What is a public IP address?
The address your internet provider assigns to your connection. Every website you open sees it, because that is where it sends the page back to.
Private and public IPs
Your phone, laptop and smart TV each get a private IP (like 192.168.1.5) inside your home network. When they go online, your router shares one public IPv4 address assigned by your provider, and that is the address websites see and reply to. On mobile data, many customers can share the same public IPv4 address through carrier-grade NAT.
IPv4 and IPv6
IPv4 addresses look like 203.0.113.42 and are running out, so providers now also hand out IPv6 addresses such as 2001:db8::1. With IPv6, each device can get its own public address. Most connections in 2026 use both, and a website sees whichever one your device chose for that visit.
What else your browser reveals
With every page request, your browser sends headers such as User-Agent and Accept-Language. Scripts on the page can then read your screen size, timezone, language and CPU core count. None of these identify you on their own, but together they can form a fingerprint that helps recognise the same device across sites and over time.
Why it is worth checking
Sites use this data for good reasons: showing the right language, blocking suspicious logins, serving pages that work on your device. The same signals also power ad tracking. Run this check before and after turning on a VPN to confirm it actually changes your IPv4, IPv6, provider and location.
What each field means
Where every value in your report comes from, how websites use it, and how much it reveals.
| Field | Source | What it shows | How websites use it | Privacy impact |
|---|---|---|---|---|
| IP address (IPv4 and IPv6) | Network | The public addresses your connection uses. Many connections have both an IPv4 and an IPv6 address. | Routing replies, localisation, rate limiting, fraud checks, analytics. | HighReveals your provider and approximate city. With a VPN or Tor, sites see the exit server's IP instead. |
| ISP and organization | IP lookup | The company that owns your IP range: an ISP, mobile carrier, employer or cloud provider. | Fraud scoring, business targeting, spotting VPN and hosting traffic. | MediumCan reveal your employer on a work network. Hidden by a VPN. |
| ASN | IP lookup | Autonomous System Number, the global ID of the network your IP belongs to. For example, AS13335 is Cloudflare. | Routing analysis, separating home connections from data-centre traffic. | LowTechnical data, rarely used on its own. |
| Location | IP lookup | Approximate city, region and country. | Language, currency, regional pricing, legal compliance. | MediumArea-level only, never a street address. Hidden by a VPN. |
| User Agent | Header | Browser, version, operating system and device type. | Serving compatible pages, analytics. | MediumPart of most fingerprints. Chrome and Edge now send a reduced version; detail moves to Client Hints. |
| Screen and viewport | JavaScript | Display size and the visible browser area in pixels. | Responsive layouts, ad sizing. | MediumUnusual sizes make a device easier to single out. |
| Pixel ratio and colour depth | JavaScript | Display density (2x on most high-resolution screens) and colour bits. | Serving sharp images. | LowMinor fingerprinting signal. |
| CPU cores and memory | JavaScript | Logical CPU cores and approximate RAM, rounded by the browser. | Adapting heavy apps and games to the device. | MediumAdds detail to fingerprints, especially uncommon core counts. |
| Timezone | JavaScript | Your device timezone, for example Asia/Kolkata. | Showing local times, fraud checks. | MediumA mismatch with your IP location can reveal VPN use. |
| Language | Header and JavaScript | Preferred languages, for example en-IN, en, hi. | Content localisation. | LowUncommon language combinations are more identifying. |
| Cookies | JavaScript | Whether your browser accepts cookies. | Deciding whether logins and sessions can work. | LowSimple on/off signal. |

How this tool works
What happens between opening this page and seeing your report.
Your browser connects
When the page loads, your browser connects to our server. Like every website, we see your public IP and request headers such as User-Agent and Accept-Language.
We identify browser and network
Our server reads your IP (verified through Cloudflare when present) and parses your User-Agent to identify browser, operating system and device type.
Location lookup
Our server sends only your IP address (no browser or device data) to ip-api.com, which returns ISP, organization, ASN and approximate location. To avoid repeat lookups, the result is cached for up to 6 hours against a hashed version of your IP.
Your browser adds the rest
To show both IPv4 and IPv6, your browser also asks ipify.org directly (one IPv4-only and one IPv6-only request); ipify sees only the address used for each request. Screen size, timezone, languages and CPU cores are read by JavaScript and stay in your browser.
Nothing is saved
This tool does not save your results or build a profile. Only a hashed rate-limit counter (expires within 24 hours) and a cached location lookup (up to 6 hours) are kept temporarily.
What this tool does, and what it doesn't
A plain list, so you know exactly what to expect.
This tool does
- Show your public IPv4 and IPv6 addresses
- Identify your provider, ASN and organization
- Estimate your city and region (approximate)
- Detect browser, operating system, screen and timezone
- Flag hosting or relay networks and timezone mismatches
- Offer an optional WebRTC leak test
This tool does not
- Reveal your street address
- Bypass VPNs, Tor or relays
- Save your results or build a profile
- Track you across visits
- Require an account
- Send your device details to our server
Where your data goes
To show ISP, ASN and approximate location, our server sends your IP address, and nothing else, to ip-api.com. To show both IPv4 and IPv6, your browser also asks ipify.org directly (one IPv4-only and one IPv6-only request); ipify sees only the address used for each request. Screen, timezone, language and other device details are read by JavaScript and stay in your browser. Like any website, our server and CDN may keep standard access logs, as described in our privacy policy.

Why your results might look unexpected
The six surprises people ask about most, and what each one means.
VPN on, but your real location shows
If your VPN is working, you'll see the VPN server's IP and location. If you still see your own provider, the VPN may be disconnected, split tunnelling may exclude your browser, or the page loaded before the VPN connected. Select Refresh to check again.
The city is wrong
IP geolocation is approximate. The country is usually reliable, but the city often reflects where your provider registers or routes its network, not where you are sitting.
Provider shows Amazon, Google, Akamai or Cloudflare
Your traffic is passing through a relay or VPN such as iCloud Private Relay, Cloudflare WARP, a corporate VPN or a proxy. The IP belongs to that service, not your home provider.
A long address with colons
Your provider and device support IPv6, the newer internet protocol. It works the same way for browsing; the addresses are simply longer, for example 2001:db8:85a3::8a2e:370:7334.
Mobile data shows a distant city
Mobile carriers route traffic through a small number of regional gateways, so your IP usually geolocates to the gateway's city rather than your nearest tower.
Your IP changes between checks
Common causes are a connection switching between IPv4 and IPv6, iCloud Private Relay or a VPN rotating exit servers, or a mobile network routing you through different gateways. It is normal and not a security problem.
Questions about your IP and browser
Is the location shown my exact address?
No. IP geolocation estimates the area served by your provider's network, not your street address. The country is usually right; the city can be off by tens or hundreds of kilometres, especially on mobile data. A website can only get your precise position through your browser's location permission, which always asks you first.
Why do I have both an IPv4 and an IPv6 address?
Most providers now run both protocols side by side, which is called dual stack. Your device picks one for each connection, usually IPv6 when it is available, and a website sees whichever one was used. That is why this tool checks both and shows each one separately.
What is a User Agent?
A text string your browser sends with every request to identify its name, version, operating system and device type. Your own User Agent appears in the Browser and OS section above. Chrome and Edge now send a reduced version with frozen OS details, so sites increasingly use User-Agent Client Hints, which this tool also reads when your browser supports them.
Can someone find me from my IP address?
Not directly. Your IP reveals your provider and an approximate area, not your name, phone number or home address. Only your provider can link an IP to a customer account, and it normally does that only in response to a legal request. A VPN or Tor replaces your IP with theirs for the sites you visit.
How do I check if my VPN is working?
Note your IPv4, IPv6 and provider here, connect your VPN, then select Refresh. A working VPN shows different addresses, the VPN company or a hosting network as provider, and a location that matches the server you chose. If your IPv6 address stays the same while IPv4 changes, your VPN is leaking IPv6. Also check the timezone result and run the WebRTC leak test.
Is my data stored?
This tool does not save your results or build a profile. Only a hashed rate-limit counter (expires within 24 hours) and a cached location lookup (up to 6 hours) are kept temporarily. Like any website, our server and CDN may keep standard access logs, as described in our privacy policy.
Why does this tool need JavaScript?
Your IP, provider and User Agent are read on our server, but this page uses JavaScript to request and display them. Screen size, viewport, timezone and CPU cores are only visible to JavaScript, and they stay in your browser.
