So - just to refocus for a minute...

Australia's largest mobile carrier is currently moving to IPv6 only for mobile handsets with NAT64 at their edges....

Can PD be used for nptv6?

Maybe I'm simplifying a bit too much - but shouldn't this just be a binary on / off and an optional preferred prefix delegation size (normally between a /56 and /64)?

Keep in mind that this bug was originally filed on 2013-12-31 - so I certainly wouldn't hold your breath ;)

With the above change, some 2 years later, are we able to finally use a DHCP PD for IPv6? ie does it actually work?

So in my testing of VyOS - after tinkering with an edgerouter, this is a kinda major feature to be lacking...
