Look up the domain's DNS records and IP address, then identify the network/provider associated with that address.
Step by Step
- Find the domain's A/AAAA records.
- Note the returned IP address.
- Look up the IP network/provider information.
- Compare it with the domain's nameservers and known CDN/proxy services.
- Treat the result as infrastructure evidence rather than guaranteed proof of the origin host.
If That Doesn't Work
- Cloudflare and other reverse proxies can hide the origin server.
- A domain registrar, DNS provider, CDN, and web host can all be different companies.
