Ignite will try to connect to each address specified in the addresses section and establish a connection. In the case of a multicast ip finder, it will use a multicast group to scan for nodes.
In general one node needs to discover another and establish a socket connection on a specified address/port in order for communication to work. In your situation where one node has an addresses field and the other one doesn't, the connection could still be established provided that the multicast finder can locate the server based on a multicast group. It is best to put all relevant ips into the addresses section or create a shared multicast group. more information here: https://apacheignite.readme.io/docs/tcpip-discovery -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
