While automatic address assignment becomes more important as network size increa- ses, it still can be an important tool even on small networks. It often isn't practical on a small network to install a DHCP server because of server hardware and software costs. Fortunately, with Windows 2000 you can take advantage of automatic address assign- ment without the presence of a DHCP server. Use automatic address assignment Windows 2000 supports Automatic Private IP Addressing, or APIPA. When a Windows 2000 computer that is configured for dynamic addressing boots and can't locate a DHCP server, Windows 2000 automatically assigns an IP address in the range 169.254. n . n with a subnet mask of This means that all computers on the LAN can automatically assign themselves a nonconflicting IP address in the same range, providing connectivity between them. Windows 98 clients also support automatic address assignment through APIPA. Each computer polls the network every five minutes for the presence of a DHCP server, and if one is found, the computer obtains an address lease from the DHCP server in whatever address scope(s) the DHCP server handles. This means you can add a DHCP
