Dynamic DNS is a method, protocol, or network service that provides the capability for a networked device, such as a router or computer system using the Internet Protocol Suite, to notify a domain name server to change, in real time (ad-hoc) the active DNS configuration of its configured hostnames, addresses or other information stored in DNS.

Most home users have an IP address that can change hour to hour and this complicates building a home website and making it accessible to everyone on the internet. A DYNAMIC DNS allows users anywhere on the Internet to “find” your website(s) and/or mail server(s) with their constantly
changing IP address. The function of a DNS is to provide a FIXED name for your website to "home to" with a fixed address for remote users on the internet to use to “find” your “Dynamically Changing” IP address. The way this is done is for YOUR remote computers to forward a new IP address to the DDNS (Dynamic Domain Name Server) whenever your assigned (by your local Internet Service Provider) IP address changes.

The DDNS server system can accommodate multiple HOST NAMES for a single website if necessary[/color].
