Private IP Address

VMRack VPS Private IP can be used for internal communication between VPS instances under the same account and located in the same data center. Data transmission is completed through the private network without generating public bandwidth traffic charges.

Compared with public network communication, private network connections provide higher transfer speeds, lower network latency, and improved security. They are suitable for various scenarios such as database synchronization, distributed cluster deployment, application service communication, and file sharing.

Features

1. Private IP Address

Each VPS supports the assignment of a private IP address for communication between VPS instances. Private IP addresses are not publicly accessible, and all data transmission is completed through the internal network without passing through public network routes.

Example

VPS instances can directly communicate with each other using private IP addresses.

2. Communication Rules

By default, VPS instances under the same account and located in the same data center can communicate with each other through private IP addresses. Private network communication does not consume public bandwidth and typically does not generate public traffic charges.

Network communication between different data centers is isolated by default and direct private network communication is not supported.

3. Private Network

VMRack is built on a high-speed internal network architecture, providing a low-latency and highly stable environment for private network communication. It is suitable for internal communication scenarios such as data synchronization, cluster communication, and database access between servers.
