Post #2358495

@Oskar456@mastodon.social @phils@chaos.social RFC3901bis is clear NOT to put IPv4-mapped IPv6 addresses into AAAA records for this reason. Full current text is: > To maintain name space continuity, every DNS zone MUST be served by at least two authoritative DNS servers providing services via IPv6. To avoid reachability issues, authoritative DNS servers MUST NOT use IPv4-embedded addresses [RFC6052] (including IPv4-Mapped IPv6 addresses and deprecated IPv4-Compatible addresses [RFC4291]) for receiving queries. Furthermore, the delegation configuration of an NS (Resolution of the parent, resolution of sibling domain names, glue) MUST NOT rely on IPv4 connectivity being available.
