After restart with the new address the server will notice it and log a warning, but it will keep token ownership as long as it keeps the old host id (meaning it must use the same data directory as before restart). At the same time, *do not* use the replace_address option: it assumes empty data directory and will try to stream data from other replicas into the node. -- Alex
