So that people can reach your Web site on an intranet or the Internet, you must have a unique IP address that identifies your computer on the network. This address consists of a long string of numbers separated by dots, for example, 172.16.255.255. Because a numeric address is difficult for people to remember, text names, or friendly names, are used to provide visitors with an address that is easy to remember, such as www.microsoft.com. Name resolution involves supplying the correct numerical address from the friendly name that was typed into a client browser.
Name Resolution Systems
Windows networking components rely on the NetBIOS naming convention. In contrast, TCP/IP components rely on a naming convention known as the Domain Name System (DNS). Under Windows, the DNS host name of the server defaults to the same name as the NetBIOS computer name. The mapping of computer names to IP addresses can be accomplished using one of the following two methods:
You can specify which DNS server or servers your server uses to resolve DNS names, or you can configure your server to obtain the address of a DNS server from a DHCP server. For more information, see see DNS Configuration.
