The weirdest header on the web, decoded. Every token in a modern User-Agent — which ones lie, which ones are frozen, how Client Hints are replacing the whole mess, and whether spoofing your UA actually helps. Plus a bot-detection cheat sheet.
Geolocation accuracy, ASN lookups, reverse DNS, IPv6 prefix leaks, CGNAT, and the myths that won't die. A grounded breakdown of what a site does and doesn't learn from your IP — and what a VPN really changes.
Every HTTP request you make carries 20–30 headers. This post walks through 15 of them — User-Agent, sec-ch-ua, Accept-Language, Referer, Cookie, DNT/Sec-GPC, X-Forwarded-For and more — ranked by how much each one reveals, with a per-header mitigation.
Canvas, WebGL, AudioContext, installed fonts, hardware concurrency, locale — six fingerprinting signals with entropy badges, real examples, and what each one actually gives away. Plus what defences work in 2026 and what's theatre.
WebRTC leaks expose your real IP even with a VPN running. What the leak actually is, why browser-extension VPNs almost always leak, and step-by-step fixes for Chrome, Firefox, Edge, Safari, and Brave — plus the VPN-level fix that survives browser updates.
