Dynamic DNS

[Costas]

Every computer attached to the Internet has an IP address. Name Translation is the process of relating a name (like 'www.google.com') to an IP address (like '74.125.19.103') so that a website (or other service) on a computer can be accessed using an easily remembered name, rather than the IP address number of the computer. Name Translation is implemented via a distributed database known as the Domain Name System.
