I noticed the other week that this `feature' is specifically
disallowed by rfc2553:

   If the af argument is AF_INET, the function accepts a string in the
   standard IPv4 dotted-decimal form:

      ddd.ddd.ddd.ddd

   where ddd is a one to three digit decimal number between 0 and 255.
   Note that many implementations of the existing inet_addr() and
   inet_aton() functions accept nonstandard input: octal numbers,
   hexadecimal numbers, and fewer than four numbers. inet_pton() does
   not accept these formats.
