Hosting Checker

Free, no signup. See which public network and edge platform a domain exposes — and the specific DNS or response-header evidence for it.

Built by Patrick Stox

Checks run from our server; we fetch the URL you enter and don't keep the results. This queries public DNS and makes one public web request. A CDN or reverse proxy can hide the origin provider; this tool never treats edge evidence as proof of the origin. Anonymous run-level outcome counters may be used for aggregate research; URLs, domains, IPs, and identifiers are never included, and no statistic is released below 100 runs.

Sample report
Illustrative example — fixed public signals, not a domain lookup
Cloudflare is proxying this site; the origin host is not visible from this public check.
  • Evidence: server: cloudflare and cf-ray were present.
  • IP & network: the displayed addresses belong to the public edge network.
  • DNS & mail: an MX answer is listed separately and is not called the web host.
  • Transfer: Content-Encoding: br means Brotli was observed on this response.
 
 
 
How to use it
  1. Enter a bare domain such as example.com.
  2. Choose Check hosting and read the delivery verdict with its evidence.
  3. Separate the observed IP network, CNAME, and response-header fingerprints from the mail-host MX records.
  4. If a proxy is detected, treat the origin as unknown unless you can verify it through your own account or configuration.

How to read the result
  • Delivery verdict summarizes the strongest supported edge or ASN evidence.
  • Origin not visible means a proxy or edge platform terminates the public request.
  • IP network is the ASN organization for the observed A/AAAA address, not necessarily the hosting brand.
  • CNAME and MX are raw public DNS answers; MX describes email.
 
Data sources & freshness
The endpoint performs bounded public A/AAAA, CNAME, and MX lookups and one web request. Team Cymru ASN DNS data enriches observed IPs with network organization, registry, and country. A deterministic fingerprint table checks selected headers and CNAMEs for supported edge platforms, while transfer inspection reports compression and only documented protocol hints.
 
Features
  • Public IP, ASN, CNAME, and MX evidence in one report.
  • Supported CDN and edge fingerprints from DNS and headers.
  • Compression and protocol-hint summary.
  • Explicit distinction between delivery network, origin host, and mail host.
 
Limitations
A Cloudflare, Fastly, or similar result describes the public edge and may conceal the origin. ASN country is not a physical server location. Private DNS, multi-CDN routing, geographic answers, reseller relationships, and infrastructure without a supported fingerprint can make the picture incomplete.
 
Frequently asked questions
Can a hosting checker identify the origin host behind Cloudflare?
Usually not. A reverse proxy publishes its own edge IPs and headers while deliberately hiding the origin. The checker reports Cloudflare as the delivery layer and leaves the origin unclaimed.
Is the reported country the server location?
No. Country and registry values come from public ASN data for the observed IP network. They are not proof of the physical datacenter, origin server, or where site data is stored.
Why does the tool show a CDN instead of my web host?
Public DNS and HTTP requests terminate at the CDN or edge proxy when one is configured. That is the infrastructure visible to visitors; the underlying host may not expose a public fingerprint.
Does the MX record show who hosts the website?
No. MX records describe mail delivery. The report lists them separately because email and web hosting are often provided by different companies.

Sobre a ferramenta
Encontrar o público rede, CDN, proxy, cabeçalhos, DNS registros, e mail host associated com um domain — com o evidência behind cada conclusion.
Como usar Enter um bare domain such como example.com . Escolha Verificação hosting e leitura o delivery verdict com seu evidência. Separate o observado IP rede, CNAME, e response-header fingerprints de o mail-host MX registros. If um proxy é detected, trate o origin como unknown unless você pode verifique isso por seu own account ou configuração.
Recursos

Limitações
