Can we suppress fragments for DNS on IPv6? At least the document should mention more about fragments.

It appeared to me that some software on IPV4 behave in weird ways when a hostname has only an AAAA record (and no A). Instead of discarding the hostname from the possible solutions, it keeps it and fail in odd ways because of “unreachability”. I don’t know if this is true with DNS software, but worth to verify.
