Definition: DHCP allows a computer to join an IP-based network without
having a pre-configured IP address. DHCP is a protocol that assigns unique IP
addresses to devices, then releases and renews these addresses as devices leave
and re-join the network.
Internet Service Providers (ISPs) usually use DHCP to allow
customers to join the Internet with minimum effort. Likewise, home network
equipment like broadband routers
offers DHCP support for added convenience in joining home computers to the LAN.
DHCP environments require a
DHCP server set up with the appropriate configuration parameters for the
given network. Key DHCP parameters include the range or "pool" of
available IP addresses, the correct subnet masks, plus gateway and name server addresses.
Devices running DHCP client
software can then automatically retrieve these settings from DHCP servers as
needed. Using DHCP on a network means system administrators do not need to
configure these parameters individually for each client device.
