If you need a public DNS resolver you can use Njal.la DNS.
For IPv4:
95.215.19.53
For IPv6:
2001:67c:2354:2::53
You can use DNS-over-HTTPS with Mozilla Firefox and Thunderbird too.
In Firefox open the about:config
page and change network.trr.mode
to 2
to use DNS Over HTTPS but keep regular DNS as a fallback. Change network.trr.uri
to https://dns.njal.la/dns-query
too.
In Thunderbird open Preferences
, General
tab, scroll down and press the Config Editor
button. Change network.trr.mode
to 2
(same reason as Firefox above) and update network.trr.custom_uri
, network.trr.default_provider_uri
and network.trr.uri
to https://dns.njal.la/dns-query
too.
