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.

<br>
However, nothing prevents A queries for IPv6 address literals or
AAAA queries for IPv4 address literals. This is wrong.

Here's the bug in action (anonymized to protect the innocent):

<blockquote type="cite">1.2.3.4 -> 5.6.7.8 SIP 830 Request: ACK
<a class="moz-txt-link-freetext" href="sip:foobar@9.10.11.12:5060;transport=udp">sip:foobar@9.10.11.12:5060;transport=udp</a>
<br>
5.6.7.8 -> 1.2.3.4 DNS 72 Standard query AAAA 9.10.11.12

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