alias Establish an additional network address for this interface.
      This is sometimes useful when changing network numbers, and one
      wishes to accept packets addressed to the old interface. If the
      address is on the same subnet as the first network address for
      this interface, a non-conflicting netmask must be given.
      Usually 0xffffffff is most appropriate.
