Re: [tor-relays] lets stop using central big DNS resolvers (Google, Level3, OpenDNS, Quad9, Cloudflare)

Assuming you can install whatever software you like, I recommend running your own instance of Unbound on your exit node machines. Current Unbound versions support DNSSEC validation, QNAME minimisation, etc. While using your ISP's resolvers works as a fallback, a local resolver is better and easy enough to set up.

We are currently using Unbound plus 2 ISP name servers in /etc/resolv.conf. I still occasionally see the dreaded "all nameservers have failed" message, even though the latest Tor release has fixes for DNS performance (IIRC).

Kind regards, Alexander
