Starting the days of coaxial ethernet (10Base2/10Base5) there was a
limitation per subnet of :

   * five cable segments, connected by
   * four repeaters, but only
   * three segments coule be populated.

This hasn't been updated to 'modern day' technology of switches and
bridges (which change the rules somewhat).
