LibreDNS has a new endpoint
This new endpoint is unique cause it blocks by default Ads & Trackers !
We are currently using Steven Black’s hosts file.
noticeable & mentionable
LibreDNS DOES NOT keep any logs and we are using OpenNIC as TLD Tier1 root NS
Here are my settings
LibreOps & LibreDNS
LibreOps announced a new public service: LibreDNS, a new DoH/DoT (DNS over Https/DNS over TLS) free public service for people that want to bypass DNS restrictions and/or want to use TLS in their DNS queries. Firefox has already collaborated with Cloudflare for this case but I believe we can do better than using a centralized public service of a profit-company.
So here are my personal notes for using LibreDNS in firefox
TRR mode 2
Now the tricky part.
TRR mode is 2 when you enable DoH. What does this mean?
2 is when firefox is trying to use DoH but if it fails (or timeout) then firefox will go back to ask your operating system’s DNS.
DoH is a URL, so the first time firefox needs to resolve
doh.libredns.gr and it will ask your operating system for that.
There is way to exclude doh.libredns.gr from DoH , and use your
/etc/hosts file instead your local DNS and enable TRR mode to 3, which means you will ONLY use DoH service for DNS queries.
# grep doh.libredns.gr /etc/hosts 188.8.131.52 doh.libredns.gr
TRR mode 3
Try DNS Leak Test to verify that your local ISP is NOT your firefox DNS
Thunderbird also supports DoH and here are my settings
PS: Do not forget, this is NOT a global change, just your firefox will ask libredns for any dns query.
