Calculating IPv4 Subnets and Hosts - CompTIA Network+ N10-007 - 1.4

- - - - -
The process of subnetting an IPv4 address can be calculated quickly with powers of two. In this video, you’ll learn how to quickly calculate the number of IP subnets and hosts per IP subnet.

Learned more things here in 9 minutes than an entire semester being taught. Thank you professor

[familyfunshots]

Thank you! I was so overloaded by subnetting that I ALMOST quit… it was so completely easy that I just couldn’t wrap my head around it. I stayed in school for 13 hours and finally bam 💥 it clicked! Thank you for you in-depth video.

Nobody explains this like you do Prof. Messer. Thanks a lot.

[unclehugo]

The comments made me feel i could understand it and yes i did, i was getting confused from other videos. Thanks prof

[jermainenaidoo]

Thank you Professor Messer, your content helps so many of us! Quality!!!

[ourspontaenousadventures.]

Thank you so much for making subnetting, my weakest part of networking, much easier to understand! You are the best!

[ssmusic]

You are a Great Professor. My confusion went away🎉

[gpassmore]

I passed my A+ core 1 and 2 because of you and this video just made me finally get the math on subnetting. Thanks mang.

[bangalagerald]

well done, i am really okay now with IP sub-netting. God bless you Prof. .

[lingon]

This is very easy to soak-in. Thanks for the video

[mikeychabie]

This will help me pass the Network+. Thanks.

[ClimaticHawk]

This is so much more clearer than my professor.

[stephanstevens]

bin trying to understand this for far longer than it should of taken through books and other resources everything just click at 6:26 awesome tutorial I didn't think id ever understand it thanks to you it all makes sense now

[TriplBBB]

what a fantastic video. You have my thanks, Professor.

[CaptainAlo]

Professor Messer, thank you very much for explaining things in a way that even someone as brainless as me can fully understand.

[teesec]

you just made me understand subnets in less than 5 minutes wow

[danielcooper]

I think I'm missing something basic here... I understand the principle and the formulas make perfect sense but I'm struggling with how you would know what the value of the subnet mask would actually be for a VLSM that you choose to use. Any help would be appreciated :)

[vijak]

Excellent, is there for IPV6 like this?

[wolfenstein]

What would be the purpose of say starting with a Class A subnet but using classless addressing to shrink the amount of hosts to that of a Class C subnet as shown in 3:30 in real world application?

[KaidenT]

Hi professor, thank you very much for your videos! I have a question, on 4:00 isnt /24 a Class C subnet making it a classful addressing instead?
