VPC

Basic Concepts

  • VPC: A private network space in a region. It isolates and carries cloud hosts, network interfaces, routers, and related resources.

  • Subnet: An IP address range inside a VPC. Cloud hosts and network interfaces connect to subnets to obtain private IP addresses.

  • CIDR: The address range format used for a subnet, for example 192.168.2.0/24.

  • Gateway IP: The default gateway address of a subnet, usually assigned by the platform based on the subnet range.

A VPC is a private network in a region. It carries cloud hosts, network interfaces, routers, and related resources. Go to Network Service > VPC, select a region, and view the VPC list. The table displays ID / Name, Description, Status, CIDR, Created At, and Action.
