Calculate Network, Broadcast and host addresses

I love it how all of us have shit professors hence why we ended up here 😂

This makes much more sense than my 3 hour lecture. Thank you.

Another Example: Let’s say our address is 10.10.1.99/23 In Binary that becomes 00001010.00001010.00000001.01100011 The network portion is determined by the ones in the subnet mask.So /23 means the network portion is the first 23 bits as is, with the remainder of the bits set to 0 00001010.00001010.00000000.00000000 So 10.10.0.0 it the network address Broadcast address:  set those last bits to 1’s instead of 0's (everything after the 23 bits from subnet mask)00001010.00001010.00000001.11111111 So 10.10. 1.255 is the broadcast address 1st available host address – add one to the network adress00001010.00001010.00000000.00000001 So 10.10.0.1 Last available host address – subtract one from the broadcast address00001010.00001010.00000001.11111110 So 10.10.1.254 Range of host address is therefore 10.10.0.1 – 10.10.1.254

Just spent an hour with my friend trying to reverse engineer this subnetting stuff. And just wanted to say this video is what made it all click. Thanks!

Kim, I'm honestly amazed by you. Every time I don't understand something in particular, be it something about BGP, GRE..anything it is, almost always I'm missing the part that makes me go "That's it! I get it!" - I then search through numbers of books, videos, but I rarely find what I'm looking for. Then I find you!! And you always explain exactly what I've been missing and always deliver it in a way that makes me confident that I do understand a particular subject on a level that I can move on to more advanced stuff. Kim I wish you were making more videos, or had a page or something where we can ping with you more often. Thank you so much for your videos and I'd be so happy if you'd make more!!! High five!

Uni needs more people like you to teach, with clarity and simplicity...god bless you.

You've explained this simply in 4 minutes, better than my lecturers have explained in 3, 1 hour lectures. Thank you 🙏

After watching so many videos on sub-netting, I found this technique easy to understand and implement. Thanks.

3 YEARS LATER.. and this helped me out. Thanks for keeping this uploaded!

I have been struggling with this concept for a day now. You have made it clear and simple in only four minutes. Thank you! Your a lifesaver!

You just blew my mind. You summed up A LOT in just a few short minutes. It took other teachers (that I paid for) much longer to explain.

What a simple yet complete way of putting it all together. Thank you, Kim. Respect 👍

This video's explaination made me understand this concept which I was trying to get from 2 days... Thanks for such good explanation

I was totally lost on subletting until I found this video. You made it simple, thank you.

Thanks Kim. This is the most logical, easy to understand and simple way I came across in 10 years for subnetting.

That's what I was always looking for. A video with an explanation. Thanks for helping us.

Outstanding video tutorial! I’ve viewed many of these over the years and this one may be the best I’ve seen at presenting information clearly in a short amount of time.

Very useful, i watched the video one houre before the exam, you saved my day thanks :)

If you were my teacher, I would prefer to fail and repeat forever

Thanks you for making this simple video, its so clear. You explain better than the Cisco Website
