# port 53 and the source IP of that connection is used to pick the interface.
# This happens even if `protocol` is set to `udp` when no interface is specified.
#
# All valid IP addresses of the selected interface (whether autodetected or not)
# will be used. An IP is considered valid if it is not multicast (v4/v6), not
# loopback (v4/v6), not link local (v4/v6), and not broadcast (v4).

# secret*.

# If the standard RUST_LOG environment variable is set, it supercedes this config
# option.
