    description:
      - parameter that will define the behavior for the ip address status.
      - If "interface" is used, only one IP will be allowed per interface.
        The "state" parameter will define if the IP is added, edited or
        removed. No settings options are required to removed the IP from an
        interface
      - If "address" is used, and interface will be able to have multiple IPs,
        but address will only be added or removed. In order to change an IP, it
        will have to be first removed and then added to the interface in two
        tasks.
