Domain Hosting Checker
Last updated:
Find out where any domain is hosted. We resolve the IP, read the reverse DNS and ASN, and identify the hosting provider, DNS provider, and mail provider in one clean report.
Enter a domain to check hosting:
How the Checker Works
- Resolve the domain, A and AAAA records reveal the server IP.
- Look up the network, ASN and organisation identify the host.
- Read DNS and mail, nameservers and MX records are parsed.
- Summarise, you get host, DNS, and mail providers at a glance.
Why It Matters
- Migration planning, know the current setup before you move.
- Competitor research, see what infrastructure others use.
- Troubleshooting, confirm where requests actually land.
- Verification, check that a move or DNS change took effect.

Domain Hosting Checker: FAQ
What does the domain hosting checker do?
It resolves a domain to its IP addresses, performs a reverse DNS lookup, identifies the hosting provider and network through ASN data, and lists the nameservers, DNS provider, mail records, and likely mail provider.
How does it identify the hosting provider?
It resolves the A and AAAA records to find the server IP, then queries IP intelligence data for the organisation and autonomous system number that owns that address, which maps to the hosting company or network.
What is the difference between hosting and DNS provider?
Your hosting provider runs the server that serves your website, while your DNS provider answers the queries that tell browsers where that server is. They are often different companies, for example a site hosted on one platform with DNS managed by another.
Why would I check where a domain is hosted?
It is useful for competitor research, migration planning, troubleshooting performance, verifying that a site moved correctly, checking whether a domain shares infrastructure, and confirming your own DNS and mail setup.
What does the mail provider field tell me?
The tool reads the MX records and infers the email provider behind them, for example a major email platform or a self-hosted mail server. This helps you understand who handles a domain email without guessing.
Is reverse DNS always available?
No. Reverse DNS depends on the network operator publishing a PTR record for the IP. Many hosts set one, but some leave it blank, in which case the tool shows the lookup as unavailable.
Is the lookup safe and private?
Yes. It uses public DNS and IP data, blocks private addresses, and stores nothing about your lookup.
Is this domain hosting checker free?
Yes. It is free, requires no signup, and works on any public domain.
