Private network services are LAN services, where cloud services can access each other through internal linkages. Tencent Cloud services can access each other through internet access or the private network of Tencent Cloud. Tencent Cloud data centers are interconnected with underlying networks of megabytes/gigabytes. They enable communications via private networks with large bandwidth and low latency, which are free of charge if in the same region to help you build a network architecture flexibly.
Private IPs are addresses that cannot be accessed through the Internet. Each instance has a default network interface (i.e., eth0) for assigning private IPs. Private IPs can be automatically assigned by Tencent Cloud, or you can specify on your own (only for VPC environment).
If you change the private IP within the operating system, the private network may be interrupted.
Private IP can be used for the communication between CLBs and CVM instances, and between CVM instances and other Tencent Cloud services (such as TencentDB).
Each CVM instance is assigned a default private IP address upon the launch. The private IP varies by the network environment:
Private network DNS service is used for domain name resolution. If DNS is configured incorrectly, domain name cannot be accessed.
Tencent Cloud provides reliable private network DNS servers in different regions. Specific configurations are shown below:
