DNS leak test shows more than 1 DNS server. Does this mean some requests are bypassing the PiHole?
My setup is:
192.168.1.1. Gateway router (with locked DNS settings due to trash ISP. I can't flash it).
I have disabled DHCP on the this router.
DNS-Over-HTTPS but using Quad9 upstream address.
Have set the PiHole settings for DOH like this (deselecting the originally set "Quad9 (filtered, DNSSEC)" for IPv4 and inputting the custom value.
I can see the PiHole graphs start to populate and have noticed ads being blocked so it is working.
However I was looking for ways to test this implementation and following this reddit post ran a DNS leak test.
My results show multiple DNS servers. Results
The WoodyNet results I understand to be Quad9 servers but there you can see 4 other servers, which are my ISP DNS servers.
Does this mean that some of my requests are being sent to Quad9 and other times to my ISP DNS?
Or is it normal that all these servers appear but actually my PiHole is always making sure that only the Quad9 servers are the ones doing the lookups?
Thank you for your help.
First timer dabbling in world of PiHole and never gone so deep into my home network before.
Gateway router is Technicolor AGHP (never heard of it before)
