IP address lookup
Enter any IP address to see where it is, whose network it belongs to, and whether it is a known proxy. All from our own live network data, no signup.
What an IP lookup tells you
An IP address is how one machine on the internet reaches another, and a surprising amount about it is public by necessity rather than by leak: the country and city it is registered to, the network operator that announces it, and whether it sits in a datacenter or on a home connection. This tool reads all of that from our own network data and shows it in one place, for any address you enter.
What makes this lookup different from the dozens of others is the last line of the answer. Because we run our own proxy checker around the clock, we can also tell you whether an address is, or ever was, an open proxy, which no general geolocation tool knows. If the address is in our database, the result links straight to its full record.
The single most consequential field is not the location, it is the ASN. Every public address belongs to an autonomous system, and which organisation owns it is a matter of public record, so a site can classify you as household or hosting in one cheap lookup before it examines anything about your request. That classification does more work than the city, the country or anything you do afterwards.
Which is also the honest caveat about the location. Country accuracy is generally good. City accuracy is frequently wrong by a wide margin, because geolocation is inference from registration records and routing behaviour rather than a measurement of where a device physically is. Treat the country as dependable and the city as a hint, and be suspicious of any tool presenting a street-level result as fact.
Two more things worth knowing before you read too much into a single result. An address rarely maps to one person: home routers put every device in a household behind one public address, and carrier-grade NAT puts many subscribers behind one on mobile networks, so a lookup describes a connection point rather than an individual. And ownership changes, since ranges are transferred and companies acquired, so a database can describe an address as it was rather than as it is.
The practical uses follow from all of that. Checking what a website sees when you connect through a proxy, so you can confirm the exit node and its country rather than assuming. Investigating an address that turned up in a server log. Or checking whether an address you have been given is really residential before you pay for it as such.
Where an address is
Country, region and city, with coordinates and timezone. Enough to know which market an IP sits in, without pretending to a precision geolocation cannot deliver.
Whose network it is on
The ASN and operator that announce the address, plus whether it is a datacenter or a residential connection, which is the single fact most sites weigh when they judge traffic.
Whether it is a proxy
A check against our permanent proxy database: live now, seen before, or never recorded. The one thing a plain geolocation lookup cannot answer, from the network that measures it.
Questions about IP lookups
What is an IP lookup?
An IP lookup takes an IP address and returns what is publicly known about it: the country, region and city it is registered to, the network operator that announces it, and whether it belongs to a datacenter or a consumer connection. It does not reveal a person; an IP identifies a network endpoint, not an individual.
How accurate is IP geolocation?
Country is almost always right. City and region are estimates: they come from the network's registration and routing, not a GPS fix, so they place you in the right area rather than at an address. A datacenter or proxy IP will show the location of the server, which is exactly why they are used to appear somewhere else.
What is an ASN, and why does the lookup show one?
An ASN, or Autonomous System Number, identifies the network that announces an address to the rest of the internet, usually one company. It is often the most telling fact about an IP: it tells you whether an address belongs to a hosting company, a cloud platform or a home ISP, which is what most sites actually react to when they decide whether traffic looks ordinary or automated.
Can this tell me if an IP is a proxy?
Yes, to the extent that we have ever seen it. Alongside the location and network, the lookup checks the address against HProxy's public proxy database, which tracks every open proxy we have ever recorded. If the address is a live or previously-seen proxy, the result links to its full record with the dates and check history.
Is my own IP address private?
Your IP is visible to every site you connect to, by design: it is the return address your traffic needs. What a lookup adds is only what is already public about the network behind it. If you want sites to see a different address, that is what a proxy or VPN changes, and it is what our per-IP pages measure.
Is this IP lookup free?
Yes, with no signup and no key. The same data is available through our public API for anyone building a tool of their own. It is rate-limited to keep it fair, not to gate it.
