Overview
The Elastic IP (EIP) service provides independent public IP addresses and outbound bandwidths for Internet access. If a FlexusX instance has an EIP bound, it can access the Internet. If a FlexusX instance only has a private IP address, it cannot access the Internet. You can purchase an EIP along with a FlexusX instance or purchase an EIP separately on the EIP console and bind it to a FlexusX instance you have purchased.
The EIP used by a FlexusX instance supports the following functions:
- The EIP can be bound to or unbound from the FlexusX instance.
- IPv6 is supported.
- The bandwidth size can be changed.
- If you have released EIPs, the system preferentially assigns EIPs from the ones you released in the last 24 hours.
If you do not want an EIP that you have released, it is recommended that you buy another EIP first and then release the one that you do not need.
For details, see What Is Elastic IP?
Billing
- EIPs used by FlexusX instances can be billed on a yearly/monthly or pay-per-use basis.
- EIPs can be billed by bandwidth, traffic, or shared bandwidth.
Constraints
- If a FlexusX instance needs to access the Internet, bind an EIP to the instance.
- EIPs are regional resources. It cannot be used across regions or accounts. Each EIP can be used by only one FlexusX instance at a time, and they must be in the same region.
For more EIP constraints, see Notes and Constraints.

Binding an EIP |
You can bind an EIP to a FlexusX instance so that the instance can access the Internet. |
|
|
Unbinding an EIP |
If your FlexusX instance does not need to access the Internet or you want to change an EIP, you can unbind the EIP from the instance. |
|
|
Changing an EIP |
You cannot directly change the EIP of a FlexusX instance. To change the EIP, you can unbind the exiting EIP and bind a new one to the instance. |
|
|
Modifying a bandwidth |
You can modify the name, billing mode, and size of a bandwidth. |
|
|
Releasing an EIP |
After an EIP is unbound, it is still billed. If you no longer need the EIP, release it in a timely manner. |
