The classic network is a public network resource pool for all Tencent Cloud users. The private IPs of all CVMs are assigned by Tencent Cloud. You cannot customize IP ranges or IP addresses. The VPC with an independent, controllable and more secure access are evolved from the classic network to meet the requirements of a growing number of users for more complex services.
As the classic network resources become increasingly scarce and cannot be expanded, Tencent Cloud accounts registered after June 13, 2017, 00:00:00 can create instances (including CVM and CLB) only in a VPC rather than the classic network. If you need to use classic network service, please submit an application.
Both classic network and VPC are network spaces on the cloud.
You can use the
DescribeAccountAttributesAPI to query the network attributes of an account. If the
only-vpc, the account is a default VPC user, who owns all cloud resources under VPCs. If the
classic, the account is a default classic network user, who owns all cloud resources under the classic network.
