@lauren @loke @domi I've run fairly large authoritative dns deployment, I've hacked in the protocol in various ways.
The only concern is if the block allocation is pulled, but this a RIR/LIR concern.
There is nothing in the protocol that would consider this a violation. At the end of the day, this is straight up NS delegation. Is this unusual? yes. Is this humanly possible to remember an ipv6 block allocation? No, not in a large scale, this is the reason for DNS in the first place, but that's it?
