These tables show the standard options currrently defined for both DHCPv4 and DHCPv6 and which ones are supported in the ISC DHCP server and Kea DHCP servers.
They may be helpful in planning migration from one server to the other. If there is any doubt, the Kea User Guide includes two tables: supported standard options for DHCPv4 and DHCPv6. The tables below are meant to be a super-set of those.
