Changing an EIP

Scenarios

You can change the EIP bound to your ECS as needed.

Currently, the EIP bound to the ECS cannot be directly replaced. You need to unbind the EIP first and then bind a new one to the ECS.

If there are no available EIPs, assign one first.

Before replacing an EIP, evaluate the impact on services to prevent network interruption.

Constraints

If an EIP is released by mistake, the system will preferentially assign you an EIP that you have released in the last 24 hours.

If you want to bind a new EIP to your ECS, you are advised to allocate one first before unbinding the original EIP.

Unbinding an EIP

1. Log in to the management console.
2. Locate the row containing the target ECS and choose More > Manage Network > Unbind EIP in the Operation column.
3. Confirm the displayed information and click OK.

Binding a New EIP

1. Log in to the management console.
2. Locate the row containing the target ECS and choose More > Manage Network > Bind EIP in the Operation column.
3. Select the desired EIP and click OK.
   

   If no EIP is available in the current region, the EIP list is empty. In such a case, assign an EIP and then bind it.
