When we learn about Ali CVM or other brands of CVM, we will see the concepts of public ip and private ip. Here we introduce the difference between public ip and private ip of CVM.

In general, the public IP address is the IP address given by ISP (that is, network operators such as telecommunications). The private IP address is the IP address set and assigned by our local area network.

Public address

It is the responsibility of Inter NIC (Internet Network Information Center Internet Information Center). These IP addresses are assigned to organizations that register and apply to Inter NIC, and the public IP is globally unique, through which it has direct access to the Internet (direct access). A public IP address is a number that allows two computers to recognize each other. When connecting to the Internet, the user's computer is usually assigned an address by ISP (Internet Service provider).

To set up an enterprise network, you need to apply to the "telecom operator ISP" for a broadband access to Internet. At the same time, ISP will also assign us one or more IP addresses, these IP addresses can be used for our internal Internet access. The IP assigned to us by these ISP is the public IP.

Private address

It belongs to an unregistered address and is intended for use within an organization, that is, private IP cannot be accessed directly. A private network can be formed when many devices are connected to each other wirelessly or wirelessly. Although addresses in private networks must be unique, different networks can use the same address. The broadband we run is accessed through the router, and the IP address used is the private IP address, and the device of the router uses the private IP address to transmit data between the connected computers.
