Where is this site hosted?
Host, network and CDN.
Type any website. We look up its public DNS, the network that owns its IP address and the headers its server sends, and tell you who hosts it, what sits in front of it, and who handles its DNS and email.
Uses public DNS and one ordinary page request. IP ownership comes from Team Cymru’s public IP-to-network service.

Questions people ask
Why can’t you always name the host?
When a site sits behind a CDN such as Cloudflare, visitors only ever reach the CDN, so the real server’s address is hidden. We say so instead of naming the CDN as the host. Often the host still shows itself in a header, and then we name it.
Is the country where the server is?
It is where the network is registered, which is usually close but not always the same as the data centre. CDNs serve from many countries at once.
Why does hosting matter for my business?
Hosting decides how fast pages load for your visitors, how well the site survives a traffic spike or an attack, and who you call when it goes down. It is also where a lot of slow-site problems start.
