Ive been working with NT for years, and TCP/IP just as long... Developing sites and deployments... I personally learned subnetting through binary, and have gotten to the point that I can calculate quickly in my head... now this to me is even quicker than opening some program, typing in a few figures, and getting the answer... Most people probobly use the calcs etc, but the idea is to make sure you have an understanding. When going to a client site, and looking at the way their subnets are set up, I think it is essential to be able to glance at the environment, and have a good idea if there are any mis configurations of subnetting. this could quickly rule out something we might not catch right away... Especially using VLSM... some may never get to that point, and thats ok too, but you can probobly add 1+1 faster than you can type it in on a calc.. ----- Original Message ----- From: Ken To: Sent: Wednesday, August 08, 2001 11:29 AM Subject: Why Should the Binary Math Method Be Used to Subnet [7:15306] > This is a study group so I have a question for which I need some education. > I am not looking for a flame war, just education.

So what is it I am not understanding?
