##### additional mixnode config options #####

# Optional address announced to the directory server for the clients to connect to.
# It is useful, say, in NAT scenarios or wanting to more easily update actual IP address
# later on by using name resolvable with a DNS query, such as `nymtech.net:8080`.
# Additionally a custom port can be provided, so both `nymtech.net:8080` and `nymtech.net`
# are valid announce addresses, while the later will default to whatever port is used for
# `listening_address`.
