Granted, 0.0.0.0 is technically a valid IP address in some situations, as in dealing with network routes, but for most situations it would be considered as something out of the ordinary, which is why I initially mentioned it. Also, leading zeros, while also technically valid, are also usually not what one would consider a proper IP address.
If you say ping 065.1.01.002, you are probably not going to ping what you think you are pinging. As you rightly said though, this is all a matter of context.:-). You must know your data before trying to implement any solution.
While using a regex for mild IP sanity checking may be ok in some situations,
