An obviously fake IP address breaks the suspension of disbelief for those who know what an IP address should look like: four octets of 0-255 each. There's a much smaller population who both knows what an IP address looks like and what IP addresses are assigned and publicly routable. By your logic, IP addresses might as well contain only three dot-separated numbers, such as "350.897.260"... since if there are no degrees of wrongness, why even try to get it minimally authentic looking?
