I'm having the same problem utilizing this method of checking ip addresses. For those of us (assuming most of us) that are doing stealth with multiple accounts, it doesn't really matter if the ip address is a duplicate of an address that was used before for that same account.
Example: column A is date logged in, and column B is ip address used. Both columns are under Stealth Account X. Using this method, red would flash for the entire column B if the ip address was used before in that column, and green would flash for the column if the ip address was not ever used before for this particular Account X. Even if it flashes red indicating a duplicate ip, it doesn't matter because that ip is linked already to the particular account anyways. We would be able to use it without fear of any linkage to begin with.
We are more interested in cross-referencing these ip addresses with OTHER stealth accounts, in order to make sure that a different ebay/paypal has never before used the ip address we want to use. So using the excel spreadsheet, if Stealth Account X has columns A (for date logged in) and B (for ip address used), then Stealth Account Y has columns C (for date logged in) and D (for ip address used), and Stealth Account Z has columns E and F. We want to check if the ip address we put into column B has been used in columns D and F for the other accounts.
Much more useful would be something that flashes in the other columns for ip address. I hope this makes sense!
I have my spreadsheet set up the same as MM78's. You can see the screenshot a couple posts above.
