Abstract
Since RFC3901 from 2004, it is clear that in the DNS IPv4 is a MUST. IPv6, however is a MAY IF YOU FEEL LIKE IT YOU KNOW IF IT VIBES. Since 2023, work was ongoing in the IETF DNSOP working group to change that with a 3901bis document. This document has passed the IESG in February, and is now in the RFC editors queue, bound to be the new Best Current Practice for "doing DNS". This time with IPv6.
In this talk, we will go over what this document now recommends, what operators should do to follow this new recommendation, and also look at some corner case culprits nobody expected to make DNS worse: IPv4 (with a cameo from CGN).
Be ready. IPv6 ready.

Video will be added soon.
