Unbinding an EIP

Releasing an EIP

Application scenarios
  • Your instance no longer requires the EIP.
  • You want to bind the EIP to another instance.

If an EIP is no longer required, you can unbind it from your instance and then release it.

Pay-per-use EIP billing
  • Billed by bandwidth: Both the EIP and its bandwidth will be billed.
  • Billed by traffic: Only the EIP will be billed.
  • Billed by shared bandwidth: Both the EIP and shared bandwidth will be billed.
  • Billed by bandwidth: Both the EIP and its bandwidth will not be billed.
  • Billed by traffic: Both the EIP and traffic will not be billed.
  • Billed by shared bandwidth: The EIP will not be billed. After the shared bandwidth is deleted, it will no longer be billed.

Yearly/Monthly EIPs are billed based on your required duration. No operations on the EIP will affect its billing.
