How to find out what host a website is using
Every website lives on a server owned by a hosting company — but most sites never say which one. The host matters when you are comparing providers, shopping for a competitor's setup, or troubleshooting a slow site, yet tracking it down usually means digging through DNS records by hand. This tool does that digging for you in seconds.
How to use it (3 steps)
- Type the domain. Enter any website address — example.com, google.com, or your own site. Web addresses with https:// or www. both work; the tool strips them.
- Click “Find the Host”. The tool queries public DNS records for that domain over the secure dns.google service.
- Read the result. If the nameservers or CNAME records match a known host, we tell you the company — for example, Hostinger for reviewkarts.com — and show the IP address, nameservers and CNAME records we found, so you can check the evidence yourself.
Worked example: reviewkarts.com
Take this very site as an example: typing reviewkarts.com gives Hostinger. Its two nameservers are artemis.dns-parking.com and hermes.dns-parking.com — and dns-parking.com is Hostinger's nameserver domain, so the match is direct. The tool also shows the site's IP addresses, so you can see the records behind the answer instead of taking our word for it.
How it works
When you type a domain into a browser, your computer asks the site's nameservers where to find it. Those nameservers have a name of their own, and most hosting companies use their own nameserver domains — which is why the nameserver name is often the clearest clue to the host. Cloudflare, for example, parks its customers on nameservers ending in ns.cloudflare.com; Google uses ns1.google.com through ns4.google.com.
The tool fetches three kinds of DNS record at once: the A record, which lists the site's IP addresses; the CNAME record, which points a hostname at another name; and the NS records, which name the site's nameservers. It then checks those values against a table of well-known hosting companies — Hostinger, Bluehost, SiteGround, GoDaddy, Namecheap, WP Engine, Kinsta, WPX, Amazon Web Services and Google — first looking at the nameservers, then at the CNAME records.
Cloudflare gets its own check: if the nameserver ends in cloudflare.com, or the site's IP addresses fall inside Cloudflare's published IP ranges, we flag the site as behind Cloudflare rather than naming a host that might be wrong.
Why some hosts can't be identified
Not every site leaves a fingerprint. Some hosts use generic nameservers that give nothing away, and a site parked on a server owned by a reseller or a private cloud account may show a server company's nameservers rather than the brand you paid. When that happens, the tool is honest: it says it couldn't identify the host and prints the IP address and the nameservers it found, so you can search those values yourself.
Cloudflare masks the host too, because it sits in front of the real server as a proxy: the IP address you see belongs to Cloudflare, not to the hosting company. DNS-over-HTTPS is the method behind all of this — the records we fetch are the same public records any DNS resolver would return, and they never include anything private about a site's owner, traffic or account.
Everything runs in your browser: the lookup goes straight from your device to dns.google, and nothing you type is stored or sent to ReviewKarts. The same public records are also what our WHOIS lookup tool checks when you want more detail about a domain's registration.
Frequently asked questions
How does it find the host?
It fetches the domain's public DNS records — the A, CNAME and NS records — and matches the nameserver and CNAME values against a table of known hosting companies. When a match is found, it reports that company and shows the record it matched.
What is DNS?
DNS, the Domain Name System, is the internet's phone book: it translates a human-readable name such as reviewkarts.com into an IP address and a set of records that say where the site, its email and its name servers live.
Why does it sometimes say Cloudflare?
Many sites sit behind Cloudflare, a proxy that protects them and speeds them up. The site's public IP address then belongs to Cloudflare, so the real host is hidden behind Cloudflare — the tool says so instead of guessing.
Is the result always exact?
No. This tool works from public records, and those only show the front door. A proxy or shared hosting platform may only show the proxy or platform, not the company behind it — so treat the result as strong evidence, not a guarantee.
Is it free, and does it store the domain I type?
Yes, it is free, and no — everything runs in your browser, and nothing you type is stored or sent to ReviewKarts. Only public DNS records are read.
