A subnet is a network that manages ECS network planes. It supports IP address management and DNS. The IP addresses of all ECSs in a subnet belong to the subnet.

By default, ECSs in all subnets of the same VPC can communicate with one another, while ECSs in different VPCs cannot communicate with one another.

You can create VPC peering connections to enable ECSs in different VPCs to communicate with one another. For details, see VPC Peering Connection.
