You’re an amazing teacher. I truly spent months trying to even grasp IP addressing and subnetting until I seen you’re video. Thank you.

Recently came across this guy... I love his teaching style. Thank you for making these videos, they've helped a lot!!

He sounds like Merle Dixon, He looks like Mike Ehrmantrout. He teaches like a God. Well done Sir, you helped me be more confident on my Cisco hands on exam coming up.

I have an exam coming up and both of your videos (original and latest) truly helped me clarify my confusions about subnetting. Your videos are well-organized, well-explained, and hilarious. Thank you so very very much! More power!

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.

Thank you so much. I've been doing this online course and they explained this part poorly, the first 13 minutes helped me understand what I was struggling to get! Thank you so much!

This man is a great instructor in the network field and others field of the IT.

You are a genius! I have always had issues with subnetting, even to this day and you make it look so simple. Great refresher!

This has really helped me that i took the notes that you were drawing and put them into my notebook. I've barely started a Network+ class yesterday and this is helping out!

I just came across your channel a week ago and I wish I found it sooner because this video helped a lot. Thanks.

Thanks man, Best subnetting videos i have seen. Totally get it using the methods he uses for doing the math. I get it better without using the formula and working it all out and seeing it. Now that I can picture in my head the way the numbers move, the patterns etc. Then the formula makes sense.

You are the best. Very clear, precise & methodical approach. Well done!!

Just bought your book off amazon based on your video and style of teaching. Good stuff man--started with the A+, now going at the N+ and who knows what's next. Thanks for posting and you put this info out with numbers like a (Gov) pro--don't pay attention to the negative shit, you're above it.

You look like Mike from Breaking Bad and Better Call Saul. Thanks for explaining

Thanks Laz for your time putting these together and uploading them.

Awesome video LAZ i use an app to get questions about VLSM and i work the answer all in my head and can do it all cause of your videos about subnetting.. you help me alot thanks !!!

writing my exam in just 6 hours revising now all night. College gat no sleepers wish me luck. Thank you laz

This helped me immensely to understand subnetting. Thank you.

El Jefe, just bought your book. Appreciate your videos boss !

I had to watch this 3 times to understand but now it's really simple thank you!

You are the best and scariest tutor i have found online. I love you. You probably gave me nightmares.But i understand sub-netting! I may wanna cry too.

your videos helped me to pass my MTCNA, thank you!

I would like this guy as a professor. He yells so loud, I could never fall asleep in class! haha

Thanks to you, when I'm studying/practicing subnetting I am periodically yelling out "MINUS TWO..!" I hope I don't do it during the ICND1 in a couple weeks lol

i wish to have live classroom coaching with you sir...its helped me a lot for my tests and also during placement for companies like cisco,juniper etc...you are classic....

One day I want be a master like you Doctor. I have followed you at the udemy and others channel like here on youtube. I want to purchase your book and become a little better. And who knows become a great master, like you. Thank you. Unfortunately, here in Brazil it's too expensive for me buy his book.

This gentleman is a wizard. He makes the nearly impossible look absurdly easy.

Great video, thank you for sharing! This video really clears up some things that I was unclear on.

This just made my whole weekend easier af! Thanks so much! Great, great video and super amazing explanation! Thumbs up!

Thank you so much i was so confused on the subnetting but now it look easy !! Love your videos!

Just look, listen, learn and practice...after that... every thing will be easy as 1,2,3... Awesome teaching...Mr Laz!!

Sir, I wish I had you as my CCNA instructor, my instructor really didn't teach this stuff. Hooray for education unions!!!

I love this video that cleared all my doubts of the subjects I learn😊

Really enjoyed this and your old video on subnetting. Should mention though that on the class B example, you started with a /21 and finished with a /20 somehow. Am I missing something? Thank you for the seed you are sowing into so many lives.

Thank you for the vid! Clarifies a lot of the confusion!

I love this man. He is beast in teaching. 💪

sir your teaching way is the best (Y)

Very helpful! Thank you for the in-depth explanation!

Thumbs up for awesome presentation. I have a job interview upcoming and this is great review.

good to see you Dr. Laz

Thanks lot for sharing its really help me lot.. best explanation so far...

i am soo excited learn this from you , thankyou !

I wish I would've had you as my TCP/IP professor, I would've learned this in a much shorter time.

i love listening to you sir. thank you

I just finished CCNA 3 and I'm about to start 4. Subnetting is just so scary/frustrating. Thanks for the great video.

Great session, you made it simple and easy.

This helped me A LOT! Thank you!

you are the best av come across

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

you're truly a Doctor of Networking.

Thank you for the great explanation ☺️

Awesome I finally got the concept. Thank you.

thanks pal, for any tutorial video that i have been searched for ip subneting on youtube this was the best clear and well explanation method .It help me much, for my respect I will give you +1 like and subscribe, again thanks and( btw on 19:27) you accidentally removed the vertical line than by mistake you shifting it (from8 to 16) left but never mind I know it was technical mistake and the cool is I still understand what you talking on. keep doing this pal you help a lot people awesome

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.

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?

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

His class B showed a /21 (255.255.224.0 - increments of 8) but midway he switches over to a 255.255.240.0 which is /20, working with increments of 16. I do not know how he missed that.

Thanks amigo! Great job!

now i understand subnetting......thanx to u

very well explained.

Thank you Bas Rutten

Thank you! Finaly I know how to do that ... (After 3 years :D)

ironically its the best Subnetting explanation i see on youtube

Thank you very much for this video!

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.

your biceps are getting in my way

thanks sir,I learn a lot from your video,I can pass my ccna r&s

THANKS BRO...YOU THE BEST ..I HOPE I ACE THAT TEST ON MONDAY!!

Buena Gente! Thank you for sharing!

Good Job Laz!

The best in the world!

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

wooow...very good teacher

You make subnetting a peace of cake.

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 ?

Simple and easy to understand

this feels like networking bootcamp, subnet! yes Captain Laz sir!

You are the best Thank you

What happens if they draw the line at 8 bit (last bit of Oktett),how do i know the increment number then?

I'm getting it ready in life.

thanks for the understanding

Thanks sir.respect you.

What I wanna know is simple. 192.168.0.1 to 192.168.1.255 on 255.255.0.0 that have 65534 available IP and -1 because of default ip of router 192.168.0.1. Gets my question sir? please!

Question for anyone . For the ranges you have 192.168.100.32. 33-62 are usable and 63 is the broadcast where does 192.16.100.1-31 fit at? Wouldn't that be the first network and host?

Muchas Gracias! I saw the old video earlier today but I think I got this down now. Exams on monday-

Could you please tell me what equipment you are using to get this done? Our church is trying to produce some lecture and would love to do it in this format. Would you please share your knowledge?

Lazaro you are a beast

I work on school project where I have 150 consultants that need to be able to connect to server headquaters. Does that mean that they need to have IP that is within same subnet as those servers or is it enough that they are within same network?

love the electronic white board.

why sometimes the start of counting number changes? 1,2,4,8,16... and when you count host it start with 2,4,8,16...?

incredible

As a headphone user...My ears died but I got it...thanks m8

Hi man following you around going up the ladder in subnetting, however if anyone can help me with the increments for instance 10.10.0.0 when we say increments just as an example 0-254 does it mean 0.1, 0.2, 0.3 until 254 or am missing something if anyone could point me to video or something (incrementing more than one octet i.e. class B) to refer to this video by the networking doctors "how to increment the "whats in-between" i understand everything else fine. all suggestions are welcome. thanks again.

your biceps get in my way

You did more in 32 minutes than what our teacher did for daayyyyssss xD Thanks man :D

Thank you! Thank you! Thank you!

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

Hi There. I dont understand this. My private IP 4 is 10.204.1.76 and subnet mask is 255.255.255.0..i thought ip 10.204.1.76 is class A. how is my subnet mask 255.255.255.0 that should be class C? Please give me some help on this...

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!

how can you borrow 4 bits from the network side and have a /21? if 2^4=16 to give an increment of "16," it should be /20 (8+8+1111) for the 172.16.0.0. verify that please
