Hello,
The current DNS code checks, when making an A query, whether the name
is in fact an IPv4 address literal. Same for AAAA query with IPv6
address literal. This is good.
However, nothing prevents A queries for IPv6 address literals or AAAA
queries for IPv4 address literals. This is wrong.

Attached is a simple patch to fix the bug (of which there are three
distinct instances).
Comments?
