Supporting wildcard rules. - Medium: Adds Anti-DPI to defeat deep packet inspection. - Max: Adds full on-device intrusion detection (HIDS) with JA4 fingerprinting. - Prefer full control? Custom settings remain fully accessible for advanced users. Host Intrusion Detection System (HIDS) ADFastDNS analyzes network traffic in real time without decrypting private content: - Beacon Guard: Identifies malware and spyware by detecting persistent connection patterns that evade standard consumer tools. - TLS & Hello Packet Anomaly Detection: Uses professional-grade JA4 fingerprinting to score encrypted connections and block malicious payloads before data transmits. - IP & Geo Firewall: Blacklist specific IPs or set blocking rules per country. - Advanced Exploitation Defense: Native protection against DNS Tunneling, DNS Rebinding, SNI Spoofing, and DNS Data Exfiltration. Advanced Anti-DPI Engine - Packet Fragmentation: Intelligently splits TLS and QUIC Crypto ClientHello packets. - Adaptive Connection Tuning: Automatically learns whether packet splitting helps or hurts reliability per connection (for TCP/TLS and QUIC connections), adapting locally without external servers. - Traffic Shaping: Mimics natural timing patterns to make proxy traffic statistically harder to detect and throttle. Core Features - Next-Gen Protocols: Supports DNS over HTTPS (DoH) & DNS over QUIC (DoQ / HTTP/3). - Custom DNSoH Endpoints: Compatible with Cloudflare, Google, AdGuard, NextDNS, or any custom URL. - System-Wide Blocking: Stop ads and trackers using your favorite filter lists. You can temporarily disable the ADBlocking using the toggle in the widget (no need to open the app) - Performance Optimization: On-device DNS cache for instant responses, per-domain proxy routing, and automatic Wi-Fi whitelisting. - Network Tools: Local DNS resolver (hosts file), QUIC Connection Migration (RFC 9000), and real-time threat statistics. - Privacy & Ecosystem: Configure 2 DNSoH endpoints working together for maximum privacy. Zero data collection, and the ability to extend filtering to other network devices via SOCKS5 proxy. Why ADFastDNS?
