Answer 1

FINDSTR is the only native batch utility that has any support for regular expressions. But the support is very limited and non-standard. The only repeat expression supported is *. In addition, it is limited to a maximum of 15 character class terms (see What are the undocumented features and limitations of the Windows FINDSTR command?). So I don't think it is possible to develop a native batch regex that will precisely match an IP address.

You could stay within native windows utilities and use Power Shell, or you could use JScript or VBScript via the CSCRIPT command. All three have much better regex support.

Alternatively you could download any of a number of Windows ports of Unix utilities, many of them free. GnuWin32 is a good resource (includes grep): http://gnuwin32.sourceforge.net/
