and be free from changing IPs.
Dynamic Domain Name System services can be found in many places online for varying costs, but they all work more or less the same way. We’ve talked about DNS before – mainly when mentioning OpenDNS, Google’s Public DNS, and NameBench – but, essentially, DNS servers are like address books which convert IP addresses into host names. As you can imagine, this makes the web much easier to work with.
Getting your hands on a .com can be tough and expensive, but if you have your own server you can sign up with a dynamic DNS service. Signing up will get you a simple hostname, and by configuring your router, your ISP-assigned ever-changing IP will be updated automatically. No more looking up and writing down IPs!
There are a few different DDNS services out there, such as FreeDNS and No-IP Free, but we’re going to focus our article on DynDNS. Why? Well, it’s one of the more popular services, they have really great uptime and support, and I’ve never had to mess with it in the 6 years that I’ve been using it. They all more or less work the same, though, so if you decide to go with another provider, you should still be able to follow along or figure things out.
