	KEA is the successor of the isc-dhcp-server.		KEA[https://kb.isc.org/docs/aa-01615] is the successor of the isc-dhcp-server. The [[IPv4]] part works fine. [[IPv6]] appears to be a lot more difficult (like it was for isc-dhcp-server)

	[[IPv6]] addresses can be advertised by the radvd (often on your ISP's router). These are based on the MAC address of the client or pseudo randomly generated. For more control over the addresses you can run a dhcp server. When the [https://www.isc.org/dhcp/ ISC dhcp server] is used you need separate instances for the IPv4 and the IPv6 server.
