Aliyun's server intranet needs to know which

　　 Intranet

At present, the Aliyun server intranet is a gigabit shared bandwidth with no special restrictions. Because it is a shared network, bandwidth speed is not guaranteed to be constant.

If you need two ECS instances of the same region to transmit data, it is generally recommended to use intranet connections. At the same time, RDS, SLB, and OSS-related intranet speeds are also a gigabit-shared environment. These products can also use the intranet to connect with each other.

At present, as long as the same region, SLB, RDS, OSS and ECS can be directly connected to the use of the intranet.

For ECS instances in the intranet:

Only the same account, the same geographical example, the default will be intranet interoperability.

The same account, the same area, the different available area intranet also interoperability, even if the intranet IP address is not the same network segment, can also be normal intranet connection.

If it is a different account, the same region, through the security group to achieve intranet interoperability, see the security group application cases.

The intranet IP address of an instance cannot be modified or replaced.

Examples of intranet and extranet do not support VIP (virtual IP) configuration.

Intranet DNS Address

Frequently encountered customers modified server DNS configuration, and then want to change back to the default but forgot the address. The following is the Aliyun line of the last geographical intranet DNS address for parameter settings to use:
