Thanks for this tutorial....

Everyone has different ways of learning, memorizing etc . I have found the various aspects of ip addressing to be difficult to learn, I believe the decimal to binary relationship is my achilles heel
I have found the whole series of videos helpful. ANYWAY, to all of you rocket scientist critics
who can calculate 32-29=3 in a heartbeat, the video was 6 minutes long not 60 ...barely longer than the moronic television commercials.... over and out

No disrespect for the gentleman but if you watch this video and try to understand IP addressing for the first time you will get very confused. I don't find it very helpful at all even I know this stuff and I guarantee that I'll be able to provide more easy way of understanding.

we can just calculate 2^3-2=6

Many thank you for your excellent work!

dont you know 2^3-2=6 ... your table - lol

@PCSJEFF That's true and easy enough, but that doesn't give you the lookup table that he was trying to show. If you were trying to figure out a bunch of these, it would be easy to make the table and then just quickly look at the table for the answers.
This video, compared to the others, is really bad. It will makes lost so many time. the answer is really fast and simple. you have a subnet mask of 29 and the IP address is 32.
So you have 32-29= 3 bits for the hosts.
So you calcute 2^3=8 (2 position (0 or 1) for each of the 3 bits).
Then you remove 2 because of the address of the network itself and the address of the multicast.
So you have 8-2= 6 the final answer.
To resume, to find the answer you just make:
2^3-2
