Virtual Private Clouds (VPCs) are the basis for using Tencent Cloud services. When purchasing an instance such as CVM, CLB or TencentDB in a region that does not have existing VPCs, a default VPC and subnet will be automatically created.
The default VPC and subnet are created together with your instance, and do not count against your quota in the region. They work the same as the manually-created ones. There can only be one default VPC and subnet in each region. You can delete the default VPC and subnet if you no longer need them.
You can refer to this document to create a VPC instance on the console if the default or existing ones are not suitable.
The CIDR blocks of the VPC and subnet cannot be modified after creation.
10.255.255.255(mask range between 16 and 28)
172.31.255.255(mask range between 16 and 28)
192.168.255.255(mask range between 16 and 28)
10.0.0.0/16, then its subnet IP range can be
After the VPC and subnet have been created, you can deploy resources including CVM and CLB within the VPC.
