I don't think that will work. If you truncate the address we'll lose uniqueness.

It needs to be a ipv4 address or nothing, since that is the only thing that fits in 4 bytes.

MAC and IPv6 address is useless for this algorithm since they are too big.

If we can't get an ipv4 address we should just use a random.
