Your IP address and everything a site sees about you
Click the button — in a second we'll show your IP address, operating system, browser, location, internet provider and the digital fingerprint your browser hands to every website. We store nothing.
Data is read right inside your browser and at the network edge — we do not store it or pass it to third parties.
Enter someone else's domain or IP address — we'll show where it's hosted, which provider or host owns it and which web server answers. We store nothing.
Browser fingerprint
What the tool shows
Two data sources: what your browser reports, and what is visible from your network connection — together they form your digital footprint.
Device and browser
Operating system and its version, browser, device type, screen resolution, CPU cores and memory — from the data your browser hands to every site.
IP and location
Public IP address (IPv4 or IPv6), country, region and city, your internet provider and its autonomous system number (ASN) — from the network data.
Connection and privacy
HTTP and TLS protocol version, a proxy/VPN flag, timezone, language and Do-Not-Track mode — how protected you are while browsing.
Who uses My IP Address — and why
Three everyday situations where knowing your IP and digital fingerprint saves you time or protects your privacy.
Privacy audit before sharing your screen
Before you join a video call, demo a product, or stream your desktop, click Check — in a second you see exactly what information is visible. Public IP, location, internet provider, and your browser's fingerprint are all exposed automatically the moment any webpage loads.
If the result shows a city that reveals your home address, or a proxy/VPN flag you did not intend, you can switch networks or adjust settings before the session. No guesswork, no surprises mid-demo.
VPN verification — confirm your tunnel is working
A common frustration: you enable a VPN, assume it is protecting you, and never verify. Click Check with your VPN on — if the IP and location still show your real city and the proxy flag says "Direct connection", your tunnel has failed, likely a DNS or routing leak.
Run the check again after reconnecting. The Proxy/VPN field and the TLS pill together tell you whether traffic is routed through the VPN and whether you are negotiating a modern TLS 1.3 session — a quick pass/fail in under two seconds.
Web development — test IP detection in your app
Building a geo-fencing feature, a rate limiter, or a fraud-detection rule? Use "Check a domain or IP" tab to see how our edge resolves any target host — its IP, hosting provider, ASN, and whether the web server responds. Compare different CDN nodes or staging environments before deploying.
On the user-side tab, check your own fingerprint from the test environment — screen resolution, hardware concurrency, timezone, and language locale — so you can replicate realistic user sessions in your QA suite. Pair the result with our Website Security Check to cover HTTPS configuration as well.
Frequently asked questions
What is a public IP address?
A public IP address is the unique numeric label your internet service provider (ISP) assigns to your router. It identifies your network on the global internet the same way a postal address identifies a building. Every device behind that router shares the same public IP, while each device gets its own private IP for communication inside the local network. Our tool shows your public IP — the one every website sees when you connect.
How often does my IP address change?
It depends on your ISP and contract. Consumer broadband typically uses dynamic IPs that change each time your router reconnects — often every 24 hours, or after a power cycle. Business plans and some fibre packages offer static IPs that stay fixed indefinitely. Mobile carriers reassign IPs very frequently, sometimes per session. Click Check again after restarting your router to see whether your IP changed.
Can a website see my home address or physical location?
No. A website sees your public IP and can map it to an approximate city or region using a GeoIP database — but this geo data points to your ISP's infrastructure address, not your home. The accuracy is typically city-level at best; rural areas can show the nearest large city. Our tool applies the same technique: the location shown is an estimate, not your GPS coordinates. Your exact address cannot be obtained from an IP address alone without a court order to the ISP.
What is a browser fingerprint and how is it different from an IP?
A browser fingerprint is a profile built from attributes your browser freely shares — screen resolution, operating system, installed fonts, hardware concurrency, timezone, language, and more. Unlike an IP, it does not change when you reconnect or switch networks, and it persists across incognito/private windows because it reads device characteristics rather than stored identifiers. Combined with your IP, it makes you highly identifiable. Our tool shows the fingerprint data in the "Browser fingerprint" panel after you click Check.
How do I hide or change my IP address?
The three main methods are: VPN (routes all traffic through a remote server and replaces your IP with the server's IP — most practical for everyday use), Tor browser (chains multiple volunteer relays for stronger anonymity but slower speeds), and proxy server (similar to VPN at the application level). After enabling any of these, use the Check button to confirm the Proxy/VPN pill turns amber and the displayed IP and location differ from your real connection. If they still match, the VPN has a leak.
What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses in dotted-decimal notation (e.g. 203.0.113.45) — the format you probably recognise. There are only about 4.3 billion possible IPv4 addresses, and the pool is exhausted, so ISPs now also assign IPv6 addresses, which use 128 bits and look like 2001:db8::1. IPv6 provides a practically unlimited address space. Many ISPs run dual-stack, giving you both; the tool displays whichever your device used to reach the Cloudflare edge.
Why does my detected location show the wrong city?
GeoIP databases map IP ranges to the address on record for the network owner — usually a data centre or ISP office, not the subscriber's home. If your ISP's infrastructure is in a different city than you, or if you are on mobile data routed through a regional hub, the displayed city may be off by hundreds of kilometres. This is a fundamental limitation of IP geolocation, not a tool error. For precise location, a device must share its GPS signal explicitly.
What is an ASN (Autonomous System Number)?
An Autonomous System (AS) is a collection of IP prefixes under the control of one organisation — an ISP, cloud provider, or large enterprise. Each AS is assigned a globally unique Autonomous System Number (ASN) by a regional internet registry. When you see "AS15169 Google LLC" next to your provider info, it means the IP belongs to Google's network. ASNs help security tools distinguish residential users from VPN servers, hosting companies, or known Tor exit nodes — which is part of how the proxy/VPN detection in this tool works.
Is browser fingerprinting legal?
The legality depends on jurisdiction and purpose. In the EU, ePrivacy Directive and GDPR guidance generally require user consent for fingerprinting used for tracking or profiling — similar to cookies. In the US, there is no single federal law, though state-level statutes like the CCPA give users rights over data collected about them. First-party fingerprinting for fraud prevention or security (without cross-site tracking) is generally considered acceptable. Our tool does not store any fingerprint data — it reads values client-side and displays them to you only.
How do I check the IP address of a website or domain?
Switch to the "Check a domain or IP" tab on this page, type the domain name (e.g. example.com) or an IP address, and click Check. The tool performs a DNS lookup, maps the resolved IP to a hosting provider and ASN via a GeoIP database, checks for a PTR (reverse DNS) record, and sends a single HTTP request to see whether the web server responds and whether HTTPS is active. Results appear in a few seconds. This is useful for verifying where a competitor or partner site is hosted, or debugging DNS propagation after a migration.
Need a website that treats user data with care?
HTTPS and modern TLS, correct security headers, an honest cookie banner and privacy compliance. We'll check your website across these areas for free.
