PowerDNS dnsdist

PowerDNS DNSdist is a state-of-the-art DNS load balancer and security solution that enhances performance, privacy, and protection for DNS deployments.

Description

PowerDNS DNSdist is a high-performance DNS proxy and load balancer designed to optimize DNS traffic and enhance security. It acts as a front-end for recursive or authoritative DNS servers, improving performance by intelligently routing queries and distributing the load. DNSdist seamlessly integrates with PowerDNS Recursor but also supports legacy DNS servers, offering a versatile solution for various environments. It provides crucial security features such as protection against DDoS attacks, DNS tunneling, and exfiltration. Furthermore, it supports all standardized DNS encryption mechanisms (DoT, DoH, DoQ, and DoH3), safeguarding user privacy and preventing DNS requests from being diverted to third-party providers. DNSdist's flexible policy engine, based on Lua scripting, allows for customization to meet specific needs and local requirements.
