Re^2: Don't Use Regular Expressions To Parse IP Addresses!

Not really - the above regex is wrong. Try it on 10.76.110.219 and it will match only 10.76.110.21 (since 1?\d\d? will match 21 and stop and not look for the 2[0-4]\d rule)

It works inside the correct context. For example, if you supply a leading ^ and trailing $ then all is well. You have to supply your own context.	[reply]
