([0-9]{3,}\.){3,3}[0-9]{3,}
By putting in this regex expression it will look for a parameter in the format xxx.xxx.xxx.xxx (but not xx.xx.xx.xx or similar) Is that what you're after?
Also, F5 has a neat regex validator tool (App Security, Options, Tools, RegExp Validator) where you can pop this string in and enter a test string e.g. 111.111.111.111 as an example, and it will tell you whether there's a match or not.
Hope this helps,
