I think that is because not every IPv4 adress has the format x.x.x.x There are short forms (i.e. 1.1 that gets expanded to 1.0.0.1, though not sure if that's in the original RFC) or decimal forms. And then there's IPv6, which again has its rules.

Huh, I thought omissions/abbreviations of addresses was introduced with IPv6.
