What exactly is DNS?

Let’s start with the basics, the basis of the system. DNS stands for Domain Name Service. It’s like the whitepage directory for the Internet. You supply a name, DNS supplies a number. The name in this case is specifically a hostname and the number is an IP address. Without DNS you would have to remember every IP address of every website you want to visit. With over 300 million websites on the web, remembering every IP address would be utterly impossible, well unless maybe you’re Kim Peek: The Real Rain Man.

What is Dynamic DNS?

Dynamic DNS makes a dynamic IP address act as though it's static (does not change) even though it is not. With No-IP you create an easy to remember hostname. This hostname is the URL that you type into your browser to connect to your remote device. Our Dynamic Update Client takes your hostname that you created (yourname.no-ip.org) and points it to your IP address. When your IP address changes, our Dynamic Update Client updates your IP address on our servers, therefore your hostname stays active with your active IP address and your connection stays available all the time.
