Plain-English guides on IP addresses, networking, VPNs, and online privacy
Every time you connect to a website, your device shares more information than most people realise — your IP address, approximate location, ISP, browser fingerprint, HTTP headers, and more. This blog covers what that information reveals, who can see it, and what you can do about it.
