These dynamic IP addresses are assigned by an ISP. However, many home users are assigned an IP address that changes more frequently. The DNS record for this node will only change infrequently. Most servers on the Internet have a fixed (static) IP address that never changes. a web browser) is then directed to one of these name servers. 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. Name Translation is implemented via a distributed database known as the Domain Name System. Name Translation is the process of relating a name (like '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.
