How do I find out who hosts a website?

Enter the website's domain name or URL into our hosting checker tool. We instantly resolve the domain's DNS records, identify the IP address, and match it against our database of hundreds of known hosting providers.

What is a hosting checker?

A hosting checker is a free online tool that identifies the web hosting provider behind any website by performing DNS lookups, analyzing nameservers, and cross-referencing IP address ranges with known hosting companies.

How to find the hosting provider of a website?

Use our free hosting checker tool. Paste the website URL or domain name, click Find Host, and we'll show you the hosting provider, IP address, server location, and DNS records in seconds.

Is this hosting checker tool free to use?

Yes, our hosting checker is 100% free with no signup required. You can check unlimited domains and get instant results.

What information does the hosting checker show?

Our tool shows the hosting provider name, server IP address, physical server location, nameservers, and key DNS records including A, AAAA, MX, NS, TXT, and CNAME records.

Can I check who hosts a competitor's website?

Absolutely. Our hosting checker works with any publicly accessible domain, commonly used by web developers, SEO professionals, and business owners to research competitor hosting setups.

How accurate is the hosting checker?

Our hosting checker uses real-time DNS resolution and IP geolocation data, cross-referenced against an extensive database of hosting providers. Results are highly accurate.

What is the difference between a hosting provider and a domain registrar?

A domain registrar is where you purchase and manage your domain name. A hosting provider stores your website files on a server and makes them accessible online. They can be the same company or different ones.

Why does my website show Cloudflare as the host?

If your website uses Cloudflare's CDN, DNS queries resolve to Cloudflare's servers rather than your origin hosting server. Your actual hosting provider is behind Cloudflare's network.

Where is this site hosted? How do I check?

Use our free web host checker — enter any domain to find out where a website is hosted, who the hosting provider is, and where the server is located. Works for any domain worldwide.

How do I find the IP address of a website?

Use our hosting checker — enter the domain and we display the IPv4 (A record) and IPv6 (AAAA record) addresses along with geolocation and hosting provider identification.

What are nameservers and why do they matter?

Nameservers are specialized DNS servers that store DNS records for a domain. They control how traffic reaches your site — incorrect nameserver settings can take your website offline.

How do I check if a website uses Cloudflare?

Enter the domain into our hosting checker. If the site uses Cloudflare, the nameservers will typically end in .ns.cloudflare.com and the IP address will belong to Cloudflare's network range.

What is WHOIS and how does the WHOIS lookup work?

WHOIS is a public database of domain registration records maintained by ICANN. Our WHOIS lookup queries this database to show domain registration date, registrar name, expiry date, and domain age.

IP Checker — What's My IP & IP Host Lookup

Our free IP checker shows your public IPv4 address instantly, plus lets you look up any IP's hosting provider, ASN, and geographic location. Useful for VPN verification, firewall whitelists, network troubleshooting, and answering 'what is my IP' or 'ip host checker' queries.

What is an IP checker?

An IP checker displays your public IP address — what websites and servers see — and lets you inspect any IPv4 or IPv6 address to reveal its owning organisation, hosting company, country, and city.

Public vs private IP

Your private IP (192.168.x.x or 10.x.x.x) is only visible inside your local network. Your public IP is what every website sees — assigned by your ISP, and what we display at the top of this page.

IP host checker for domains

Enter a domain instead of an IP and the same engine resolves it to a server IP, then identifies the hosting company. The same lookup powers our main host checker on the home page.

Common IP-checker use cases
Use case	Why your IP matters
Firewall whitelisting	Allow your office IP into a private system
VPN verification	Confirm your VPN exit node is masking your real IP
Remote access setup	Share your home IP for SSH or RDP
Geo-region checks	See what country a service thinks you are in
IP reputation	Spot if your IP is on a spam blocklist

Frequently Asked Questions

What is my IP address?

Your public IPv4 appears on this page automatically. It's what websites and servers see when you connect to them.

How does an IP host checker work?

It queries regional registry databases (ARIN, RIPE, APNIC, LACNIC, AFRINIC) to find the owning organisation of an IP, then matches that against known hosting providers.

Is the IP check tool free?

Yes — free with unlimited queries, no signup required.

Can I find the IP host of any website?

Yes — enter the domain or IP and the tool returns the hosting provider, city, country, and ASN.

Why does my IP change?

Most home ISPs assign dynamic IPs that rotate when your router restarts. Business connections usually get static IPs.
