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).
