QuestionSomething I just learned, with IP addresses PinmemberTimothy CIAN20-Jan-12 6:42 
So here I was, trying to figure out why I was having problems with my ASP RegEx validator control. The objective was to match to an IP address, but to allow it to end in "*" in the final octets (that is, 255.255.255.255 is valid, and so is 255.255.255.* or 255.255.*.* or 255.*.*.*).
 
But the validation was failing for 0.0.0.200, or anything over 199 in the last octet.
 
Here is what I had:
 
ValidationExpression="((1?\d?\d)|(2[0-4]\d)|(25[0-5]))\.(([*]\.[*]\.[*])|(((1?\d?\d)|(2[0-4]\d)|(25[0-5]))\.(([*]\.[*])|(((1?\d?\d)|(2[0-4]\d)|(25[0-5]))\.([*]|((1?\d?\d)|(2[0-4]\d)|(25[0-5])))))))"
 
Here is the fix:
 
ValidationExpression="((25[0-5])|(2[0-4]\d)|(1?\d?\d))\.(([*]\.[*]\.[*])|(((25[0-5])|(2[0-4]\d)|(1?\d?\d))\.(([*]\.[*])|(((25[0-5])|(2[0-4]\d)|(1?\d?\d))\.([*]|((25[0-5])|(2[0-4]\d)|(1?\d?\d)))))))"
 
By reversing the order (priority) of the octet matches, I solved the problem...
