Determine about the Address Translation
When a Web site address or URL is typed in the Web browser, as www.bbc.com and not as a series of numbers, it is essential for the server to know where exactly the data has to be sent to or received from. This address is mapped on to (or translated into) a series of numbers. The translation is called "domain name resolving", "Host name resolving" or "name server lookup". For instance, the VSNL site address www.vsnl.net.in would translate to a group of four octets like 202.30.15.30. The translation is done on the whole name and not on each byte between the periods. The task of number translation is done solely by a domain name server (DNS) on the Intranet server. Like all devices, it has its own IP address (e.g., 194.62.15.20).
