Description

This is an optional change, to help diagnose relay address resolution
issues.

Relays (and bridges) should log the address chosen using each address
resolution method, when:

  • address resolution succeeds,
  • address resolution fails,
  • reachability checks fail, or
  • publishing the descriptor fails.

These logs should be rate-limited separately for successes and failures.

The logs should tell operators to set the Address torrc option for IPv4 and
IPv6 (if available).
