# Add/Edit Subnet

The Service Portal Cloudeka provides multiple subnet function that can be used to divide VPC network into several distinct subnets without having to change existing subnets. Here are the steps to add to the subnet configuration used in VPC configuration:

* On the **Network** page under the **VPC** tab, select the VPC where you want to add a subnet by clicking the VPC name in the **Name** column.
