Dynamic Host Configuration Protocol (DHCP) provides a means of allocating and managing IP addresses dynamically over a network. Before the advent of DHCP, administrators configured each host on a network with an IP address, subnet mask, and default gateway. Maintaining the changes and the logs of the changes took a tremendous amount of time and was prone to error. DHCP uses a client/server model in which the network information is maintained and updated dynamically by the system. | DHCP for Windows 2000 by Neall Alcott Copyright 2001 O Reilly Associates Inc.
