A few reasons why you would want to know the binary is vlsm summary routes and wildcard masking that is without even thinking. cisco is a sales company so of course there tool is "The purpose of this tool is to provide a way to calculate IP subnetting which is fast, easy, and error free. Doing such calculations manually is time consuming and susceptible to common mathematical mistakes, especially in conversions between binary and decimal numbers." marvelous, :>) but they failed to mention that once you know binary you will be able to use the tool. And if they were so commited they would't allow cidr notation when configuring they mask for an address. if you look at an address in an output 24.48.45.130/26 now what do you do. ----- Original Message ----- From: "Ken" To: Sent: Wednesday, August 08, 2001 9:29 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?
