Not sure that regex above works all that well as an untainter:)... it allows:

999.000.999.000

as an IP address and look what it does to the legal domain name neonutt.firstpart-secondpart.co.uk

Just for your IP addresses (not for your domain names), maybe something like this regex gets closer to what you need? 


/((\d | [01]?\d\d | 2[0-4]\d | 25[0-5] )\.){3}(\d | [01]?\d\d | 2[0-4]
+\d | 25[0-5] )/

Do people really test for the binary representation of the address too? I haven't seen it that often... but, then again, I dont' get out often.
