Kuburitswa kweiyo caching DNS server PowerDNS Recursor 4.7 iripo, iyo ine basa rekudzokorora zita rekugadzirisa. PowerDNS Recursor yakavakirwa pane imwecheteyo kodhi base sePowerDNS Authoritative Server, asi PowerDNS inodzokororwa uye ine chiremera DNS maseva anogadzirwa kuburikidza neakasiyana ekusimudzira uye anoburitswa sezvigadzirwa zvakasiyana. Iyo kodhi yeprojekiti yakagoverwa pasi peGPLv2 rezinesi.
Sevha inopa maturusi ekuunganidzira kure kwenhamba, inotsigira kutangazve ipapo, ine yakavakirwa-mukati injini yekubatanidza vanobata mumutauro weLua, inotsigira zvizere DNSSEC, DNS64, RPZ (Response Policy Zones), uye inokutendera kuti ubatanidze blacklists. Zvinogoneka kurekodha mhinduro senge BIND zone mafaera. Kuve nechokwadi chekuita kwepamusoro, nzira dzemazuva ano dzekubatanidza nzira dzinoshandiswa muFreeBSD, Linux uye Solaris (kqueue, epoll, /dev/poll), pamwe nepamusoro-inoita DNS packet parser inokwanisa kugadzirisa makumi ezviuru zvezvikumbiro zvakafanana.
Mushanduro itsva:
- Zvinokwanisika kuwedzera mamwe marekodhi kumhinduro dzakatumirwa kumutengi kuti ape ruzivo rwakakosha pasina chikonzero chekutumira chikumbiro chakasiyana (semuenzaniso, mhinduro kune MX rekodhi chikumbiro inogona kugadzirwa kuti ibatanidze zvine hukama A uye AAAA marekodhi).
- Zvinodiwa zveRFC 9156 zvakatariswa mukushandiswa kwerutsigiro rwekubvunza zita rekuita minimization mechanism ("QNAME minimisation"), izvo zvinobvumira kuwedzera kuvanzika nekumira kutumira zita rekutanga reQNAME kuseva iri kumusoro.
- Kugadziriswa kweIPv6 kero dzeDNS maseva asina kunyorwa muGR (Glue Record) marekodhi kuburikidza iyo registrar inotumira ruzivo nezve DNS maseva anoshandira iyo domain inopihwa.
- Kuitwa kwekuedza kweimwe-nzira yekusimbisa yeDNS server tsigiro yeDoT protocol (DNS pamusoro peTLS) inokurudzirwa.
- Yakawedzera kugona kudonha kumashure kumubereki NS rekodhi yakaiswa kana maseva ari mumwana NS rekodhi seti isingaite.
- Yakawedzerwa rutsigiro rwekutarisa chokwadi cheZONEMD RR marekodhi (RFC 8976) akawanikwa kubva kucache.
- Yakawedzera kugona kwekubatanidza vanobata mumutauro weLua, inodanwa padanho rekupedzisa kugadzirisa (semuenzaniso, mune vakadaro vanobata unogona kushandura mhinduro yakadzoserwa kumutengi).
