How to use the lookup
- Open the page. Your public IP is fetched and displayed automatically.
- Read the location details - country, region, city and the organisation that owns the address block.
- Treat the city as a hint, not a fact. The accuracy section below explains why.
This is one of the few tools on OmniTool that must contact an outside service: your browser cannot see its own public IP without asking someone. The request goes from your browser directly to a public IP information API.
Public and private addresses
Almost every home and office network uses network address translation. Your devices get private addresses from a reserved range - 192.168.0.0/16, 10.0.0.0/8 or 172.16.0.0/12 - and your router rewrites their traffic to use a single public address on the way out.
So the address shown here identifies your router or your carrier's gateway, not your individual device. Everyone on your network shares it, which is why a site that blocks an IP address can block an entire office or, in the case of carrier-grade NAT, an entire town.
How accurate is IP geolocation?
There is no location field in the IP protocol. Geolocation databases are built by inference: registry records showing which organisation owns a block, latency measurements between known points, ISP-published routing data, and user corrections. The result is good at the top level and unreliable at the bottom.
| Level | Typical accuracy |
|---|---|
| Country | 95-99% on fixed broadband. This is the level businesses can actually rely on. |
| Region or state | Roughly 75-85%. |
| City | Around 50-75% on broadband, and often much worse on mobile networks, where a single gateway may serve subscribers hundreds of kilometres apart. |
| Street or postcode | Not meaningfully possible from an IP address alone, whatever a marketing page claims. |
Several things break it entirely: VPNs and proxies show the exit server's location; satellite and some mobile providers route through distant gateways; corporate networks may egress through a head office in another country; and coordinates for an address with no better data often default to the geographic centre of the country, which has caused real harm to the people who happen to live there.
Who sees your IP address, and what they can do with it
Every server you connect to sees it - that is how the response finds its way back. So does every site whose ads, fonts, analytics or embedded videos your page loads.
What that gives them: a rough location, your ISP, and a semi-persistent identifier for rate limiting, fraud scoring and geographic content rules. What it does not give them: your name, your address, or access to your computer. Only your ISP can map an address to a subscriber, and in most jurisdictions that requires legal process.
If you want to change what sites see, a reputable VPN routes your traffic through its own server so sites see that address instead. Tor goes further at a substantial cost in speed. Note again that neither hides your browser fingerprint.
IPv4 and IPv6
IPv4 addresses are four numbers up to 255, such as 203.0.113.42 - about 4.3 billion in total, which ran out years ago. IPv6 uses eight groups of hexadecimal digits, such as 2001:0db8:85a3::8a2e:0370:7334, providing an address space large enough that exhaustion is not a concern.
You may see either here, or both. Because IPv6 gives every device a globally routable address rather than hiding it behind NAT, an IPv6 address can identify a single device rather than a whole household - which is why privacy extensions that rotate the address are enabled by default on most operating systems.
Frequently asked questions
Because IP geolocation infers location rather than measuring it. Mobile networks, VPNs, corporate routing and satellite links all commonly report a location far from the user. Country is usually right; city frequently is not.
Not from the address alone. Only your ISP holds the subscriber record, and disclosing it normally requires a court order. Public databases resolve to a city at best.
Usually yes. Most residential connections use dynamic addressing, so the address changes when your router reconnects or on a schedule set by the ISP. Static addresses are typically a business option.
We do not store it. Displaying it requires asking a third-party API, which necessarily sees the request - that is unavoidable for any tool of this kind, and it is listed as an exception in our privacy policy.
Use a VPN, or Tor for stronger anonymity. Both replace the address sites see with one belonging to the service. Neither changes the other identifying details your browser exposes.
What this tool sends, and what it does not
Most OmniTool utilities make no network request at all. This one is an exception, and it is worth being precise about it: to do its job, this tool contacts a public IP information service, which necessarily sees your IP address. That request goes directly from your browser to that service — we do not proxy it, and we never receive a copy of it or of the response.
Nothing else on this page is transmitted, and we keep no record of what you looked up. The privacy policy lists every tool on the site that makes an outside request, along with what our advertising partner collects.
