QuestionSomething I just learned, with IP addresses Pin

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:

C#
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:

C#
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...
