Hello Sir, I want to thank you from the bottom of my heart for teaching me how to subnet. I looked at numerous of videos and it seemed like all of these instructors that was teaching subnetting on youtube was making it confusing for me. When i look at this video and your original video "IP Addresses and Subnetting" i quickly understand the information that you laid out and couldn't believe how easy you made subnetting for me sir. Thank you, Thank you. You are a great instructor.

You moved your line right at around 19 minutes and 20 seconds changing your increments. Which increment is right? I imagine it is 8 before you changed it back to 16.

good to see you Dr. Laz

I'm kinda glad that you changed up on the Class B midway through... It forced me to think!..Thank you.

I can subnet when I write it all out, but trying to do it in my head beyond 3 subnets seems to be beyond my ancient brain ;) Serious props to anyone who can do this in their head under pressure. We have a set time to do the Cisco practical exam, and I'm eternally grateful that my income doesn't depend on my ability to spit out subnets given 'x' hosts on a given network : I find myself second-guessing even the simplest arithmetic.

LAZ, I am asking this for my understanding, I know I could be wrong here but you want us to ask questions and gain understanding. On the class B example, I think you moved your line from 5 bits on to 4 bits on making it ultimately a /20. Because based on /21 wouldn't it have incremented by 8 instead of 16. I am asking for my understanding and if I need a digital slap, I am OK with that. Thank you. By the way, I am going to do your updated CCNA course once I get home. Currently, I am re-reading your book, The only IP Book You Will Ever Need! Subnet masking is where I have to keep practicing and get that clear.

a big fun of you ,,,which technology you are using ? is it a tv or smart board you are writing on ?

you are the best av come across

is that possible that 192.168.0.52 and 192.168.1.234 is in the same network? by using class B 255.255.0.0?

You make subnetting a peace of cake.

Hi thanks for helping me learn subnetting. I have question: You want to design a subnet mask for 172.29.00 for example. you want 30 subnets with up to 1900 host. what subnet do you use? following what you have said. i can use 255.255.252.0 which gives me 64 subnets and 2048 hosts or 255.255.248.0 which give me 32 sub and 4096 host. firstly am i correct and secondly and if yes which one do you use? are the subnets more important that the host in this questions? looking at the question do we count the host first and what ever the host are or the other way around. Again thank you so much for making this easy!!!! and yes your biceps do get in the way lol

I'm starting to make sense of this now - thanks for the tutorial's.

Thank you! It really helps me lot, but i have a question. I'm a bit confusing. for example Network ID of 195.187.86.0 and the Subnets Required is 44. What is the Subnet mask, 1st available host address of SN1 and max # of host/subnet. Can you please make a simple solution for this. Thank you very much!

@michaelkusjanovic9954

7 жыл бұрын

If I understand it correctly: subnet mask is /30 (255.255.255.252) - first available host in subnet 1 is 195.187.86.1 - and the max number of usable hosts per subnet is 2.

what exactly happens when a range is full from hosts on the network....is it the next host that attempts to connect..say into a wifi network simply cannot connect? Is there something tells them they are out of the range ?

This made me feel like if Dwayne Johnson was my math teacher and IT networking teacher😂😂😂
