IP Lookup

Find out what an IP address is registered to: approximate location, organization, ISP, autonomous system number (ASN) and timezone. You can also reveal your own public IP address with one click.

Look up a public IP address

IP address (IPv4 or IPv6)

What this tool does

The IP Lookup tool sends the address you enter to the ipwho.is API from your browser. The API returns the registration details it has on file: country, region, city, coordinates, postal code, ASN, the organization that owns the address range, and the timezone.

For your own public IP, the address itself is detected with api.ipify.org first, and the same detail lookup is then performed.

How it works

Your browser calls ipify to learn your public IP (or you type an address).
Your browser calls the ipwho.is API with that address.
ipwho.is queries IP registration databases and returns the details shown.
This page renders the results and labels the source.

Limitations & transparency

IP geolocation is an estimate. Databases map an address to where it is registered — that can be a datacenter, an ISP hub, or a different country than the person using it. A VPN, carrier-grade NAT or corporate proxy will show their location instead of yours. The tool cannot be more accurate than the database behind the API.

Your looked-up address is sent by your browser to ipwho.is (and to ipify when detecting your own). Neither submits addresses to this site (it is a static page with no backend), and this site stores no results. See the Privacy Policy.

Key terms to understand

Public IP address: The address that other servers see when your device talks to the internet. It is assigned by your ISP and shared by your router (and often by all devices behind it).
IPv4 vs IPv6: IPv4 uses 32-bit addresses (like 8.8.8.8) and is running out of room. IPv6 uses 128-bit addresses (like 2606:4700:4700::1111) and is its successor. Both are valid inputs here.
ASN (Autonomous System Number): A number that identifies an organization that controls a block of IP addresses and routes traffic for it — for example your ISP.
ISP / organization: The company that owns and operates the address range the IP belongs to. The API reports the registration, which is usually your ISP.
Timezone: The timezone most commonly associated with the registered location of the address.

FAQ

Why does my IP show a city I've never visited?

IP databases map addresses to registered locations, and ISPs often register blocks far from their customers. This is normal — the estimate points at the registration, not your doorstep.

Why do different lookup sites disagree about my location?

Each provider licenses different databases and updates them on different schedules, so estimates vary. That is why every result here carries its source label.

Can this tool find a person from an IP?

No. It returns registration data only (region, ISP, ASN). It does not reveal who is using the address, and public databases cannot reliably do that either.

Should I be worried that the tool sees my IP?

Every website you visit sees your public IP by necessity of how the internet works. The lookups here (ipify, ipwho.is) are the only recipients, and this static site does not store anything.
