I have a windows server 2012 r2 instance on EC2 under VPC, I have two Network Interfaces. The Primary Private IP is shown in windows for both. I have a secondary IP address on one of the network interfaces, This secondary IP does not seem to be bound to the interface. The Interface with 10.0.0.186 should also have 10.0.0.254
Am I missing something?
