    <title>About Portable IP</title>
    <para>Portable IPs in &PRODUCT; are region-level pool of IPs, which are elastic in nature, that
      can be transferred across geographically separated zones. As an administrator, you can
      provision a pool of portable IPs at region level and are available for user consumption. The
      users can acquire portable IPs if admin has provisioned portable public IPs at the region
      level they are part of. These IPs can be use for any service within an advanced zone. You can
      also use portable IPs for EIP services in basic zones. </para>
