Hi, According '127.0.0.1#47500', '0:0:0:0:0:0:0:1/0#47500':
It's just the different views of the same address (localhost). For example, Ignite started on 10.0.75.1 could be available using next addresses from the same node: >>> Local node addresses: [LAPTOP-I5CE4BEI/0:0:0:0:0:0:0:1, >>> LAPTOP-I5CE4BEI.mshome.net/10.0.75.1, LAPTOP-I5CE4BEI/127.0.0.1, >>> LAPTOP-I5CE4BEI.gridgain.local/172.18.24.193, /172.25.4.187, >>> /192.168.56.1] 0:0:0:0:0:0:0:1/0 is a CIDR notation. You can read more about it here: https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing#CIDR_notation According to VPC Peering and Ignite. I don't think that this scenario was tested. However, you can try to follow common suggestion about how it should be: https://docs.aws.amazon.com/vpc/latest/peering/peering-scenarios.html BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
