Broadcast address parameters
All datagrams sent by TCP/IP move through all machines in the network path.
However, each host adapter ignores any packet that does not include that
particular computer's IP address in the datagram header. Occasionally,
you might want to send a message to all machines on a particular network.
To do so, select a ``broadcast address'' for your machine. A broadcast
address is one in which the host portion of the IP address consists
either of all 0's or all 255's.
The configuration procedure prompts you to
choose between these address schemes:
Table A-4 Broadcast address schemes
--------------------------------------------------------------------- Scheme Example Purpose --------------------------------------------------------------------- all zeroes (decimal 10.0.0.0 provides compatibility with 0) 4.2BSD systems all ones (decimal 10.0.255.255 UNIX Operating System Standard 255) (RFC-919)The addresses shown in the previous table are for a class B network, and are shown as examples only; your values will be different. If you are on a network that does not contain any machines running 4.2BSD systems or earlier BSD versions, choose all ones. If such machines exist on your network, choose all zeroes.
