PowerDNS is an open-source DNS software created in 1999 in the Netherlands. It provides both authoritative and recursive servers and supports features such as DNSSEC, load balancing, and database backends for zone storage. It is maintained by PowerDNS.com BV, a company later acquired by Open-Xchange.
PowerDNS is a DNS software stack designed to run reliable DNS infrastructure in production. It is commonly used to serve authoritative DNS zones for domains and to operate a high-performance recursive resolver for fast lookups.
It supports DNSSEC so zones can be signed and validated, which helps protect users against certain types of DNS manipulation. It also offers flexible ways to store and manage zone data, which makes it suitable for both simple deployments and large platforms that need database-backed operations.
PowerDNS fits well into automated environments because it can be managed programmatically and integrated into provisioning workflows. It is often deployed with DNSdist, which adds a DNS-aware traffic layer that can distribute queries across multiple backends, improve resilience, and apply filtering and routing rules to handle abusive traffic more effectively.
For authoritative DNS, BIND 9 is the most widely deployed traditional choice and is still very common across hosting providers, enterprises, and universities. Microsoft DNS is also heavily used in corporate environments because it is tightly integrated with Active Directory.
For operators who want high performance and a simpler authoritative-only design, NSD and Knot DNS are widely used, especially among large DNS operators and some registries and TLD setups. They are often selected when the goal is serving zones efficiently without extra features.
