Where the address is registered
Country, region and city come from a geolocation database that maps address ranges to the places their networks serve.

IP Address Lookup
Look up any IPv4 or IPv6 address, or a hostname, to see its country, region, city, network (ASN) and the organization that operates it.
The lookup runs on our own server against a local copy of the DB-IP Lite database, so the address you enter is not sent to a third-party service. We do not store your queries.
Look up an addressReady
What an IP lookup tells you
Which network it belongs to
The ASN and organization show the operator of the address range: a home broadband provider, a mobile carrier, a hosting company or a business network.
What a hostname points to
Enter a domain such as example.com and the tool resolves it first, then looks up the address it points to.
Whether a proxy exits where you expect
Look up the exit IP of a proxy to confirm its country and city before you point a scraper, a browser profile or an ad check at it.
Accuracy
How accurate is IP location?
- Country is reliable.
Address ranges are registered and routed per country, so the country is right for nearly every public IP.
- City is approximate.
It often shows where the network operator connects its customers, which can be a nearby larger city rather than the exact town.
- Coordinates are a center point.
They mark the city or region, never a street address. An IP address alone cannot reveal where a person lives.
- The data is refreshed monthly.
Addresses move between networks, so a result can lag a recent change by a few weeks.
What each field of the lookup means
Every field comes from one database lookup of the address. Nothing is measured live, so the result says where an address is registered and who operates it, not where a device is right now.
| Field | What it shows |
|---|---|
| IP address | The address that was looked up, IPv4 or IPv6. For a hostname, the first IPv4 address it resolves to, or its IPv6 address if it has no IPv4. |
| Country | The country the address range is registered and routed in. Right for nearly every public IP. |
| Region and city | The area the network serves. Often the nearest larger city or the place where the operator connects its customers. |
| ASN | The autonomous system number of the network that announces the address on the internet. |
| Organization | The operator of that network: a broadband provider, a mobile carrier, a hosting company or a business. |
| Approximate coordinates | The center of the city or region. Never a street address. |
Why two lookup sites can disagree. Each geolocation service builds its own database and updates it on its own schedule. When an address range moves to another network or another city, some databases follow within days and others within weeks. Country rarely differs between them; city often does. This tool uses DB-IP Lite and refreshes it every month.
What the network tells you about an IP
The organization behind an address says more about it than the city does. Websites use the same kind of data to decide how much to trust a visitor, so it helps to know which type of network an IP belongs to:
- Home broadband
- Organization is a cable, fiber or DSL provider. Addresses like these are what residential proxies use, and sites treat them as ordinary visitors.
- Mobile carrier
- Organization is a mobile network. Many phones share one address through carrier NAT, so the city is often far from the phone.
- Hosting or cloud
- Organization is a data center or cloud company. Servers, VPNs and datacenter proxies live here, and some sites limit or challenge traffic from these networks.
- Business or university
- Organization is a company, school or public body with its own network. Traffic from it usually leaves through a few shared gateways.
Checking a proxy. Find the exit IP of the proxy first: the Proxy Tester shows it, or open My IP in a browser that uses the proxy. Then look that address up here and compare the country, city and network with what you ordered. The proxy’s own host address is only the entry point and usually sits somewhere else.
Checking a server. Enter the domain name of a site to see which network hosts it and in which country. A site behind a CDN shows the CDN’s network and a location near the CDN’s edge, not the origin server.

Frequently Asked Questions
About IP lookups, accuracy and the data behind them.
All questions and answersCan an IP lookup find someone's home address?
No. The database maps address ranges to a country, region and city, often the place where the network operator connects its customers. It never contains street addresses or names.
Why does the city differ from where the person or server really is?
City data is approximate. Mobile carriers and many broadband providers route a whole region through a few points, so the city shown is often the nearest larger city. Country is reliable.
What is an ASN?
An autonomous system number identifies a network on the internet, such as a broadband provider, a mobile carrier or a hosting company. The organization next to it is the operator of that network.
Can I look up a domain name?
Yes. Enter a hostname such as example.com and the tool resolves it to its first IPv4 address (or IPv6 if it has none) and looks that up.
Where does the data come from?
From the DB-IP Lite city and ASN databases, which we keep on our own server and refresh every month. The lookup itself does not call any outside service.
Can I look up IPv6 addresses?
Yes. Enter the full IPv6 address. Location data for IPv6 can be less precise than for IPv4, because providers often assign large IPv6 ranges to a whole region.
Why can I not look up 192.168.x.x or 10.x.x.x?
Those are private addresses that exist inside many separate networks at once, so they have no public owner or location. The same goes for loopback, link-local and other reserved ranges.
Does the result show whether an IP is a proxy or VPN?
Not directly. The organization shows the type of network: a hosting company suggests a server, VPN or datacenter proxy, while a broadband or mobile provider suggests a home or phone connection. The lookup does not keep a list of known proxies.
In practice
An IP lookup connects a public address with network registration and approximate location information. It is a useful troubleshooting tool for developers checking their own network or a proxy exit, but it should not be mistaken for a map of a person’s home.
What an ASN tells you
An autonomous system number identifies a network that announces IP address ranges. The associated organization may be an ISP, cloud provider, business network or transit operator. Network ownership and the person using an address are different things; an ASN is not a user identity.
Why city results can differ
IP databases use registration, routing and other signals to estimate location. Mobile networks, VPNs and enterprise networks may use shared routing points far from a device. Two credible databases can report different cities for the same address, and neither provides reliable street-level information.
A domain lookup is a snapshot
A hostname can resolve to more than one address, with results changing by DNS configuration or region. If you enter a domain, record which address was returned. That is the address being described, not necessarily every possible server the domain could use.
Use the result in context
To verify your own proxy’s exit, first make a request through that proxy and obtain the observed public IP. Then look it up and compare the reported country with the selected location. Also check the destination application’s displayed country; do not treat geolocation alone as a guarantee of localized content.
Questions on this topic
Can an IP lookup identify a person?
No. Network and location databases do not establish the identity or home address of an individual user.
Is the city accurate to the street?
No. City fields are approximate and may identify a regional network hub.
What happens with IPv6?
IPv6 addresses work too; their registration and location are also estimates, not personal identity data.
