The man page lies.  There is no way to tell using
those functions whether you have parsed a valid
address.

::ffff:192.168.0.1 is *not* an IPv4 address, syntactically.
IPv4 addresses don't have colons and hexadecimal in them.

It may be an IPv6 address that is semantically equivalent
to an IPv4 address, but parseip is just a poor little parser.
