Dynamic Host Configuration Protocol (DHCP) is used to dynamically assign IP addresses to hosts. Although it is not a true TCP/IP application program, it is important to cover it to some detail.

DHCP uses a client-server structure to provide configuration parameters to hosts. It consists of a protocol that provides host-specific configuration parameters from a DHCP server (or collection of DHCP servers) to a host and a mechanism to allocate network addresses to a host.

The commands in Figure display information about the Dynamic Host Configuration Protocol (DHCP) application. A troubleshooter uses the information from these commands to isolate problems with DHCP.
