Re: What exactly is a netmask? (Score 1)

You are right; but don't quite right. Yes, hosts on your network will have IP addresses from 192.168.0.1 to 192.168.0.254 (not .255, there will not be any packets from .255 normally). But any other address may be used in IP header, and your host will still be receiving those packets.

It seemes that you have "empirical" knowledge from using Microsoft systems. Nice, but not enough for network admin.
