Thanks for all the feedback I also run dual stack with SLAAC for IPv6 assignment and my IPv4 DNS servers resolve the AAAA records.
After skimming through rfc7217 + rfc4941 with the "autoconf temporary" being used for outbound and "autoconf secured" being static and can thus be used for reliable incoming connections I _really_ don't see the use for allocating a 3rd dynamic IP via DHCPv6 that may never be used. For me the use case for DHCPv6 boils down to if you need: PXE boot Provide NTP servers (typically OS handles this even without DHCP) Provide DNS servers (If you don't run dual stack and can't provide DNS servers via Router Advertisement) You need other DHCP options for IP-Phones etc. Dynamic DNS Disclaimer: It's been a decade+ since I did any sort of Enterprise IP management so I'm happy to be corrected if I've missed/misunderstood something. /Roger On Tue, Mar 31, 2020 at 12:18 PM Mark Tinka <[email protected]> wrote: > > > On 31/Mar/20 12:09, [email protected] wrote: > > > Note that there have been multiple requests for DHCPv6 to do this but > > every attempt has been shot down. > > Yep - thankfully, we have an option. > > Operating two address assignment protocols is just silly. > > At my house, I don't even bother with DHCPv6 for DNS.
