FAQ

What does the hosting field mean?

We match the network's ASN and organisation against known cloud, CDN, hosting and ISP networks (AWS, Google Cloud, Cloudflare, Hetzner, OVH and many more) and say how confident the match is.

Do you show who owns an IP address?

We show the network owner from the regional registry (an organisation such as an ISP or cloud company). Individuals are never named.

Can I look up a domain instead of an IP?

Yes. Enter a domain and we resolve its IPv4 and IPv6 addresses and look up each one.
