# Who Hosts This Website

Find who hosts a website: follow its CNAME chain to the A and AAAA addresses, then name the network that owns each address (ASN, organisation, country).

## Capabilities and processing

Enter a domain or one or more IP addresses. Our server follows the CNAME chain, reads the A and AAAA records, and looks up the network that announces each address: autonomous system, organisation, country and reverse DNS.

A bare domain is looked up together with its www name, because the two are often hosted differently. Private, loopback and other non-public addresses are named as such.

## Example workflow

On the sample domain, www resolves to a CDN network while the bare domain resolves to a cloud network. HTTP checks are needed to establish redirects or whether the same origin is exposed.

## Limits and interpretation

The announcing network may be a hosting provider, CDN or shared network; it does not prove who operates the website or identify a hidden origin. Country is network registration data, not server geolocation. Sample answers use documentation addresses. Nothing is stored.
