hi, i just install pihole ( on a raspberry pi0w for testing, my syno did not have docker ) , and i saw that my nas ( synology ds414 ) make many many dns query(s) , like 1700 by minutes
Feb 7 06:33:30 dnsmasq[10028]: query[ANY] . from 192.168.0.254
Feb 7 06:33:30 dnsmasq[10028]: forwarded . to 208.67.222.222
Feb 7 06:33:30 dnsmasq[10028]: forwarded . to 208.67.220.220
Feb 7 06:33:30 dnsmasq[10028]: query[ANY] . from 192.168.0.254
(192.168.0.254 is my synology )
208.67.22x.xxx is open DNS ( it's that i have configured in pihole )
about 20 request by minutes .... but why ?
this phenomen appears when i set my pihole on synoloygy/parameters/network/prefered dns server .
and it stop when i select another dns ( like my isp )
but how i can know witch program use this amount of dns querry ?
