What Is My IP
Your IP, provider and country, browser headers, proxy signs and a WebRTC leak check.
Below is everything any site you visit can learn about you: your address and ISP, browser headers, time zone and screen, plus a check for a leak of your real address past the tunnel. To look up someone else's address or a domain, open the whois service.
Your IP address
IPv4 · a public internet address
What is visible about you
- No proxy headers — the connection looks direct
This is not a guarantee of anonymity: a system-level tunnel does not add such headers. There is a WebRTC leak check below.
- You are presenting yourself as an automated crawler
That is how sites will treat you — with all the restrictions applied to robots.
What your browser tells every site
| Header | Value | What it means |
|---|---|---|
User-Agent | Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; ClaudeBot/1.0; +claudebot@anthropic.com) | How your browser introduces itself to sites. |
Accept | */* | Content types your browser is willing to accept. |
Accept-Encoding | gzip, br, zstd, deflate | Supported compression methods. |
Real address leak via WebRTC ?
The page shows the address you arrived from right away, along with everything any site can tell about you from that address. There is nothing to click.
Next to the address you see its version, reverse DNS record, provider, network range, and country. The details come straight from the registries, with no third-party lookup services in between.
What is visible besides the address
Your browser sends every site a set of headers: how it identifies itself, which languages you prefer, which page you came from. The headers are listed with an explanation of what each one means.
The User-Agent string gets a separate breakdown: browser and its version, operating system, and device type.
Signs of a proxy
When a request goes through a proxy, the proxy often announces it with headers such as X-Forwarded-For or Via. The tool shows them as they are: the original address often sits right in the value.
Leaking your real address
WebRTC, the browser calling technology, can reveal your address past any proxy. The check tells you whether your real address shows through it.
The same section compares your browser time zone with the country of your address: a mismatch gives away a proxy. Your screen and graphics card are listed too, since sites use them to profile your device.
