Regex valid ip

[eluser]Twisted1919[/eluser]
slowgary , your provided regex is no good at all .
Passing : 192.168.2.299 returns true , but really is ?
or : 0.123.123.123 , is this a real ip ?

On the previus post , i said that i want something more accurate but only from regex .
My pattern does the job pretty good , as it finds that ip like 0.123.123.123 or like 192.168.2.299 is not a real ip BUT i need some minimized version for that regex .
