.SH DESCRIPTION
dns_ip6_packet is a low-level component of dns_ip6, designed to support
asynchronous DNS lookups. It reads a DNS packet of length \fIlen\fR from
\fIbuf\fR, extracts IPv4 and IPv6 addresses from the answer section of
the packet, puts the addresses into \fIout\fR, and returns 0 or -1 the
same way as dns_ip6.
