local DNS Resolver?

[tbaschak]

Installing an optional local DNS resolver on the Tor server itself may be something to explore.

There was some discussion on this on the tor-relays list, thread begins here.

This will reduce the number DNS queries leaving the node, one operator quoted the following:

queries forwarded 143488, queries answered locally 29384

This has reduced outbound DNS queries by 5%. Thats 5% less correlatable information in the above case.

This would depend on how much memory is available on the Tor server.

Suggested resolvers: unbound, powerdns recursor, or powerdns dnsdist
