What Is a Website Hosting Checker?
A website hosting checker is a free online utility that lets you instantly discover which hosting provider powers any website on the internet. Whether you are a web developer scouting competitors, a business owner researching potential hosting partners, or simply curious about the infrastructure behind your favorite sites, this tool gives you the answers in seconds.
Our hosting checker resolves the domain’s DNS records, identifies the IP address the site points to, queries global IP intelligence databases, and determines the Internet Service Provider, data center organization, geographic server location, autonomous system number, and active nameservers. All of this happens automatically — you just enter a domain and click one button.
The tool supports bare domain names like example.com, subdomains like blog.example.com, and even full URLs such as https://www.example.com/page. We parse the hostname for you, so there is no need to worry about formatting.

Within seconds you will see a detailed breakdown including the hosting provider name, IP address, server country and city, ASN, nameservers, and more.
Comprehensive Hosting Intelligence
Every lookup returns a rich set of data points that paint a full picture of the website’s hosting infrastructure.
Hosting Provider
Identify the company that hosts the website, whether it is Amazon AWS, Cloudflare, Google Cloud, DigitalOcean, or any other provider.
IP Address
See the public IPv4 address that the domain resolves to. Useful for network diagnostics, firewall rules, and technical troubleshooting.
Server Location
Find out in which country, region, and city the hosting server is physically located, along with the associated timezone.
ASN Details
View the Autonomous System Number and the organization that owns the IP block, giving deeper insight into the network infrastructure.
Nameservers
Discover the active nameservers for the domain. Nameservers often reveal whether the site uses Cloudflare, Route 53, or another DNS service.
ISP Information
Learn which Internet Service Provider manages the IP range, which is especially helpful for identifying shared hosting environments.

Frequently Asked Questions
Find answers to the most common questions about our website hosting checker tool below.
A website hosting checker is an online tool that identifies which company hosts a given website. It works by first resolving the domain’s DNS records to find the IP address, then querying IP intelligence databases to determine the organization, ISP, and data center behind that IP. Our tool also fetches the domain’s nameservers to provide additional context.
Yes, this tool is completely free with no sign-up required. You can perform unlimited lookups without creating an account or providing any personal information. There are no hidden fees or premium tiers.
You can check any publicly accessible domain. This includes standard websites, blogs, e-commerce stores, SaaS platforms, and more. The only requirement is that the domain has valid DNS records. Private or internal domains that do not resolve publicly cannot be checked.
Nameservers control where a domain’s DNS queries are handled. They often reveal the DNS or hosting provider. For example, nameservers like ns1.cloudflare.com indicate the site uses Cloudflare for DNS, while ns-xxx.awsdns-xx.com points to Amazon Route 53. However, the DNS provider and the hosting provider can sometimes be different companies.
Many websites use CDNs (Content Delivery Networks) like Cloudflare, Fastly, or AWS CloudFront in front of their origin server. In these cases, the IP address resolves to the CDN’s infrastructure rather than the actual hosting server behind it. The reported provider will be the CDN. This is normal and still provides useful insight into the site’s architecture.
Our tool uses Google’s public DNS API and reputable IP geolocation databases, so the results are highly accurate for IP resolution, ISP identification, and country-level location. City-level geolocation can occasionally be approximate, especially for cloud providers with distributed data centers.
