Testing a valid IP address format is a little more involved. For example,
24.75.345.200 looks valid enough (the director to the movie "The NET"
thought so) but it isn't.

Here is code I would use in this case (watch for line wrap):-

Const csPatternIP =
"^(((\d{1,2})|(1\d{2})|(2[0-4]\d)|(25[0-5]))\.){3}((\d{1,2}) |(1\d{2})|(2[0-4
]\d)|(25[0-5]))$"

If (NewRexExp(csPatternIP).Test(sIP) Then
'IP seems good
Else
'IP is clearly invalid
End If

Function NewRegExp(rsPattern)

Set NewRegExp = new RegExp
NewRegExp.IgnoreCase = rbCaseInsensitive

End Function

It wouldn't have to check to see if it is an actual working IP, just check
to see if it meets the ip criteria, which should be 4 groups of numbers that
can be one digit to four digits per group.

You meant of course 3 digits per group. The RegEx pattern also tests that
the number in each group is between 0-255.
