When the application deployed by the user on the CVM instance needs to provide public services, the data must be transmitted through the Internet and must have an IP address on the Internet (also called a public IP address). The Internet access provided by the cloud platform is all through the high-speed Internet in the cloud platform data center. Our domestic multi-line BGP network covers over twenty network operators, achieving second-level cross-domain switching for BGP public network exits, ensuring that your users can enjoy high-speed and secure network quality regardless of the network they use.
Public IP Address
- Overview: A public IP address is a non-reserved address on the Internet, and CVMs with public IP addresses can mutually access other computers on the Internet.
- Getting Public IP Address: When creating a CVM, set the bandwidth in the network to be greater than 0 Mbps. After completion, the Converge Cloud system will automatically assign a public IP address to the instance from the public IP address pool. This address can be changed.
- Configuration: You can log in to a CVM instance with a public IP address on the Internet and configure it accordingly.
- Conversion: The public IP address is mapped to the instance's private IP address through Network Address Translation (NAT).
- Maintenance: All public network interfaces of the cloud platform are uniformly handled by TGW. The public network interface card (NIC) of the Converge Cloud CVM instance is configured on the unified interface layer TGW, with no perception required from the CVM.
Therefore, when users check the network API information in the CVM using theifconfig (Linux)oripconfig (Windows)command, they can only see the information of the private network.
To view the public network information, users need to log in to the CVM console and navigate to the CVM list/details page.
Releasing a Public IP Address
Users cannot actively associate or release a public IP address associated with an instance.
The public IP address will be released or reallocated in the following situations:
- When terminating an instance. When a user actively terminates a pay-as-you-go instance or a monthly subscription instance expires and is terminated, Converge Cloud will release its public IP address.
- When an EIP is associated with or disassociated from the instance. When an instance is associated with an EIP, Converge Cloud will release the original public IP address of the instance. When you disassociate an instance from an EIP, a new public IP address will be automatically assigned to the instance. The original released public IP address will be returned to the public IP address pool and you will not be able to reuse it.
If you need a fixed, permanent public IP address, you can use an EIP.
