A fast, private, no-nonsense set of network tools.
whatsip.nl shows you your public IP address and a handful of related network diagnostics — your browser details, request headers, IPv6 support, WebRTC exposure, browser storage, and approximate location. Each tool does one thing clearly, with a short explanation of what the result means.
We do not set tracking cookies, we do not run analytics, and we never store your IP address. Information about your connection is read at the edge only to display it back to you. Anything read from your browser (device, storage, location) stays in your browser unless you explicitly act on it.
The site is plain HTML served from Cloudflare's global edge, so pages load in well under a tenth of a second almost anywhere. There is no heavy framework and no bloat — a first visit is only a few kilobytes, and later pages are mostly cached.
Some things genuinely cannot be measured accurately in a browser — a true line-speed test or a real DNS-leak test, for example. Rather than show misleading numbers, we either leave those out or point you to a dedicated tool that does the job properly.
