DHCP¶

Dynamic Host Configuration Protocol (DHCP), allows a device such as pfSense® software to dynamically allocate IP addresses to clients from predefined pools of addresses. DHCP also sends configuration information to clients such as a gateway, DNS servers, domain name, and other useful settings.

There are currently two available DHCP backends: Kea DHCP and ISC DHCP. Kea is more modern and well-supported, but not fully implemented yet. ISC DHCP is deprecated but contains functionality not yet implemented in Kea. The backend can be changed under System > Advanced, Networking tab (Server Backend).
