This article is to share with you about the role of private network ip of CVM. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

What is the use of private network ip of CVM? The address of the intranet is the local area network (LAN). The CVMs in the intranet access each other through the internal link. Private network IP address is an IP address that cannot be accessed through Internet. It is the implementation form of private network service of cloud service provider. Private network addresses can be automatically assigned by CVM providers or customized by users (in a VPC environment). However, changing the intranet address within the operating system will lead to the interruption of intranet communication.

The private network IP of CVM can be the same in different Lans, and the private network ip cannot be used for domain name resolution. It cannot be used for remote login of CVM directly. Its main function is to communicate with other machines in the same cluster under the current account.

General CVM products can be accessed through Internet or via private network addresses. Intranet communication service is basically free in the same region, which can help users to build network architecture flexibly.

Computers on the intranet can send connection requests to other computers on the Internet, but other computers on the Internet cannot send connection requests to computers on the intranet.

Some small businesses or schools usually apply for a fixed IP address and then use the entire company or school machine to access the Internet through IP sharing (IP Sharing). The IP address used by the machines of these enterprises or schools is the intranet IP. When planning the IPv4 protocol, the intranet IP specially designed a private IP address (or reserved address) for the intranet taking into account the possible shortage of IP address resources.
