DHCP
Dynamic Host Configuration Protocol (DHCP) automates the network configuration of computers. It lets a
network with many clients extract configuration information from a single DHCP server. In the case of a
dedicated Internet account, the users are the clients extracting information from the ISP’s DHCP server,
and IP addresses are only assigned to connected accounts.
The account you have with your ISP may use DHCP to allocate IP addresses to you. Account types that
frequently use DHCP are broadband cable and DSL. ISPs may authenticate broadband cable connections
using the MAC address or physical address of your computer or gateway.
