This bug is in SuSe, Debian, every version of Red Hat I tested.

Looks like the stub resolver in glibc. Permutation order should be
hostname over AFI, not AFI over hostname, agreed.

So the correct query sequence should be:

- AAAA host.domain.com.
- A host.domain.com.
- AAAA host.
- A host.

That middle query is causing bogus root DNS server traffic every time 
someone sshs to an unqualified hostname within their LAN.

Nod.

SSH people won't take responsibility for this bug.

They are correct. It's not their fault.

The Fedora people won't take responsibility for this bug.

They do, did you test as Florian asked you?
