Device and browser
Operating system, browser, device type, screen, CPU cores and memory — what your browser hands to every website.
Your IP Address and Digital Footprint
See what the internet knows about you right now: your public IP address, city, ISP, network (ASN) and browser fingerprint. The second tab lets you look up any domain or IP address.
We don't store your IP address or share it with anyone — location is resolved from a database on our own server.
Your browser fingerprint is read right on your device. We don't log, store or share your IP address: city and ISP are resolved from a database on our own server.
What the tool shows
Two data sources: what your browser reports and what your network connection reveals. Together they make up your digital footprint.
IP and location
Your public IP address (IPv4 or IPv6), country, region and city, internet provider and autonomous system number (ASN).
Connection and privacy
HTTP and TLS versions, VPN signs, WebRTC leaks, time zone, languages and Do Not Track.
When an IP check comes in handy
Before sharing your screen
Before a call or a stream, make sure your home city and ISP aren't visible — every website receives this data the moment it loads.
Make sure your VPN works
Turn on your VPN and check again: your IP, country and ISP should change, and "Network type" should show a data center. If the address stays the same, the tunnel isn't working.
Development and sysadmin work
The "Look up a domain or IP" tab shows where a domain points, who hosts it, its PTR record and whether the server answers over HTTPS — handy after a migration or a DNS change.

What an IP address is and why you should know yours
An IP address is your device's unique network identifier on the internet. Every website you connect to sees your approximate region and ISP through it, and ad networks use it for tracking. Knowing your IP helps when setting up access, troubleshooting your network and checking how anonymous you really are online.
What the internet sees about you without a VPN
Even without signing in, your browser automatically shares a surprising amount of data. Together it forms a "digital fingerprint" that can single you out from other visitors — even without cookies and in incognito mode.
- Your public IP address, city, ISP and network number (ASN).
- Your time zone, system language and preferred languages.
- Your operating system, browser, device type and screen resolution.
- Your local IP address via WebRTC — sometimes even with a VPN on.
How to find the IP address of a website or domain
Open the "Look up a domain or IP" tab and enter a site address such as example.com. The tool runs a DNS query, shows the IPv4 and IPv6 addresses, the country and hosting provider from the geolocation database, and the reverse DNS (PTR) record, then sends one HTTPS request to check whether the web server responds and which software it runs. It's a quick way to find out who hosts a site or to confirm that DNS already points to a new server.
What a WebRTC leak is
WebRTC powers video calls and data transfer directly in the browser. While setting up a connection it can expose your local — and sometimes your real public — IP address, bypassing your VPN. Our check shows whether your addresses are visible through WebRTC. The LiMP VPN app routes traffic so your real address stays hidden.
How LiMP VPN hides your IP address
When you connect to LiMP VPN, all your traffic travels through an encrypted tunnel to a secure server. Websites see the server's IP address instead of yours, and your ISP only sees that an encrypted connection exists, not what's inside it. That keeps your real location, IP address and browsing history private on Android, Windows and in your Chrome browser.
Frequently asked questions about IP addresses and privacy
It's the address the internet sees you under. Your ISP assigns it, and websites use it to estimate your region. A local IP (such as 192.168.x.x) is only visible inside your home network, and all devices behind one router usually share a single public address.
It depends on your ISP. Home connections usually get a dynamic IP that can change after a router restart or once a day. A static IP never changes and usually comes with business plans. Mobile carriers change addresses especially often. Restart your router and press "Check again" to see whether your address changed.
It's an estimate. Geolocation databases map address ranges to where the network is registered — usually your ISP's office or hub, not your home. Accuracy is at the city or region level, and on mobile internet the city may differ from where you are. A website can't find your home address from your IP.
IPv4 addresses look like 203.0.113.45; there are only about 4.3 billion of them and the free pool ran out long ago. IPv6 addresses are 128-bit, like 2001:db8::1, and practically unlimited. Many ISPs hand out both; the tool shows whichever one your device used to reach our site.
An ASN (autonomous system number) identifies a network run by a single organization: an ISP, a cloud provider or a large company. AS15169, for example, is Google's network. Websites and anti-fraud systems use the ASN to tell home users apart from data centers, VPN servers and hosting providers.
It's the set of characteristics your browser reports to every website: system, screen, CPU cores, time zone, languages and more. Unlike your IP, the fingerprint doesn't change when you switch networks or turn on a VPN, and it works even in incognito mode — so it can identify you without cookies.
WebRTC can expose your local and sometimes your public IP address, bypassing your VPN. If this page shows your address in the WebRTC row, websites can read it too. LiMP VPN helps protect you from this leak.
Open the "Look up a domain or IP" tab, enter the domain and press "Check". The tool shows the IPv4 and IPv6 addresses, country, hosting provider and ASN, the reverse DNS record and whether the site responds over HTTPS.
No. Your browser fingerprint is read on your device, and we don't log, store or pass your IP address to third-party services: city and ISP are resolved from a database on our own server. LiMP VPN follows a strict no-logs policy.
Install the LiMP VPN app and turn on protection: your real IP address is replaced with a secure server's address and your traffic is encrypted. Once connected, reload this page — your IP, country and ISP should change.
