Hello List, I am currently trying to get a handle on understanding subnets. I'm = assuming that the basic function of subnetting is to make efficient use = of addressing and to reduce overhead in the network address tables. Is = this a correct assumption? I would also like to get your opinion on deriving the correct subnet = mask. Let's say for example that given a Class A network I want to have = 20 hosts, what is the best way to derive the correct subnet mask? I apologize if this is a little OT. This list has a lot of experience. TIA Ron ================================== To Unsubscribe, set digest or vacation mode or view archives use the below link. http://thethin.net/win2000list.cfm
