Hi!
Follow this step-by-step tutorial how to draw and use the subnetting chart table.
Previous (introductory) video is done but requires a bit of 'post-production' :-) be back soon to watch it!

And as a bonus (or an aid) below you can find a link to a ready to use Chart Table file:

Thank you!

EDIT:
I know lots of you were looking for the introductory video - I must say with regret, that I never managed to finish it, and as the time goes by, it's more and more difficult to... even find the source files with the videos...
I may try to do one more approach to that in future and let's hope that this time we'll see the final result here :)
However, be aware, I don't promise anything - I'm just busy with other things, mostly - family :)

Thank you all for kind comment - and good luck in the exam(s)!

EDIT 2:
Download link for the subnetting chart is fixed.
