In RELENG_9, soon to be released 9.2-R:

=== FILE: wis ===
#!/bin/sh
DEVICE_SELF_SCAN_ALL=
. /usr/share/bsdconfig/media/tcpip.subr
if f_validate_ipaddr6 "$1"; then
	echo "Hey, nice IPv6 addr, great job!"
elif f_validate_ipaddr "$1"; then
	echo "Hey, nice IPv4 addr; smiles"
elif f_validate_hostname "$1"; then
	echo "Hey, nice hostname"
else
	echo "What on Earth wast, _that_?!"
	exit 1
fi
=== END FILE ===

dteske at scribe9.vicor.com ~ $ ./wis 0::1
Hey, nice IPv6 addr, great job!
dteske at scribe9.vicor.com ~ $ ./wis 0:::1
