Knowledge Center
What is my IP address, and what else is on this page
Your public IP, plus five more network tools, no typing required
1. Automatic IP and location lookup
Your public IP address, approximate city, ISP, and ASN load automatically the moment the page opens.
2. WebRTC leak test
Check whether your VPN is actually hiding your real IP, or leaking it through the browser instead.
3. CIDR calculator and IPv4/IPv6 converter
Scroll down for subnet math, private IP ranges, and conversion between the two address formats.
What this IP tool does
Much more than a plain "what's my IP" page
Public IP, ISP, and ASN lookup
City-level location, network provider, and autonomous system number — all detected automatically, no input needed.
WebRTC leak test
Runs a real ICE candidate check to see if your true IP is exposed by the browser even while a VPN is active.
Browser fingerprint
User agent, screen resolution, timezone, and language — the exact attributes trackers combine to identify your browser.
CIDR / subnet calculator
From /0 to /32 — network address, broadcast, usable hosts, and subnet mask for any prefix.
IPv4 to IPv6 converter
Converts any IPv4 address into its IPv4-mapped IPv6 notation (::ffff:x.x.x.x) for dual-stack systems.
Runs entirely in your browser
CIDR math and fingerprinting happen locally on your device — only the IP/ISP lookup makes an external request.

Common subnet prefixes and how many hosts they hold
When you'll reach for this tool
The scenarios that bring most people here
Confirming a VPN isn't leaking
Run the WebRTC test while your VPN is connected — if your real IP shows up in the results, it's leaking.
Planning a subnet before deployment
Work out how many hosts fit under a given CIDR prefix before configuring a router or cloud VPC.
Troubleshooting a network issue
Check whether an address is private (RFC 1918) or public before you start debugging connectivity.
Identifying who owns an IP
Look up the ASN to find out which hosting provider or ISP a given address actually belongs to.
Checking what a site can see about you
Review your browser fingerprint (user agent, timezone, screen size) to understand your baseline trackability.
Common mistake? Start here
Assuming a VPN hides your IP completely
WebRTC leaks can expose your real IP through the browser even with the VPN tunnel active — always test for it, don't assume.
Confusing a private IP with a public one
Ranges like 192.168.0.0/16 and 10.0.0.0/8 only exist inside a local network — they're never reachable from the public internet.
Expecting street-level location accuracy
IP geolocation gets the country right about 99% of the time, but only nails the city in 60–80% of cases — never the exact address.
Why use this IP address tool
It combines six separate network utilities on one page — IP lookup, WebRTC leak test, browser fingerprint, CIDR calculator, private IP ranges, and an IPv4/IPv6 converter — that would otherwise mean visiting six different sites.
CIDR math and fingerprint detection run locally in your browser; no network data is stored, logged, or sold — only the public IP/ISP lookup makes an external call.

Frequently asked questions
It's the unique number your internet provider assigns to your connection so other computers on the internet know where to send data back to you. This page detects and displays your current public IP automatically, no input required.
