Usage Limitations
- The IP ranges of a VPC and subnet cannot be modified after creation.
- The cloud platform reserves the first two IP addresses and the last IP address of each subnet for IP networking. For example, if the subnet CIDR is
172.16.0.0/24, the IP addresses reserved by the cloud platform are:172.16.0.0,172.16.0.1and172.16.0.255. - When CVMs are added to a VPC, the system will randomly assign a private network IP address to this instance in the specified subnet by default, and users can reassign the private network IP address of each CVM after the creation of CVMs.
