It *appears* from what I have been able to gather that there is a
broadcast address that I can send to, consisting of the highest IP
number in the allowable range, ie, 192.168.1.255 for that ip range.
In general, computers use the mask of the netmask and the IP address
to get the range. The lowest value and the highest value in that
range are usually broadcast addresses, but to be nice, you should
always use the highest.
If you have a netmask of 255.255.255.0, then the 192.168.1.255 is a
fine broadcast address. however, if you are like most home users,
then your netmask is either 255.255.255.248 or even more restrictive.
In those cases you will not end with a 255. On the flip side, if you
are a large site, you may be on a class B or class A network. Then
you may have a broadcast address that hits quite a few machines.
I say in general because there is always the wacky set up that does
not have a broadcast address.
