Umm, not quite. <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" />

If you enter 123.45.67 then the IP address MUST start with 123.45.67

So 123.45.678.9 would match (assuming it was valid - it ain't and I'm lazy <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" /> )

123.45.6 will:
NOT match 78.123.45.6
but WILL match 123.45.65.43

Edit: I guess I should point out - the reason that IP address up there ain't valid is because each node in an IP address must fall between 0 and 255 (and I'm not quite sure when those end points are allowed either).
