DESCRIPTION
       dns_ip4_packet is a low-level component of dns_ip4, designed to support
       asynchronous DNS lookups. It reads a DNS packet of length len from buf,
       extracts IP addresses from the answer section of the packet, puts the
       addresses into out, and returns 0 or -1 the same way as dns_ip4.
