Approximate location
Country and city, usually accurate to within ~25 km. Derived from network registries, not your device's GPS — which is why VPNs can change it.

Network fundamentals
What your IP
What your IP
address actually
reveals.
An IP address is more than a number. It's a return label every server you talk to uses to find you again — and along the way it leaks plenty about the network you came in on.
ISP & network
The provider routing your traffic, the autonomous-system number, and whether you're on residential, mobile, hosting, or VPN infrastructure.
ISP name
ASN
Network type
VPN signals
Browser fingerprint
User-agent, language, screen, GPU — combined into a signature that follows you across sessions even when cookies are cleared.

A boring page
A boring page
that solves
real problems.
Check My Setup is a single, shareable URL. Built for the moments when "what's your IP?" should take five seconds, not five screenshots — and for the people who need to prove their setup is the way they say it is.
Send your support agent the exact picture of your connection in one link.
Region, ISP, browser, OS, and time of detection — all on one page they can scroll, without asking you to type things back and forth.
Confirm the country you're working from before a contract or transfer goes through.
Useful for compliance, geo-restricted SaaS, or proving to a client that your traffic is leaving from the country you said it would.
Quickly verify your VPN is doing what it promised — or notice when it isn't.
Spot DNS leaks, the wrong exit node, or an unexpectedly residential IP. Recheck after every tunnel change in seconds.
See, in plain English, what every site you've ever opened has been reading about you.
No marketing pitch. No upsell. A static page that shows you the thing and gets out of the way.
IP lookup
Look up
Look up
any IP address.
Paste an IPv4 or IPv6 address and get location, ISP, ASN, and whether it looks like residential, mobile, hosting, or anonymizer traffic.
IP geolocation explained
Accurate —
Accurate —
but not a GPS.
IP geolocation maps your address to a database of network registries. It's reliable at country level, decent at region, vague at city, and unreliable at street level.
For an accurate fix you need GPS, Wi-Fi triangulation, or a confession from the user. For "are they in the right country before we serve them this stream?" — IP is fine.
| What you'll get | Typical accuracy |
|---|---|
| Country | ~99% |
| Region / state | ~85% |
| City | ~55% |
| Postal code | ~25% |
| Street address | — never |
| Through a VPN | Exit node, not you |
FAQ
Frequently
Frequently
asked questions.
The short version: we run as a static page, we don't log your visit, and the data you see is the same data every other website you open is already reading from your browser.
No. Check My Setup runs as a static page in your browser. The detection is read from your own browser session — nothing about you is written to a database, analytics pipeline, or cookie. The page has no server-side component.
Yes, with one caveat. You're seeing the IP of the network you exited on the way to us. If you're behind a corporate proxy, a VPN, or a privacy relay, that's the address sites see — not your device's local IP, which servers can't reach directly.
"Copy share link" encodes your setup data as a Base64 hash in the URL — nothing is sent to our servers. The recipient opens the link and sees a snapshot of exactly what you shared. Perfect for support tickets, compliance screenshots, or onboarding checks.
The detection logic runs entirely in your browser as a static HTML + JS page. You can inspect the full source in any browser's developer tools. There's no hidden server-side detection — what you see in DevTools is everything.
Country accuracy is around 99%, city accuracy is closer to 55%. We map your IP through public network registries — we don't ping your GPS, Wi-Fi, or anything on your device. If you're on mobile data, expect the city to be wrong fairly often as carriers aggregate traffic through regional hubs.
Three usual suspects: a VPN exit node located in a different city, a mobile carrier that aggregates traffic through a regional hub, or an ISP that hasn't updated its registry entry in a while. Try toggling your VPN on/off to see the difference immediately.
An Autonomous System Number (ASN) is a unique identifier assigned to each network operator — your ISP, a CDN like Cloudflare, or a hosting provider. It tells you who owns the block of IP addresses your address belongs to. Useful for verifying whether you're on residential, commercial, or datacenter infrastructure.
It means your IP isn't flagged in known VPN provider, proxy, or datacenter IP lists. It doesn't guarantee you aren't using a VPN — residential exit nodes from newer VPN providers often look clean in these databases. The check is a strong signal, not a certainty.
Yes. The IP lookup section above accepts any public IPv4 or IPv6 address and returns location, ISP, ASN, and connection-type information. It won't work on private/local addresses (192.168.x.x, 10.x.x.x, etc.) as those aren't routable on the public internet.
Your browser exposes information like user-agent, screen resolution, language, and device type through standard JavaScript APIs — no permissions required. This tool reads those values and shows them to you, but every website you visit can silently collect the same data. There's no way to opt out short of using a privacy browser.
The share link encodes your setup snapshot as a Base64 hash appended to the URL (#s=...). The data lives entirely in the URL fragment — it's never sent to our servers. Anyone who has the link can read the encoded data, so only share it with people you trust. The link is a point-in-time snapshot; your current setup may have changed since it was generated.
We're building a small JSON API for the same detection you see on this page, plus a one-line embed for status pages. It's currently in private beta — drop us a line if you'd like to try it early.
