Technitium
This an open-source software suite centered around networking tools that prioritize privacy, security, and self-hosting capabilities. Primarily known for its DNS Server, the platform has solutions like a peer-to-peer messenger, MAC address changer, and DNS client, all designed for users looking for control over their environments. Available under the GNU GPLv3 license with source code hosted on GitHub, Technitium enables customization and community-driven development across Windows, Linux, macOS, and Raspberry Pi devices
The DNS Server functions as both an authoritative and recursive resolver, deployable with minimal setup via installers, Docker images, or portable binaries. Users access a web console at localhost:5380 for configuration, supporting features like automated block list updates for ads and malware, caching with prefetching, and integration with encrypted protocols such as DNS-over-TLS, DNS-over-HTTPS, and DNS-over-QUIC. Complementary tools include Technitium Mesh for end-to-end encrypted P2P messaging using cryptography like DHE-2048 and AES-256, and MAC Address Changer for network adapter spoofing and presets on Windows systems. The entire ecosystem remains fully open source, giving transparency and allowing modifications for specific needs.
Everyday Use
Organizations want to reclaim control from ISP-monitored DNS queries, which often expose browsing habits despite HTTPS encryption. When self-hosting, users block ads network-wide at the DNS level, accelerate site loading through persistent caching that survives restarts, and route traffic securely via public resolvers like Cloudflare or Quad9 over encrypted channels. Performance shines in load tests exceeding 100,000 requests per second on standard hardware, a built-in DHCP, multi-user access with 2FA, and HTTP APIs enable integration into different environments from home labs to enterprise setups. This combination gives privacy gains, performance boosts, and granular logging without relying on third-party clouds vulnerable to outages or data harvesting.
Advantages Over Pi-hole and AdGuard Home
Pi-hole excels in lightweight, ad sinkholing on Linux but lacks native authoritative zone hosting, DNSSEC signing, or clustering for redundancy across multiple servers. AdGuard Home offers user-friendly encrypted DNS and parental controls, yet it prioritizes simplicity over enterprise-scale features like catalog zones, dynamic updates with TSIG, or regex-based blocking tailored per client subnet. Technitium bridges this gap for network experts, supporting split-horizon DNS, geolocation responses via custom apps, zone transfers over QUIC/TLS, and IPv6-native operations, all manageable from one console.
Proprietary APP records allow custom logic for requests, for split-horizon setups where internal users see private IPs and external queries resolve publicly, ideal for hybrid workforces. DNSSEC validation with NSEC3 and algorithms like EdDSA secures zones against spoofing, complemented by DANE TLSA for certificate pinning and rebinding protection. For compliance-heavy operations, query logging, extended DNS errors, and EDNS Client Subnet support provide audit trails and geolocation-aware responses without external dependencies. Compared to Pi-hole's Debian-centric simplicity or AdGuard's family-oriented dashboard, Technitium's clustering unifies management of failover instances, while built-in forwarders with latency-based selection ensure reliability even under high loads.
Privacy and Security
It help fortify networks by encrypting upstream queries, validating signatures, and minimizing QNAME leaks per RFC 9156. Features like CNAME cloaking thwart ad redirects, while ANAME records enable apex CNAME flattening for web apps. For businesses eyeing sovereignty, self-hosting eliminates vendor lock-in plaguing cloud DNS, with GitHub's active development ensuring updates like QUIC zone transfers keep pace with protocols. Pi-hole and AdGuard suffice for residential ad-blocking, but Technitium helps SMEs with authoritative control, reducing reliance on external resolvers and enhancing resilience against ISP hijacks or DDoS via proxy routing
