IP Address Lookup
Enter any IP address to see its approximate location, network and time zone.
This IP lookup tool takes any IPv4 or IPv6 address you type in and reports what public data knows about it: the approximate country, region and city, the internet provider or network that owns it, and the time zone that address maps to. It is useful for making sense of an address in a server log, an email header, a firewall block list or a suspicious sign-in alert.
The lookup queries a public IP geolocation service and shows what it returns. Be clear on what that means: geolocation is an estimate, not a home address. It works by mapping the address to the network that registered it, so the result points at the ISP or data centre, never at a named person.
Accuracy varies a lot. Country is usually right; city is often approximate and can be off by a long way for mobile connections, VPNs, corporate networks and cloud servers, where the registered location may be a national hub rather than the real user. Treat the city as a hint, not a fact.
How to look up an IP address
- Type or paste the IP address you want to check into the box.
- Press Look up.
- Read the results: country, region, city, ISP or network, and time zone.
- Compare it against what you expected, for example the region a sign-in should have come from.
- Clear the box and enter another address to check a different one.
What IP geolocation can and cannot tell you
Geolocation answers 'which network is this and roughly where is it registered', not 'who is this person and where do they live'. The data comes from regional internet registries and provider records, so it identifies the ISP or hosting company and their general service area.
Expect it to be least accurate for mobile data (the address may map to a carrier's central hub), VPNs and proxies (you see the exit server's location), business and university networks (registered to a head office), and cloud providers (the data centre region). If pinpoint accuracy mattered, this method would not provide it, and no public tool honestly can.
How the lookup works
When you enter an address and press Look up, the tool sends that address to a public geolocation API (such as ipwho.is) and displays the fields it returns. Those services build their data by combining the public registry records that say which organisation owns a block of addresses with additional signals about where that network is used. There is no secret database of individuals behind it; it is registry data plus estimation.
This is different from the file-based tools on the site, which never send anything anywhere. An IP lookup is inherently a network operation: the address has to be checked against a remote dataset, so the address you type does leave your device by design. That is the honest trade-off for getting location and network detail on any address, not just your own.
How to read the fields you get back
Country and continent are the most trustworthy lines and are usually correct. Region and city are best read as 'somewhere in this general area', because they reflect where the network is registered or concentrated rather than where a specific user sits. The ISP or organisation field is often the most useful of all, since it tells you whether an address belongs to a home broadband provider, a mobile carrier, a hosting company or a corporate network.
The time zone is derived from the estimated location, so it inherits the same uncertainty, but it is handy for judging whether a log entry lines up with a plausible working hour for that region. If the organisation field names a well-known cloud or VPN provider, treat the city as almost meaningless and focus on the fact that the traffic came from infrastructure rather than a residential line.
Everyday uses for an IP lookup
The common one is investigating a suspicious sign-in alert: you get an email saying your account was accessed from an unfamiliar address, and a quick lookup tells you the country and provider so you can judge whether it plausibly came from you, a VPN you use, or somewhere you have never been. It is also the standard way to make sense of the raw addresses in a web server access log or a firewall's blocked-connection list.
Developers and admins use it to sanity-check where a service is hosted, to confirm a VPN is exiting in the country they expect, or to decide whether an address in an email header matches the sender's claimed origin. In each case the goal is context and a plausibility check, not proof, which is exactly what registry-based geolocation is good for.
Privacy and how sensitive this data is
An IP address is personal-adjacent data: on its own it does not name anyone, but combined with the provider's own logs it can be tied to a customer, which is why only the ISP holds that link and only a lawful request can compel it. Looking up an address here reveals no more than its network and rough region, and this page does not save the addresses you enter.
Because the address you type is sent to a third-party geolocation service to produce the result, avoid using the tool for anything you are contractually or legally required to keep confidential. For ordinary troubleshooting and awareness it is perfectly appropriate, but treat it as you would any tool that queries an external API rather than assuming the input stays wholly private.
Limits and accuracy in practice
The single biggest limitation is that a lookup locates a network, not a device. Carrier-grade NAT means thousands of mobile users can share one visible address; a company can route an entire office through one gateway; a VPN deliberately masks the real origin. In all these cases the 'city' is at best where the exit point is registered, and it can be hundreds of kilometres from any actual user.
Coverage also differs by dataset and by address type. IPv6 geolocation is often thinner than IPv4, freshly reassigned blocks can carry stale location data for a while, and no free service publishes a guaranteed accuracy figure, so anyone quoting one should be treated with suspicion. Use the result as one signal among several, never as a definitive answer.
Related network tools
If you want to know your own public address before looking others up, the What Is My IP tool shows your IPv4 and IPv6 directly. It is the natural first step, since many people arrive here after spotting an unfamiliar address and wanting to compare it against their own.
For domain-level investigation, the DNS Lookup tool resolves a domain to its A, MX, NS and other records, which is often what you need when an address in a log traces back to a hostname you want to understand. The User Agent checker rounds out the set by showing what a browser reports about itself, useful when a security alert lists both an IP and a device string.
Frequently asked questions
Is this IP lookup free?
Yes, free with no sign-up. Look up as many addresses as you need using public geolocation data.
How accurate is the location?
Country is usually accurate. City is approximate and can be wrong, sometimes by hundreds of kilometres, especially for mobile, VPN, business and cloud IP addresses. Read it as a rough guide.
Can I find the exact person or address behind an IP?
No. IP geolocation locates the network and its provider, not an individual. Only the ISP holds the customer records, and only a lawful request can link an address to a person.
Why does the result show a city I have never been to?
Your provider may register a wide area under one location, or route you through a distant hub. VPNs show the server's location instead of yours. All of this is normal and expected.
Can I look up IPv6 addresses too?
Yes. Enter an IPv6 address the same way. Geolocation coverage for IPv6 can be thinner than IPv4, so some results may be less detailed.
Is my search stored?
The address you enter is sent to a public geolocation service to fetch the result and is not saved by this page. Avoid using it for anything you must keep confidential.
