Create VPC Network

Last updated: 2024-10-24 23:07:30

Overview

Private networks have region attributes. IP subnets have availability zone attributes. A private network contains at least one IP subnet. Multiple subnets can be created within a private network to divide the network. By default, IP subnets in the same private network are interconnected within the internal network.

Scenarios

Create a VPC network on the private network console page.

Directions

  1. Log in to the cloud server console.
  2. In the left navigation tree, select "Network > VPC" to jump to the private network list page. Then continue to click "New".
  1. Jump to the new private network page. According to the prompt information and parameter descriptions on the page, complete the following configuration operations.
  1. After confirming that the information is accurate, click the "OK" button. The new creation operation can be completed.

Parameters

VPC

Parameter Description
Region Select the region where the private network is located. Private networks in different regions are isolated. It is recommended to choose a region closer to your business to reduce network latency and improve access speed.
Name
  • Customized: Set the name of the private network VPC.
  • Generated automatically: If not modified, the system will generate it automatically.
IPv4 CIDR block Set the IPv4 CIDR block of the private network. After the private network is created successfully, the network CIDR block cannot be modified. Supported network CIDR block are as follows:
  • 172.31.0.0/16
Description Customized. Briefly describe the VPC to facilitate later management.

IP Subnet

Parameter Description
Name
  • Customized: Set the name of the IP subnet.
  • Generated automatically: If not modified, the system will generate it automatically.
Availability zone An availability zone refers to a physically isolated area within the same region in terms of power and network. Within the same private network, private networks between availability zones are interconnected. You can deploy each subnet in different availability zones in the private network to achieve resource disaster recovery between availability zones. You can also deploy each subnet in the same availability zone to achieve lower network latency.
IPv4 CIDR block Set the CIDR block of the subnet.
  • The network CIDR block must be within the address range of the private network and cannot overlap with the existing subnet addresses.
  • The first two and last IP addresses of each subnet network segment are system reserved addresses and are used as the network address, gateway address, and broadcast address respectively. For example, if the subnet network segment is 192.168.1.0/24, the system reserved addresses are 192.168.1.0, 192.168.1.1, and 192.168.1.255 and cannot be used.
  • After the subnet is created successfully, the network segment cannot be modified.
Description Customized. Briefly describe the IP subnet to facilitate later management.
