Domain Hosting Checker

Find hosting, IP, nameserver, CDN, and server signals for a domain.

Lookup settings

Keep public checks focused and lightweight. Advanced dashboard checks can include saved history and monitoring.

Show approximate server location
Uses IP geolocation and may show CDN or proxy location instead of the origin server.
Detect CDN providers
Checks CNAME, nameserver, ASN, and HTTP header patterns.
Include server technology hints
Uses visible HTTP headers only. Results may be limited or hidden by proxies.
Follow redirects
Follows standard HTTP redirects to inspect the final response headers.

Uses DNS, ASN, reverse DNS, HTTP header, and CDN pattern checks. Results may vary by resolver and cache.

Free public checks are limited to 3 uses/day. CAPTCHA may appear for protection.

What Wranker checks

Public hosting signals, organised for technical SEO.

A hosting checker is most useful when it separates DNS, network ownership, CDN evidence and visible HTTP hints without claiming private origin data it cannot confirm.

Use it during internal linking audits, content optimisation, technical SEO reviews, website migrations and content hub planning.

Hosting visibility

Identify provider and server signals

Review detected hosting, network owner, primary public IP and visible server hints from public lookups.

DNS clarity

Inspect nameserver and DNS context

Check active nameservers, DNS provider hints, CNAME clues and hostname normalisation before deeper audits.

Proxy awareness

Detect CDN or edge masking

Use CNAME, nameserver, ASN and HTTP header evidence to understand when a CDN may be hiding the origin server.

Network review

Estimate location and ownership

See approximate IP-based city or country, ASN or ISP ownership and reverse DNS availability where public data allows.

Why it matters

Hosting visibility helps teams audit before they guess.

Knowing where a site appears to be served from supports migrations, CDN reviews, client onboarding, redirect troubleshooting and competitor discovery. Wranker keeps the output practical by labelling public signals as evidence rather than absolute proof.

Migration checks stay clearer

Validate whether IP, nameserver or CDN signals changed during a website migration or DNS update.

CDN findings are treated carefully

Wranker frames CDN and proxy evidence as directional, so teams avoid mistaking an edge IP for confirmed origin hosting.

Agency reviews move faster

Collect hosting, DNS, ASN and header hints in one place before onboarding, troubleshooting or competitor research.

How it works

From hostname to hosting context in four focused steps.

The landing page captures the input and scope. The structured result opens after submission inside the checker output experience.

01

Enter a domain

Add a root domain, www hostname, subdomain or full URL. Email addresses, localhost, raw IPs and custom ports are not accepted.

02

Configure the signal scope

Choose whether to focus on the entered host, root and www context, or CDN-aware checks before running the lookup.

03

Run public checks

Wranker normalises the hostname and checks DNS, network, reverse DNS, CDN and HTTP header signals where available.

04

Review in the output dashboard

Open a structured result with overview, network details, nameservers, server hints, recommendations and raw public data.

When to use it

Useful when hosting details affect SEO decisions.

Use hosting checks as part of audit discovery, migration QA, CDN reviews and monitoring setup before deeper technical validation.

SEO audits

Answer where a client site appears to be hosted and capture hosting-related context for technical SEO reviews.

Website migrations

Check whether IP, nameserver, redirect or CDN signals changed after launch, DNS updates or platform moves.

DNS troubleshooting

Review nameserver visibility, CNAME clues, public IPs and partial lookup notes when infrastructure signals look inconsistent.

Competitor research

Understand which public network, CDN or DNS patterns competitors appear to use without exposing private backend data.

FAQ

Domain hosting checker questions,. answered

Practical answers about hosting signals, CDN masking, nameservers, ASN data and report availability.

A Domain Hosting Checker is a tool that helps identify hosting-related signals for a domain, including IP address, hosting provider, ASN, nameservers, CDN status, approximate location and visible HTTP header hints.

Enter a domain such as example.com and click Check Hosting. Wranker checks public DNS, network and HTTP header signals to show where the website appears to be hosted.

Yes. A CDN, reverse proxy or security layer can hide the true origin server. In that case, the visible IP and location may belong to the CDN provider instead of the hosting provider.

No. Server location is approximate and based on public IP geolocation. If the website uses a CDN or proxy, the location may reflect an edge server rather than the origin server.

Nameservers are authoritative DNS servers that tell the internet where to find DNS records for a domain. The nameserver provider may be different from the hosting provider.

ASN stands for Autonomous System Number. It identifies the network that owns or announces the IP address. The ISP or network owner can help identify the hosting or CDN network.

No. The public Domain Hosting Checker shows current hosting signals only. Hosting history and change monitoring can be handled inside the Wranker dashboard.

The public version is designed for domain checks. Raw IP lookup should be handled as a separate mode or separate tool if supported later.

Yes. Where export is available, you can download the public hosting result as CSV or PDF.

Some websites block automated requests, require specific protocols, sit behind security layers or hide headers through proxies. In that case, Wranker may still show available DNS and network data.
