Patrick Campbell <PCampbell@xxxxxxxxxxxxxxxxxxxx> has stated that "Your subnet mask will need to be 255.255.0.0." That is the whole point. If I make the netmask as 255.255.0.0 then the point that I am trying to make is defeated. I do not want to make the netmask 255.255.0.0. I want to retain it as 255.255.255.0. Basically, it is an academic question which we were discussing in the class. I am trying to ascertain whether two class C networks can communicate amongst their network computers, through the same wire. I personally, think, they can. Because When host A wishes to talk to host C, it "ANDs" the destiation IP address with netmask and gets its own network address. So, it simply sends the message to its own network. The C computer should receive it. Same reasoning applies to other network, when B wishes to talk to D. If I change the netmask to 255.255.0.0. then it is one network. It is not two networks. So, the purpose of mixing two networks is not achieved. So, please give your comments again. With the netmask 255.255.255.0 will host A be able to talk to C and host B talk to host B. Thanks. bye shiraz __________________________________ Do you Yahoo!? Yahoo! Mail - now with 250MB free storage.
