2004/01/20 multicast

There's a subtle difference between broadcasting and multicasting: every host on a network sees a broadcast packet, but multicast data is only picked up by the machines that WANT it. Typical uses for this are live streaming of audio or visual data.

SCO systems automatically configure a multicast route:

Routing tables
Destination      Gateway            Flags    Refs      Use  Interface          UH          3  8448275  lo0
192.168.2       UC          1        0  net0          UGHS        4       57  lo0
224           UCS         0        0  net0

See Why does this "224" route show up in netstat -r?
