On the Network tab, you can configure cluster and container CIDR blocks.

Cluster Network

**Table 1** Parameters
Parameter	Description
VPC	VPC where the cluster resides. A VPC provides an isolated virtual network for cloud servers, cloud containers, and cloud databases. You can configure and manage the network as required. You can configure a CIDR block for the VPC, create subnets, configure security groups, and even assign EIPs and allocate bandwidth in your network, enabling secure and easy access to your service system.
VPC CIDR Block	IP address range of the VPC for the cluster.
Network Model	Only cloud native network 2.0 is supported.

Service Settings

Service CIDR Block: IP address range of the ClusterIP service for the cluster. The Service CIDR block cannot overlap with the container subnet CIDR block and can be used only in the cluster.

Container Network

If you need to set a different container subnet or security group for a namespace or workload, you can create a custom container network configuration and associate the namespace or workload. For details, see Associating a Subnet and Security Group with a Namespace or Workload Using a Container Network Configuration.

Associating containers with a subnet: Container IP addresses are allocated from this subnet. Only the containers in the same namespace or for running the same workload can communicate with each other.
Associating containers with a security group: You can configure security group rules for containers in the same namespace or for running the same workload to allow or deny traffic to and from the containers.
