We have the ability to edit the DHCP settings for IPv4 devices in pretty great detail. We can change the lease time, address pool, default gateway, primary and secondary DNS, and even assign static IPv4 addresses.

However, for some reason, the settings for IPv6 DHCP are lacking. In fact, they're so lacking that they don't even exist.

Many power users, such as myself, want/need to be able to edit these settings. There should be no reason why turning off the DHCP server should only affect IPv4 settings, while IPv6 addresses are still handed out like candy to devices that support it. It's especially painful for people who are wanting to set up things such as a Pi-Hole or AdGuard Home instance where you can't point the IPv6 DNS to the server nor can you turn off DHCP to let the server handle it itself. Please consider this as a feature for the next firmware version. IPv6 has been out for a while, there really isn't any reason why these basic features can't exist.
