IP address lookup
Look up any public IP address to see its approximate city, country, provider, network (ASN), time zone and currency.
The address is sent to a third-party lookup service (ipwho.is) when you press the button. Locations are approximate.

How to use the ip address lookup
What it calculates and when to use it
Looks up any public IPv4 or IPv6 address and shows its approximate city, region and country, the internet provider that uses it, the network number (ASN), the time zone and the local currency. Use it to check where a visitor, a server or an email came from, to confirm a VPN is working, or to see who runs a network.
How to use it, step by step
- Type an IP address into the box, or leave it empty to look up your own.
- Press “Look up”.
- Read the location, network and region details in the cards below.
- Press “Copy result” to copy a one-line summary.
What each input means
- IP address – An IPv4 address such as 8.8.8.8 or an IPv6 address such as 2001:4860:4860::8888. Leave empty to use your own address.
How to read the results
- Location – City, region, country, continent, postal code and coordinates the address is registered or routed to.
- Network – The internet provider, the organisation, the ASN and the domain behind the address.
- Region details – Time zone, local time, currency and international calling code for that place.
The formula
No calculation. The address is matched against a geolocation database run by the lookup service ipwho.is. Databases combine registry records, routing data and measurements, so each result is an estimate.
A worked example
Looking up 8.8.8.8 shows Google LLC as the provider, AS15169 as the network and a location in California, because the address belongs to Google’s public DNS service.
Assumptions and limits
- The location is the best estimate of where the network is based, not where the device is. It is often only right to the city or region.
- Private addresses such as 192.168.1.1 and 10.0.0.1 do not exist on the public internet, so they cannot be located.
- The address is sent to ipwho.is when you press the button. It is not sent before.
Common mistakes
- Expecting a street address. An IP address can never show a house or a person.
- Looking up a private address such as 192.168.0.10 and expecting a result.
- Treating a VPN or mobile-network address as the user’s real location, because it shows the VPN server or the carrier’s hub.
Frequently asked questions
Can an IP address show someone’s exact location?
No. It points to a provider’s network, usually accurate to a city or region. Only the provider knows which customer used an address, and it shares that only under legal process.
Why is the location wrong?
Databases are estimates. Mobile networks, VPNs, company networks and satellite internet often route traffic through a hub in another city or country.
Is looking up an IP address legal?
Yes. IP addresses are public information used by every website and server to talk to each other.
Does this tool work for IPv6?
Yes. Paste an IPv6 address and it is looked up in the same way.
Is the address stored?
No. It is sent to the lookup service when you press the button and is not stored by this page.
