Deep technical defense against proxy leaks and risk linking: master WebRTC ICE/STUN UDP bypasses, recursive DNS leak containment, and Canvas/WebGL/Client-Hints consistency.
Understand silent JS RTCPeerConnection ICE gathering, srflx UDP bypasses over TCP proxies, and per-browser mitigation trade-offs.
How silent JavaScript exposes real IPs via UDP STUN srflx candidates despite TCP proxies, domestic vs. global STUN checks, mDNS LAN masking, and fixes.
Trace how split-routing rules, socks5 local resolution, DoH overrides, and IPv6 leak DNS, plus Fake-IP & socks5h fixes.
See how authoritative servers log your recursive ISP resolver, the 4 root causes of proxy DNS leaks, random subdomain audits, and Fake-IP / socks5h fixes.
Break down Canvas 2D, WebGL GPU, AudioContext, font widths, and Client Hints—and why IP-to-browser consistency beats uniqueness.
Explore base specs, Canvas 2D, WebGL, AudioContext, font metrics & Client Hints—plus why internal consistency beats randomness for risk scoring.
