Named already has the ability to allow a machine within a /48 to insert/remove a delegation at the /48 point using TCP to authenticate the update request. I wrote the code to support this about the same time as Geoff Huston was looking at setting up 6to4 reverse delegations. He ended up going the HTTP to do it. The code to do that works for any /48 for IPv6 connections. https://tools.ietf.org/html/draft-andrews-dnsop-pd-reverse-02 is a fully fleshed out example of how to do this but I couldn’t get even a request to adopt call from the DNSOP chairs when I presented it. Can we stop leaving this in limbo and move it forward?

I still use the WIDE dhcp6c client for PD and it has no means to update DNS. I haven’t found specific documentation from ISC DHCPv6 or KEA that describes creating DNS entries (PTR records) from delegated prefixes. > > Tom > >> On Aug 24, 2018, at 10:53 PM, Ted Lemon <mellon@fugue.com> wrote: >> >> When would that happen? >> >> On Fri, Aug 24, 2018 at 10:52 PM Mark Andrews <marka@isc.org> wrote: >> Registering slaac derived addresses in the DNS.
