How is Dynamic DNS Different?

Dynamic DNS works in almost the same manner as DNS resolution to a static IP. Resolution is just a fancy term which means translating a domain name into an IP address so that one computer can find another one on the internet.

The main differences between regular DNS and dynamic DNS are: 1) How often an IP address is updated 2) How the IP is updated 3) And the speed at which the new address is communicated to the rest of the internet. The next section will outline how regular DNS works so you have a basic understanding before we move on to look at these elements of dynamic DNS.
