PowerDNS Recursor ('''pdns_recursor'''<ref>{{cite web|url=https://doc.powerdns.com/recursor/ |title=PowerDNS Recursor |publisher=Doc.powerdns.com |date= |accessdate=2014-05-11}}</ref>) is a ''resolving'' DNS server, that runs as a separate process.

This part of PowerDNS uses a combination of native threads and user-space threads, through the use of  [[Boost (C++ libraries)|Boost]] and the MTasker library,<ref>[http://ds9a.nl/mtasker/ MTasker<!-- Bot generated title -->]</ref> which is a simple cooperative multitasking library. It is also available as a standalone package.

It does not have to run a pdns_server process as a gatekeeper for pdns_recursor, if the goal is simply to provide caching/recursing/resolving nameservice as running pdns_recursor on its own is even more efficient than behind the authoritative component.

Support for [[DNSSEC]] validation was added to the '''pdns_recursor''' in version 4.0.
