How it works

We resolve the domain's A and AAAA records and, for each IP, query the regional Internet registry (ARIN, LACNIC, RIPE…) over RDAP to find which organization and network it belongs to. If the site uses a CDN such as Cloudflare, you'll see the CDN's IP rather than the origin server's, which stays hidden.

How to use it, step by step

  1. Enter a domain or an IP address.
  2. We resolve its addresses and look up the network and country they belong to.
  3. You'll see the provider, country, network block and whether it sits behind a service like Cloudflare.
  4. Use it to find out where a site is hosted.

What it's useful for

  • Find out which provider hosts a website.
  • Check whether your domain already points to your new server.
  • Identify where a suspicious IP in your logs comes from.

FAQ

Can I tell where a site is hosted from its IP?

Usually, yes: the network and autonomous system (ASN) point to the hosting provider. If it's behind a CDN, you'll only see the CDN.

Why does a domain have several IPs?

For load balancing and redundancy. CDNs and large services return several IPs and may change them depending on where the request comes from.

Is IP location exact?

It reflects the network registration, usually country and provider. It doesn't identify a person or a street address.

Why do several domains share an IP?

They share a server (shared hosting) or sit behind a content delivery network like Cloudflare.

What is IPv6?

The newer IP address format with vastly more combinations. You'll see long strings with colons.

What does being behind a CDN mean?

The IP belongs to an intermediary that protects and speeds up the site; the real server stays hidden.

Can I find out who owns an IP?

You'll see the organization that manages it (the provider), not the specific customer using it.
