+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.

+This database is implemented on the Internet by DNS name servers which keep track of DNS records and exchange this information between each other to maintain consistency. Every request for a name (ie. a web browser) is then directed to one of these name servers.
+Most servers on the Internet have a fixed (static) IP address that never changes. The DNS record for this node will only change infrequently.
+However, many home users are assigned an IP address that changes more frequently. These dynamic IP addresses are assigned by an ISP. This makes it a challenge to translate a Name to one of these IP addresses.
+A number of DNS name servers offer a method to update the DNS database with dynamic IP name translations. This is accomplished by using a small software utility on their computer or a local router.
+These Dynamic DNS services allow the user to choose a hostname and set an initial IP address to correspond to that hostname. The software utility then periodically checks for a change to the computer's IP address, and when a new IP address is discovered, it updates the Dynamic DNS database to reflect that change.
