Huh? You can use any netmask with any 'class' IP net, as long as all parts of the attached net share the same settings. In the case of assigned private IP ranges (10.*.*.*, 192.168.*.* etc.), this means that the netmask must only be the same in your network - those addresses are not routed in the internet. I think it is quite common to use an assigned Class B net and use it as a lot of Class C nets (our university does this, too). Regarding routing: you are routing the whole network that is defined by your netmask. If the Class C network you are using (eg. 10.0.0.*) falls in a Class A block or not does not matter - you are using a network using a 24/8 bit netmask, and you are routing all of that - no computer uses the knowledge that this used to be a class A block for routing purposes. cu Michael -- Michael Schwingen, Ahornstrasse 36, 52074 Aachen
