- There are LOTS of protocols/applications which use multicast addressing,
- including:
- -LAT (DEC's Local Area Transport) for advertising service availability,
- etc.
- -AppleTalk uses multicasts for Zone-wide transmssion of name binding
- requests, address resolution, etc.
-
- The multicast bit is set by the device driver. As far as the sender is
- concerned, a multicast looks like any other address (except that a response
- from a multicast destination will have the individual station address of
- the responder as the source).
