I disagree wholeheartedly with one of those statements. In this business you never really "arrive" in the first place, so the journey itself is as important or more important than the destination. You learn binary subnetting techniques for the same reason students learn math without calculators. It's important that you really understand what is occurring if you want to be a good engineer. Liken this situation to cars. If you just want to use the tools without understanding, then you are a driver only. If you want to be a mechanic and know what's happening under the hood, then you have to learn the stuff the hard way. Back to reality for a bit. As far as subnetting is concerned, it's very difficult to understand what's happening without learning it in binary. Once you've learned it, though, it's not really necessary to do it in binary because you'll have plenty of shortcuts in your head that bypass--yet still rely on--the binary math you learned previously. Just my $.02... John >>> "Ken" 8/8/01 10:29:45 AM >>> 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. The question I have is of what use is the binary math method of subnetting as compared to just using a program that does subnetting? If the point to the exercise is to produce a plan for subnetting that can then be entered into each device on the network or into a DHCP server setup, what else is achieved by doing this manually? It seems to me that the point is not the journey, but the arrival at the destination. Indeed arrival as quickly as possible, with the least source of error. As Cisco even says; "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." So what is it I am not understanding?
