What this tool shows you
Click once and the tool reports your public IP address along with the metadata associated with it: your internet service provider, the approximate city and country, timezone, postal code, coordinates, and the ASN (Autonomous System Number) that owns the address block. You can also type any other IP address into the field to look it up instead.
Public IP versus local IP
Every device on a home or office network has two different addresses, and confusing them is the most common misunderstanding in networking.
| Local IP | Public IP | |
|---|---|---|
| Looks like | 192.168.1.x or 10.0.0.x | Assigned by your ISP |
| Assigned by | Your router | Your internet provider |
| Visible to | Only devices on your network | Every website you visit |
This tool shows your public IP — the one the internet sees. To find your local IP you would check your device's network settings, since a website has no way to read it.
How IP geolocation actually works
An IP address does not contain a location. Geolocation works by looking the address up in databases that map IP ranges to the physical infrastructure of the ISP that owns them. That is why results are approximate: you are being located to your provider's regional equipment, not to your street.
In practice this means the city shown may be the nearest large hub rather than your actual town, and users on a VPN or mobile network will see the location of the VPN exit node or the carrier's gateway. This is a limitation of every IP geolocation service, not a flaw in one particular tool — no service can derive your home address from an IP alone.
What an ASN tells you
An Autonomous System Number identifies the organisation that controls a block of IP addresses — typically an ISP, a cloud provider, or a large company running its own network. Seeing something like "AS15169 Google LLC" tells you the address belongs to Google's infrastructure rather than a residential connection. This is genuinely useful when you are checking whether traffic came from a data centre, verifying a VPN endpoint, or investigating the origin of a suspicious connection.
When people actually need this
- Troubleshooting: confirming which address a service sees when a firewall or allowlist is not working.
- VPN verification: checking that your VPN is actually routing traffic and reporting a different location.
- Server checks: finding out where a host is physically located and who operates its network.
- Security investigation: tracing the network origin of an unexpected login or email header.
A note on privacy
Looking up an IP tells you about a network, not a person. Your IP is visible to every site you visit by design — it is how responses find their way back to you. What it does not reveal is your identity, name, or precise address. For more, read what your IP address actually reveals and understanding ASNs and IP networks.
This is the one tool here that necessarily makes an outbound request: looking up an address requires querying a geolocation API. The addresses you look up are not logged on our end.
Frequently Asked Questions
Why does my IP show the wrong city?
Geolocation maps your address to your ISP's regional infrastructure, not your street. If your provider routes traffic through a hub in another city, that is what appears. VPN users see their exit node's location.
Can someone find my home address from my IP?
No. An IP reveals your ISP and approximate region. Linking it to a person or address requires legal process with the ISP — it is not something a website can do.
What is an ASN?
An Autonomous System Number identifies the network operator that owns a block of IP addresses — usually an ISP, cloud provider, or large company.
Can I look up someone else's IP address?
Yes, type any IP into the field. This is useful for checking where a server is hosted or verifying a VPN endpoint, though it returns network data, not personal information.
