|  |  | Dynamic Host Configuration Protocol (DHCP) allows DHCP-enabled clients to move from one network to another without reconfiguring their TCP/IP stacks. When a client boots the network, DHCP broadcasts a request for the network's IP address. The Cisco DHCP server then assigns the node an IP address and provides addresses of both the DNS server and the default gateway. The DHCP server stores the client's unique hardware address in its database to track the machine's IP address.
