Dynamic host configuration

Updated: April 19, 2023

We support DHCP (Dynamic Host Configuration Protocol), which is used to obtain TCP/IP configuration parameters.

Our DHCP client (dhclient) will obtain its configuration parameters from the DHCP server and configure the TCP/IP host for the user. This allows the user to add a host to the network without knowing what parameters (IP address, gateway, etc.) are required for the host. DHCP also allows a system administrator to control how hosts are added to the network. A DHCP server daemon (dhcpd) and relay agent (dhcrelay) are also provided to manage these clients.

For more information, see the entries for dhclient, dhcrelay, and dhcpd in the Utilities Reference.
