      So basically the title.

      I've been trying to migrate from a dual-stack to a IPv6-mostly environment and my next set would be to do PREF64 in router advertisements together with DHCP option 108.

        Are you sure that's what you want? Normally, the client device determines that, depending on how it's configured. Also, that PREF64 flag appears to have something to do with NAT64. I have been running IPv6 on my home network for almost 15 years and never had a need to use anything like that. Also, is there a specific reason you're using DHCP6? If not, you're likely better off with SLAAC, as Android devices don't work with DHCP6.

        I haven't lost my mind. It's around here...somewhere...

          I already have a functioning NAT64/DNS64 setup and PREF64 and DHCP option 108 is the next step so that clients that support CLAT will autoconfigure it and become IPv6-only while clients that are not IPv6-aware will continue to function normally.

          I don’t run DHCPv6, the option 108 I mentioned is for DHCPv4 not v6.

            Should be in the next release 2.8/25.03
            I think NAT64 might also come in that release.

            I'm hoping for custom dhcp options in KEA, but the old dhcp is a fallback.

            Then i need to wait for CLAT in Windows, which was talked about in a blog post last year, radio silence sinse then from MS
