  • Wrong location for your IP? We do not control geolocation data. Location comes from the IP geolocation provider, which in turn relies on registry and ISP data. Read how to correct your IP location.
  • Want to know who owns a domain or IP? Use the WHOIS lookup and contact the abuse address it shows. We cannot identify the people behind IP addresses.
  • Reporting abuse from an IP address? Contact the network's abuse team shown in WHOIS. We are not the owner of the addresses displayed on this site.

We welcome

  • Bug reports and tool suggestions.
  • Corrections to our guides.
  • Partnership, advertising and API usage enquiries.
  • Privacy requests about your personal data (see our privacy policy).
