What this tool does
It shows the public IP address your traffic is arriving from, along with what that address reveals: the country, the approximate region, the network operator announcing it, and the details of the connection your browser negotiated.
There is no lookup involved. Your address is part of every request your browser makes — it has to be, or nothing could be sent back — so this page simply reads it from the request that fetched the page and prints it. Nothing is asked of any other service.
Common uses
- Adding your address to an allowlist — a database firewall rule, an SSH
AllowUsersrestriction, an office IP exception. - Checking whether a VPN or proxy is actually carrying your traffic, and where it exits.
- Confirming a home connection's address before setting up dynamic DNS.
- Working out whether you have IPv6 at all — if the address below starts with a number and dots, this connection reached us over IPv4.
- Giving support the address their logs will show.
Your IP address is not your identity
The location shown here comes from a registry of which network operator holds which address block, not from your device. It is usually right about the country and frequently wrong about the city — routinely by tens of kilometres, and sometimes by the entire width of a country when an operator routes a region through one exchange. It is not GPS, it does not come from your device's location services, and no website can obtain those without asking you first.
If you are on a home or office network, this address belongs to your router, not your
computer. Every device behind it shares the same public address through NAT, so what a remote
server sees is your household or your building, not your laptop. The 192.168.x.x
or 10.x.x.x address your machine holds internally is not visible here and cannot
be — those ranges are not routable and never leave your network.
Why the address may change
Most residential connections receive a dynamic address from the provider, which can change
when the router reconnects, and does so unpredictably — hours for some providers, months for
others. Mobile networks change it far more often, and a carrier-grade NAT deployment can put
thousands of subscribers behind a single address in the 100.64.0.0/10 range.
That is why a firewall rule pinned to a home IP eventually stops working, and why an
allowlist is a poor substitute for authentication.
Worth knowing
IPv6 changes the shape of this. A device on IPv6 generally holds a globally routable address of its own rather than sharing one through NAT, so the address shown is more likely to identify a single machine — which is precisely why privacy extensions (RFC 8981) exist, and why operating systems rotate the interface portion of the address, typically daily. If you see a long hexadecimal address above, you are on IPv6; a site reached over IPv4 would show four numbers separated by dots, and many networks will give you a different address for each depending on which the site supports.
Frequently asked questions
Why does the city shown not match where I am?
Because it was never measured. The location comes from a registry mapping address blocks to the network operator that holds them, and the coordinates attached to a block describe where the operator registered it — often a regional exchange or a head office rather than your street. Country accuracy is high; city accuracy is commonly quoted around 50–80% within 50 km and is far worse on mobile networks, where a single block can cover a whole country. Nothing on this page reads your device’s location, and no site can without a permission prompt.
Why is my IP different on my phone and my laptop on the same wifi?
On IPv4 it should not be — everything behind one router shares its public address through NAT, and the difference usually means the phone dropped to mobile data. On IPv6 it is expected: each device holds its own globally routable address from the same prefix, and privacy extensions (RFC 8981) rotate the second half of it, typically once a day, so even one device sees its address change. A site reachable over both protocols will also show you a different address depending on which your browser chose.
Can I find someone’s physical address from their IP?
No. The best a public database gives is a city-level guess that is often wrong, and the operator’s own records — which do link an address to a subscriber — are disclosed only to a legal request. Carrier-grade NAT makes it worse still: a mobile operator may put thousands of subscribers behind one address, so even the operator needs the exact timestamp and source port to identify which. Services claiming to locate a person from an IP are selling the same registry guess you can see here.
Does hiding my IP with a VPN make me anonymous?
It moves the problem rather than removing it. Sites then see the VPN’s exit address instead of yours, and your provider sees the destination instead. But an IP is only one of many ways to recognise a browser: cookies, logins, and fingerprinting from fonts, canvas rendering and screen metrics all survive a change of address. A VPN is useful for hiding your traffic from the local network and your address from a site — it is not anonymity, and a provider that keeps logs simply relocates the record.
