It has always been the convention for IPv4 for as long as the dotted notation
existed. In fact it took a while before the full dotted quad notation really
became dominant. For a long time it wasn't clear how large a final segment
would become the most popular with many people using 16-bit network masks.

I'm really skeptical Vixie would have written things this way. Perhaps
somebody at some point later misunderstood the convention and "fixed" the
behaviour?
