You want a ambigious example? 192.168.222.012 Seen this sort of thing in real life when the admin wanted to make the file look pretty and they wanted 12 for the last octet not 10. Seen boxes that used %03u.%03u.%03u.%03u to print out the octets. It's much easier to just reject octal and hexadecimal than to work out when and when not it is ambigious. It is also better to demand all 4 octets. It also generates less support complaints.
