Subnet Mask chart


This is a very handful chart. Other day my friend just brought up a problem for which I answered using Supernetting.

Which, at the end turned out to be wrong  and I concluded that I had kind of forgotten about subnetting.

Later that night I grabbed TCP/IP – Behrouz A. Forouzan and revised my concepts about subnetting. And hence I thought of making this chart.

    Forouzan has very detailed concepts. Very very useful book. Thanks for this chart. It is very useful for me too :)

    Your /19 A Class available Subnet number is wrong. It should be 2048 not 2046.
