Your lookups

To show you your IP and answer your lookups (DNS, WHOIS, geolocation) we use your connection's IP and what you type into each tool. We do not store it, link it to you or send it to any third-party service: geolocation is computed on our own server. Your IP is only used for one minute to limit the number of lookups per person and prevent abuse.

How to change your choice

You can give or withdraw your consent at any time with the button below or the “Cookie settings” link in the footer. You can also delete cookies in your browser settings.
