You use the binary method to actually understand what is going on in the
background. I like it because now after all of the hand written binary
conversions I've done, I can subnet, summarize routes, and write access
lists that permit/block a range all in my head in no time at all. I myself
would not want to get caught in a meeting where the head boss asks "what
mask would give me x amount of host and subnets or what would summarize all
of these routes" and respond with " I have to go get my computer to do
that". I think he would be much more impressed with a response calculated in
my head or on paper right there with a clear explanation why this is the way
it is. You learn that from binary. Use the subnet calculator as a quick fix
or check. No offense, this is just my opinion.

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. 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?
