Answer 1

A simplistic regex string would be

(1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])\.(1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])\.(1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])\.(1?[0-9]?[0-9]|2[0-4][0-9])|25[0-5]

to match exactly the range of allowable IP addresses.

EDIT: Based on comments below and Regular expressions in findstr information, modify the above regex to [0-2][0-9][0-9]\.[0-2][0-9][0-9]\.[0-2][0-9][0-9]\.[0-2][0-9][0-9] to match IP addresses. Apparently FINDSTR really is that limited in regular expression interpretation.
