>32-bit int representation of an ipv4 address

Internally, I would imagine that almost every IPv4 stack uses 32bit ints to represent an address. Its not that crazy to think this would leak out somewhere.

I've written (un)parsers where we would just treat IPv4 addresses as integers because A) that is how they were treated in the binary data and B) given what we were doing with the data, we didn't actually care about the IPv4 field.
