What's My IP Address?
Your public IP and network information โ instantly, no tracking.
Free IP & Network Tools, Run Privately in Your Browser
IPChecks is a free suite of network diagnostic tools for anyone who wants to understand their internet connection. In seconds you can see your public IP address and location, resolve the DNS records of any domain, look up who registered a website, investigate any IP address, inspect the HTTP headers your browser sends, test whether WebRTC is leaking your real IP, and check if your address sits on a spam blacklist. Every tool is free, requires no account, and needs no installation โ just open a page and click.
The tools are built for web developers, system administrators, network engineers, students and everyday privacy-conscious users alike. If you are troubleshooting a slow site, diagnosing email that keeps landing in spam, verifying a domain before you buy it, or simply curious about how the internet sees your device, this is the place to start.
Your privacy matters. All of our tools run directly in your browser, and the data they produce โ your IP address, the domains or addresses you enter โ is processed on your device and is never stored or logged by us. Where a tool needs live data, it queries a public API only to fetch the answer for that single request; nothing is saved on our servers.
