The history of PowerDNS

The company started in 1999 with the task to write load balancing software for V3 Redirection Services for “come.to”, “browse.to“, and “go.to”. Back then, it was still a close-source. After the Dot Com Bubble, the company needed to re-think their future and released the software as an open-source. It started to provide commercial services from 2005 and in 2015 became a part of Open-Xchange.

PowerDNS platform

PowerDNS or pdns is an open-source (GPL) software. It provides software to create authoritative DNS, Recursive DNS, DNS loading balancer, Debugging tools, and APIs to provision zones and records. A complete suite of DNS-related software that you can use for your company.

Authoritative Server supports DNSSEC. It hosts 30% of all domain names in Europe and close to 90% of all DNSSEC domain in the same area.

Recursor (recursive DNS)

It provides a high-performance recursive DNS server. PowerDNS Recursor can use multiple processors. Just like the Authoritative Server, it supports various scripts. A good advantage is that it can be reconfigured without downtime.

Dnsdist is a powerful load balancer. It can route the traffic to the optimal servers delivering excellent performance. It also can block abusive traffic and provide DoS protection.
