PowerDNS Basics

PowerDNS has been designed to serve both the needs of small installations as well as very large query volumes on large numbers of domains. Through use of clever programming techniques, PowerDNS offers very high domain resolution performance.

PowerDNS was also designed with security in mind. By the use of language features, the PowerDNS source code is reasonably small which makes auditing easy. In the same way, library features have been used to mitigate the risks of buffer overflows.

PowerDNS is able to give a lot of statistics on its operation which is both helpful in determining the scalability of an installation as well as for spotting problems.
