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.

حول الأداة
العثور ال عام شبكة, CDN, وكيل, رؤوس, DNS سجلات, و mail مضيف associated مع واحد نطاق — مع ال دليل خلف كل خلاصة.
مجاني, من دون تسجيل. انظر أي عام شبكة و حافة منصة واحد نطاق يكشف — و ال محدد DNS أو response-header دليل من أجل إنه.
الميزات
  • عام IP, ASN, CNAME, و MX دليل في واحد تقرير.
  • مدعوم CDN و حافة fingerprints من DNS و رؤوس.
  • Compression و protocol-hint ملخص.
  • صريح distinction بين تسليم شبكة, الأصل مضيف, و mail مضيف.
كيفية العمل
ال نقطة نهاية performs محدود عام واحد/AAAA, CNAME, و MX lookups و واحد ويب طلب. فريق Cymru ASN DNS بيانات enriches مرصود IPs مع شبكة مؤسسة, سجل, و country. واحد حتمي بصمة جدول تحقّقات مختار رؤوس و CNAMEs من أجل مدعوم حافة منصات, بينما transfer فحص يبلّغ compression و فقط موثق بروتوكول تلميحات.
القيود
  • واحد Cloudflare, Fastly, أو مشابه نتيجة يصف ال عام حافة و قد conceal ال الأصل. ASN country هو ليس واحد physical خادم موضع. خاص DNS, multi-CDN routing, geographic إجابات, reseller علاقات, و infrastructure من دون واحد مدعوم بصمة يمكن ينشئ ال picture غير مكتمل.
الأسئلة الشائعة
يمكن واحد استضافة فاحص حدّد ال الأصل مضيف خلف Cloudflare?
عادةً ليس. واحد عكسي وكيل ينشر الخاص به الخاص حافة IPs و رؤوس بينما عمدًا hiding ال الأصل. ال فاحص يبلّغ Cloudflare باعتباره ال تسليم طبقة و يترك ال الأصل unclaimed.
هو ال مُبلّغ عنه country ال خادم موضع?
لا. Country و سجل قيم يأتي من عام ASN بيانات من أجل ال مرصود IP شبكة. هم هي ليس دليل من ال physical datacenter, الأصل خادم, أو حيث موقع بيانات هو مخزّن.
لماذا يفعل ال الأداة اعرض واحد CDN بدلًا من my ويب مضيف?
عام DNS و HTTP طلبات terminate في ال CDN أو حافة وكيل عندما واحد هو مهيّأ. ذلك هو ال infrastructure مرئي إلى visitors; ال أساسي مضيف قد ليس يكشف واحد عام بصمة.
يفعل ال MX سجل اعرض من مضيفون ال موقع ويب?
لا. MX سجلات يصف mail تسليم. ال تقرير قوائم هم بشكل منفصل لأن بريد إلكتروني و ويب استضافة هي غالبًا موفّر بواسطة مختلف companies.
