I am not sure if this is possible or not. I have an excel workbook with 33 worksheets (or tabs). Each worksheet contains a list of network IP addresses (x.x.x.x - x.x.x.x). I would like to have an additional worksheet (using vlookup or something) where I can enter in a new IP address range. The formula would search to see if it could find that range in one of the 33 worksheets. If found, I would like the formula to return the worksheet name & specific cell reference.
