> This is a new protocol, typically added somewhere above {{NAKACK2}}. When {{TP.use_ip_addr}} is true, {{IpAddressUUID}} addresses will be used.
> If {{Discovery.max_rank_to_reply}} is less than the max rank of the cluster view, not all members will receive discovery responses. They therefore won't have a mapping between the address and the logical name for all members.
> {{NAMING}} fixes this by having the joiner multicast the address:name mapping after joining, and by everyone sending their mapping to the newly joined member as well.
> Note that this protocol is not strictly necessary; as {{IpAddressUUID}} addresses will also work without logical names mapped to them, but it improves legibility, e.g. of logs.
