How to calculate the total number of the usable host IDs?

Today my topic is how to calculate the total number of usable host IDs on a network if subnet mask is given. Any TCP/IP network has subnet mask, network ID, broadcast ID, and usable Host IDs. To calculate the total number of usable host IDs, we will use a simple formula. Understanding usable host IDs, subnet mask, broadcast ID is also the foundation for subnetting or subnetting a subnet.

Thank you so much! I finished my Network Fundamentals Class, and then got Covid... so the longer I am away from reading and studying the more information gets dumped. So I have lost about 60% of what I learned and am reteaching myself after a month of recovery. Your video was so simplistic and on target that everything just started falling into place! Thank you!

Sunny, I was really lost in my networking class until I watched your videos. Thank you very much!

Sunny, thanks my man! lol
I have a book, and other materials that I have bought to study, for my Network + Exam N10-008. Where I just needed a little bit more visual on (Calculating Host.) Your video, did the job!
Really, thank you for your efforts, and the time that you took to make this video. Much appreciated!!!

i wish i knew about your videos sooner
this is a lot easier to understand and attention grabbing than to read a text book (i guess its just my learning style)

Awesome video! This was very helpful in understanding how total IPs of a network are found. Thanks

Thanks sunny!! your video have gone a great job

no clout, your a really good professor, I come here when my other professors make 0 sense.

Dear Sir, I like your class very easy to learn for aged person who wanted to learn network quickly- I find only your class made me learn networking - best in world

Thank you sunny you are excellent. One question. Sometimes binary starts with 1 and ends with a max of 128. In this video it starts with 2 and goes to 256? Thank you

Hi what software do you use for you presentation

[wilfredocan]

many thanks for lesson, could you please brief me on the differences between Network id, Host id and Broadcast id ???

[Lucad]

Thanks so much. I have a question if I may. In the formula h = 2^ - 2 where does the first 2 comes from? Is it because of binary or something?

[golitube]

do you published a video about broadcast ID ???

[moerocco]

Where does the first 2 come from as in 2 to the x power?

I wanna know who the 18 people are who disliked this video (I just wanna talk to them)

sunny classrooms has my networking study easier, thank you so much sir

[justcurious]

what if the given Mask is on base 10, how can u calculate the total number of usable hosts ?

[DarioCruzII]

Sunny you are the best. Thank you so much.
