Free IP / Domain Location lookup — find where a website is hosted
The IP / Domain Location tool is a fast, free IP address lookup that shows you where a website is hosted and which network runs its servers. Enter a domain or an IP and the tool resolves the domain to IP address, performs a reverse DNS lookup, and returns the approximate IP geolocation — country, region, city, ZIP, timezone and coordinates — plus the ISP, organisation and AS number behind it. It is the quickest way to find a server location, answer “what is my server IP?”, run an ISP lookup, or simply confirm a site’s hosting location.
How the IP / Domain Location tool works
Every lookup follows three transparent steps, and each value is observed directly — nothing is guessed:
- Resolve the domain to an IP. The tool performs a DNS lookup and returns the IPv4 address (or addresses) the domain currently points to.
- Reverse DNS lookup. It then runs a reverse-DNS (PTR) query on that IP to reveal the hostname the network operator has assigned to it — often a clue to the hosting provider or data centre.
- Approximate geolocation from a named source. Finally, it fetches the IP’s registered location and network details from ip-api.com, a free public geolocation service, and clearly attributes the data to that source.
What the results mean
The report combines DNS facts with third-party geolocation. Here is what each field tells you:
IP address
An IP address is the numeric identifier a domain resolves to on the internet — for example
93.184.216.34. It is the address other computers use to reach the server that hosts the site. A
domain can point to more than one IP (for load balancing or a CDN), so this domain to IP check
may list several addresses.
Reverse DNS (PTR)
Reverse DNS maps an IP address back to a hostname, the opposite of a normal lookup. A PTR record
such as server42.examplehost.net frequently reveals the hosting company or data centre that operates
the address, which is useful for identifying infrastructure and diagnosing mail deliverability.
ISP and organisation
The ISP (internet service provider) and organisation fields name the company that owns or leases the IP — typically a hosting provider, cloud platform or network operator. An ISP lookup quickly tells you whether a site sits on shared hosting, a major cloud, or a dedicated network.
AS number
The AS number (Autonomous System Number, e.g. AS15169) identifies the larger
network that routes traffic for the IP. Two different IPs sharing an AS number usually belong to the same
provider, which helps you map how a site’s infrastructure is grouped.
How IP geolocation works — and why it is approximate
IP geolocation works by looking up an IP address in databases that record where each block of addresses is registered and, where possible, where it is actually used. Providers build these databases from regional internet registry allocations, network routing data, and other signals. Because the mapping is based on registration and network data rather than GPS, the result is an approximation: it reflects the IP’s registered location — very often the hosting provider or data centre — not a precise physical address, and never the individual person using the connection.
Accuracy varies widely. Many IPs resolve reliably to the correct country and often the right city, but cloud platforms, CDNs, VPNs and proxies routinely report the location of a distant data centre or exit node instead of where the content or user really sits. That is why our tool labels the geolocation as approximate and attributes it to its source: it is a strong indicator of the hosting region and network, not a definitive location.
Common uses for an IP / domain location lookup
- Check hosting location. Confirm which country and provider a website is hosted with before buying, migrating, or auditing a site.
- Detect a CDN. If the geolocation and reverse DNS point to a well-known content-delivery network, you know the site sits behind edge caching rather than a single origin server.
- Server location for SEO and latency. Hosting close to your main audience can reduce latency and improve real-world load times; this lookup helps you verify where the origin actually lives.
- Diagnostics and troubleshooting. Resolve a domain to its current IP, check reverse DNS, and identify the ISP when debugging DNS changes, mail issues, or connectivity problems.
- Answer “what is my server IP?” Enter your own domain to see the exact IP it resolves to and the network details registered to it.
Accuracy and privacy notes
Please read the geolocation as a guide, not a guarantee. The city, region and coordinates describe where the IP is registered, which is commonly the hosting location or data centre — the physical premises of a site’s visitors are not shown, because an IP does not identify a person. Never use IP geolocation to try to locate or identify an individual; it is neither designed nor reliable for that purpose. The IP and reverse-DNS values are drawn from live public DNS, and the location and network fields are provided by the named third-party service and can lag behind real-world changes.
Best-practice checklist
- Treat every geolocation result as approximate — verify against the provider’s own documentation when precision matters.
- Use the reverse DNS hostname and AS number together to confirm the true hosting provider, not just the city.
- Expect CDN and cloud IPs to report an edge or data-centre location rather than your origin server.
- Cross-check a domain’s IP address after DNS changes to make sure it points where you expect.
- Never rely on IP geolocation to identify a person, and respect privacy at all times.

Frequently asked questions
What is an IP / domain location lookup?
An IP / domain location lookup is a free tool that resolves a domain name to its IP address, runs a reverse-DNS lookup on that IP, and then fetches the approximate geographic location registered to it — country, region, city, ZIP, timezone and coordinates — along with the ISP, organisation and AS number. It shows you where a website is hosted and which network operates the server, all from public DNS and IP data.
How accurate is IP geolocation?
IP geolocation is approximate, not exact. It reflects the location registered to the IP address — usually the hosting provider or data centre that owns the server — rather than a precise street address. City-level accuracy is common for many IPs but can be off by a wide margin, especially for cloud, CDN and VPN addresses. Treat the result as a strong hint about the network and region, not a pinpoint on a map.
Can this tool find a person’s physical address?
No. An IP address identifies a network endpoint, not an individual. Our lookup returns the location registered to the IP — typically a hosting company, ISP or data centre — not the home or office of any person using it. IP geolocation cannot and should not be used to identify or physically locate a specific user.
Where does the geolocation data come from?
The approximate geolocation is fetched from ip-api.com, a free public IP geolocation service, and is clearly attributed to that source in the results. The IP addresses themselves come directly from live DNS resolution of the domain you enter, and the reverse-DNS hostname comes from a PTR lookup on the IP.
Is the IP / domain location tool free?
Yes, it is completely free with no signup. Enter any domain or IP address and get an instant report of the resolved IP, reverse DNS, and approximate geolocation. Every value is observed from DNS or the named geolocation source — nothing is invented or estimated.
