I was under the false assumption that subnet masks must be identical in
length for two systems to communicate. But I do not believe this to be true.
Isn't it a fact that the addressing just has to work out so that the two
systems think they are on the same subnet?
Can someone help me with the binary math that you would do to figure this
out?
For example, let's say my router interface is
172.16.1.1/25<http://172.16.1.1/25>and I want to use /24 for all of my
clients off of that interface. What is
the quickest way to calculate the usable range of addresses for these
client?
