nua7: That's a useless use of backticks, and also does not actually ping the address.

In fact, you should probably get a reasonable response from ping if the address is invalid.

Code:

vnix$ ping -c 1 999.999.999.999
ping: unknown host 999.999.999.999

There are multiple threads on this site about validating IP addresses; you could look at those, too. Try this canned search:
