How to get rid of unused IP addresses?

  1. Change to the Menu Project -> Network -> Floating IPs.
  2. Select the IPv4 addresses with the Status "Down" and select "Release Floating IP" for each one of them.

With this, the IPv4 addresses will be returned into the pool which allows other users to assign the IP addresses for their VMs and routers. The IP address will no longer be billed on your account.
