/* Do IPv6 and IPv4 queries separately then join the result.

* HP-UX only returns IPv6 addresses using SIOCGLIFCONF,
* SIOCGIFCONF has to be used for IPv4 addresses. The result is then
* merged.
*
* Solaris needs particular care, because a SIOCGLIFCONF lookup using
* AF_UNSPEC can fail in a Zone requiring an AF_INET lookup, so we just
* do them separately the same as for HP-UX. See
