Comments on 'Cisco Training CCNA IP Addressing - Part 6'

1. This is great. Makes me want to learn more from your videos.
   Everything sinks in after the second watch.
2. Thanks for the post.
3. Thanks for your videos! Your explanations actuallly make
   sense! This method is great!
4. Great tip; kudos!
5. It would because 256 is the highest amount of address
   possibilities in one octet: (0 to 255 from all 0s to all
   1s). As in the vid, same deal goes with any masking (check
   equation below): possible octet bits - masked bits = host
   bits. e.g. 256 - 248 = 8 256 - 240 = 16 256 - 224 = 32 256
   - 192 = 64 256 - 128 = 128 etc...
6. will 256 work with all subnet masks to determine the subnet
   host ranges and broadcast addresses?
7. thank you very much keep going u make a great job /
8. Thanks for the tip. I'm reading a book and it says to use
   the magic number where you draw a line between the network
   bits and the host bits and look at the network bit next to
   the line. You look at the place value of that bit to see
   what the increments of the subnets will be. It works, but
   you still have to write out the binary value of the octet.
   Your way is much faster.
