Yes. A VPC is a regional (such as Guangzhou, Beijing, or Seoul) resource, and the subnets in the VPC are resources in availability zones (such as Guangzhou Zone 1 or Guangzhou Zone 2). Therefore, subnets in one VPC can be deployed in different availability zones in the same region. A CVM is also availability zone specific as the subnet it belongs to. So, if you purchase CVMs under subnets in availability zones, you can deploy them in different availability zones.
A VPC supports a maximum of 65,533 private IP addresses for Tencent Cloud service instances.
Classless Inter-Domain Routing (CIDR) is a specified independent network address block that uses with IP and mask to implement the overall division of network. It eliminates the concepts of traditional class A, B and C addresses as well as subnet partitioning, and assigns the IP address spaces more efficiently. You need to create subnets in CIDR format when creating a VPC and its subnets. For example, to create an IP range of
10.0.16.0 - 10.0.17.255:
This IP range changes to
00001010.00000000.00010000.00000000 - 00001010.00000000.00010001.11111111 in binary format that has the same first 23 digits, and to
10.0.16.0/23 in CIDR format.
