Default VPCs
When the first CKS cluster is created via the Cloud Console, a default VPC is created in the same Zone as that cluster, unless a custom VPC is defined.Custom prefixes
Custom VPC Prefixes can be added to custom or default VPCs to allow communication with other VPCs in the same Region, or to remote Cloud providers, or to on-premises networks via a VPN or Direct Connect. Custom prefixes are added to a VPC via the Cloud Console during VPC creation, or during cluster creation at the network configuration step. Two types of prefixes can be configured for VPCs:| Prefix Type | Description |
|---|---|
| Host Prefixes | A range of IP addresses to assign to the Nodes within a VPC, which are used for network communications between Nodes and other resources within the VPC. |
| VPC Prefixes | A range of IP addresses that can be used to communicate with other VPCs in the same Region, or to remote Cloud providers, or to on-premises networks via a VPN or Direct Connect. |

Host Prefixes cannot be modified or removed after they are added to a VPC. Host Prefixes are assigned when the Node boots, so cannot be modified while running.
Default VPC names
CoreWeave automatically creates a default VPC when a cluster is first created. The name of a new default VPC uses the following format:cw-vpc-<CLUSTER-NAME>-<SIX-DIGIT-STRING>
The name of the default VPC may be seen by clicking the Customize option beside the default VPC selector during cluster creation.
