Applied.

NAKed on the grounds that it seems to be a featuritis.

We seem to already have it:   host2sockaddr("host[:port]", port_no)
and   host_and_af2sockaddr("host[:port]", port_no, AF_INET[6])
in case you need to restrict yourself to a single AF.

Most applets already use those and as a result, are IPv6 enabled.

Those which still use gethostbyname are still IPv4 limited:
mount: uses crazy libc RPC code.
hostname: perhaps can be converted?

Use gethostbyname indirectly: route, arp.
They do it in somewhat convoluted manner, making conversion hard.
