Overview
Description

Constellix is a managed DNS platform, now operating as a DigiCert company, built around enterprise-grade multi-CDN management, traffic routing and DNS availability. It aims to prevent outages and optimize content delivery performance by intelligently routing traffic and monitoring uptime across a business's infrastructure. The platform includes companion tools such as Sonar for uptime monitoring and an analytics dashboard for visibility into DNS and routing performance, and is positioned for enterprise customers that need high-availability DNS alongside multi-CDN failover. Since joining DigiCert, Constellix retains its own brand while being integrated into DigiCert's broader DNS and security product lineup.

Technitium DNS Server is a free and open-source DNS server that anyone can self-host to take control of their own DNS resolution, whether for a home network or an organization. It combines recursive and authoritative DNS with support for encrypted protocols like DNS-over-HTTPS, DNS-over-TLS, and DNS-over-QUIC. It also includes network-wide ad and malware blocking through configurable blocklists, a built-in DHCP server, DNSSEC support, and a web console with API access, making it a full DNS and DHCP toolkit rather than a simple resolver.
