Thanks for the pointer to draft-baker-6renum-oss-renumbering, Tim. It’s true that renumbering is only a sequence of numbering actions. On Mar 25, 2015, at 9:20 AM, Mikael Abrahamsson swm...@swm.pp.se wrote: At this time, I do not understand the DHCPv6-PD state machinery to enable temporal

Yup. Are you aware of similar issues with changing the IAID? If the ISP has a limit to how many prefixes can be assigned on a particular customer port, that could cause issues, but if it's a supported feature as it would be in Mikael's case, I think it should be OK. Do you know the
