WHY IP BROWSER TOOLS

Built differently.

Privacy first

All detection runs client-side. No server logs, no analytics, no cookies dropped on tool pages.

Always accurate

We use native browser APIs and real-time IP intelligence — not cached or approximated data.

WebRTC leak detection

Our IP tool exposes WebRTC IP leaks that VPN users miss, something most tools skip entirely.

DNS leak test

Verify your DNS requests aren't bypassing your VPN tunnel and exposing your real ISP.

Fingerprint score

See a trackability score showing how unique your browser is compared to the general population.

Export your data

Copy any result as JSON with one click. Useful for debugging, network audits, and research.

Understanding Your IP Address

Every device connected to the internet is assigned a unique identifier known as an IP address — short for Internet Protocol address. When you browse the web, stream a video, or send an email, your IP address travels with every data packet, acting as a return address that allows servers to send information back to you. Understanding your IP address is the first step to understanding your digital footprint online.

IPv4 vs. IPv6: Two Formats, One Identity

Most internet connections today use IPv4 addresses — 32-bit numbers written as four groups of digits separated by dots, such as 203.0.113.1. Because the world's pool of IPv4 addresses is nearly exhausted, Internet Service Providers are progressively adopting IPv6, a 128-bit format that looks like 2001:db8::1. Your device may have one or both types depending on your ISP and router configuration.

Public IP vs. Private IP

Your router assigns private IP addresses — typically in the 192.168.x.x or 10.x.x.x range — to every device on your home or office network. These private IPs are invisible to the public internet. The IP address this tool detects is your public IP — the single address your ISP assigns to your router, visible to every website, service, and server you connect to.

What Does Your IP Address Reveal?

Your public IP address exposes more than most people realise:

  • Approximate location — city, region, and country (not your exact street address)
  • Your ISP — the company providing your internet connection
  • AS number — your ISP's autonomous system number used for network routing
  • Connection type — whether you're on residential, business, or datacenter infrastructure
  • Hostname — the reverse DNS hostname of your IP, if one is configured

Dynamic vs. Static IP Addresses

Most residential connections use dynamic IP addresses that change periodically — your ISP assigns a new address from a pool whenever your lease expires or when you restart your router, typically every 24–72 hours. Businesses often pay for static IP addresses that remain constant, which is important for hosting servers, configuring remote access, or maintaining firewall allowlists.

VPNs, Proxies, and IP Masking

Virtual Private Networks (VPNs) and proxy servers replace your real IP address with one belonging to the VPN provider's servers. This protects privacy, bypasses geographic restrictions, and secures connections on public Wi-Fi. If you're using a VPN, the IP shown by this tool will be your VPN server's IP — not your real home address. However, browsers can inadvertently reveal your real IP through WebRTC, a technology used for peer-to-peer video and audio. Our IP Address tool includes a WebRTC leak test so you can verify your VPN is truly masking your identity.

Beyond Your IP: Browser Tools for Complete Visibility

IP Browser Tools goes further than just your IP address. Our complete suite of browser tools reveals your browser version and rendering engine, your user agent string, screen resolution and pixel ratio, device hardware capabilities, and your full device fingerprint. The DNS leak test checks whether your DNS queries are bypassing your VPN, and the speed test measures your real download and upload throughput. All detection happens instantly in your browser — nothing is stored on our servers, and no sign-up is ever required.

Frequently Asked Questions

How do I check my IP address?
The easiest way is to open ipbrowsertools.com/my-ip-address. The tool automatically detects and displays your public IPv4 and IPv6 address the moment the page loads — no sign-up or installation required. Your public IP is assigned by your Internet Service Provider and is visible to every website you visit. The tool also shows your ISP name, approximate location, and whether your real IP is being leaked via WebRTC even when a VPN is active.
How to access VPN IP Address?
When connected to a VPN, your real IP is replaced by the VPN server's IP. Visit my-ip-address while your VPN is active — the IP displayed will be the VPN server's IP. However, some browsers expose your real IP through WebRTC even with a VPN active. Our tool's built-in WebRTC leak test will flag this. If your real IP appears in the WebRTC section, enable WebRTC leak protection in your VPN client or browser settings.
What is my location?
Your approximate location is determined from your IP address — every IP is registered to a geographic region, allowing estimation of your city, region, country, and coordinates. Visit ipbrowsertools.com/my-location to see your IP-based location. For higher accuracy, the tool can request your browser's GPS geolocation (with your permission), which can pinpoint your position to within a few metres on a compatible device. Note: IP-based location may be off by tens of kilometres when using a VPN, mobile data, or a proxy.
What is a DNS leak and how do I test for it?
A DNS leak occurs when your secure tunnel (like a VPN) fails to route your DNS requests, causing them to go directly to your ISP's DNS servers instead of the VPN's secure DNS servers. This leaks your real location and browsing history to your ISP. Our DNS Leak Test sends multiple random requests to check if any queries fall outside your VPN's server list, warning you of leaks.
How do I check my website's HTTP security headers?
You can check your security configuration using our HTTP Header Lookup. Enter your domain, and our system fetches the response headers from our edge node. It calculates a security score out of 100 and issues a grade (from A+ to F) based on the presence of critical protective headers like CSP (Content Security Policy), HSTS, X-Frame-Options, and Referrer-Policy.
Why does my IP location differ from my actual physical location?
IP-based geolocation is an estimate. Databases map IP subnets to geographic coordinates registered by your ISP. If your ISP hosts routing hubs in a neighboring city, your location will reflect that hub. Additionally, using a VPN, proxy, or mobile data will route your traffic through remote servers, changing your apparent location.
