Description Sir Raorn 2009-11-06 18:54:13 MSK 
0.0.0.0 should be treated as valid IP address since it is possible to run service on this IP (which means "all interfaces and addresses") and connect to this address (using http://0.0.0.0:3000/ for local Rails applications works too).

Another issue, addresses like A.B.C.0 CAN be valid if netmask (which is not taken in account in this checks) is greater than /24.

Function and regular expressions make only what is described in the commentary in the source text. You want real ip calculator?
