Hosting Checker
Free hosting checker — resolve any domain's IP address in your browser and identify where it points, with guidance on tracing the hosting provider.
About the Hosting Checker
Knowing which company hosts a website is handy for competitor research, troubleshooting, and choosing a provider. This free hosting checker resolves a domain's DNS in your browser to reveal the IP addresses it points to — the first and most important step in tracing where a site is hosted.
It queries A records over Cloudflare's DNS-over-HTTPS resolver, so you instantly see the live IP addresses behind a domain. From there the tool explains how to identify the hosting provider or CDN from that IP, including the reputable IP-and-ASN lookup services that map an address to its owning network.
Many modern sites sit behind Cloudflare or another CDN, so the resolved IP may belong to the CDN rather than the origin host — the tool notes this so you interpret the result correctly. It is a fast, honest way to start any hosting investigation.
How to Use the Hosting Checker
- 1Enter the domain you want to investigate.
- 2Click Check hosting to resolve its live IP addresses.
- 3Read the A records showing where the domain points.
- 4Use a linked IP/ASN lookup to identify the hosting provider or CDN.
Frequently Asked Questions
How can I tell who hosts a website?
Start by resolving the domain's IP address, which this tool does instantly. Then look that IP up in an ASN/IP database (like the ones we link to) to find the network that owns it — often the hosting company or CDN. The combination of IP plus ASN owner reveals the host in most cases.
Why does the IP belong to Cloudflare or a CDN?
Many sites route traffic through a content delivery network like Cloudflare, Fastly or Akamai for speed and protection. When they do, DNS resolves to the CDN's IP rather than the real origin server, so the hosting company behind it is hidden. The tool notes when a CDN is likely in play.
What is an ASN?
An Autonomous System Number identifies a network operator — a hosting company, ISP or cloud provider — that controls a block of IP addresses. Looking up an IP's ASN tells you which organisation owns that address space, which is how hosting is usually identified.
Does this reveal the exact server?
It reveals the public IP a domain resolves to, which points to the hosting network or CDN edge, not necessarily the specific physical machine. For most research purposes the hosting provider or cloud region is what matters, and that is what the IP and ASN together reveal.
Why do some domains return multiple IPs?
Large sites often publish several A records so traffic is spread across multiple servers or data centres for redundancy and load balancing. Seeing several IPs is normal and usually indicates a CDN or a load-balanced hosting setup.
