Hello, Let me guess: you want to make demographics of different ISPs' users for web advertising purposes and that is why you need to know which IP belongs to which ISP. RIPE database licence says you can't use their data for that purpose and I would be surprised if ARIN (or any of the others) allowed it. (Just as a reminder.) -- Aleksi Suhonen
