Most Concise RegExp for matching Decimal IPs. If nothing else, it'll make your code easier to read. (And I know that \d?\d is \d{1,2} but that's 2 extra characters.) --Update: darkone noticed 8 characters could be shaved down. I've edited it to reflect this. Thanks, darkone!

This expression checks the validity of a date (US, but it is easily editable for other format's). Year's 1990-9999, Month's 1 or 01 to 12, Day's 1 or 01 to 31. Still needs to have individual months added (i.e., Feb's 28 days), and some how to check for leap year...the months issue should not be to hard, but the leap year seems like a real chore. Please let me know if you have any suggestions for leap year.
