> This code is attempting to short-circuit the hostname->ip resolution on the assumption
that if name starts with a digit, it's already an ip address.  This is of questionable value,
but because it checks for a hex digit, it will fail on names starting with [a-f].  Such names
will not be converted to an ip address, but be returned unchanged.
