How these tools are built

Every lookup runs on our own servers against free, regularly refreshed datasets (DB-IP Lite for geolocation, iptoasn for networks, the Tor exit list, Spamhaus DROP, the IEEE OUI registry) and live protocols (DNS, DNS-over-HTTPS, RDAP). We show the data source on each page and never hide a result behind a sign-up.
