IPv4 Addressing Lesson 2: Network IDs and Subnet Masks
IPv4 Addressing Lesson 2: Network IDs and Subnet Masks
Subnetting made easy | Understanding Network IDs
In this lesson on IP addressing you will learn all about Network IDs, Subnet Masks, and CIDR notation. This lesson is the second of a series of three total lessons on IP addressing which break down the IPv4 address, network IDs, subnet masks, and the IPv4 class system.

thank you for the best explanation…. finally..
what is the point of all manual calculation if there are ip subnet calculators everywhere as well as subnet reference tables
So I like the video but what seems to be missing is the correlation to a realworld network to see what all u said can mean in terms of a network/subnet structure
tanks sir!
I love you!!!!
man this video helped me so much. seriously thank you guys!
gg wp
Awesome video
Thank you finally understood damn 😊 subnetting
i fell in love with your teaching method, wonderful you deserve a clap!!!!!!
Can NextGen help me get a job if I am not a US resident or have a valid working visa?
shout out to this guy omg
The fact that I have to come to YouTube to get a better education than what I’m getting in a Univeristy is crazy. I got so confused in my lectures that I had to come here to actually figure out what to do. Big thanks man!
I literally learned this so fast because of your video 😂
This threw me for a loop when he used a class B subnet mask (customizing the 3rd byte to make it under 255.255.255.0) for a class C IP address at 5:26. The network portion of the subnet mask never changes; hence why we have classes. The classes define which part of the IP address are the network portion as opposed to which bytes can be allocated to the subnet and hosts. The lowest CIDR for a class C IP address is /24, so having a /21 on a class C IP address is not plausible and would be an error. Slight overlook but sort of worked to teach the concept.
Ok guys
wonderful explanation, thanks a lot.
Wonderful video, thank you so much.
THIS! This made it all make sense to me. This video taught me things that the CompTIA Certmaster Learning Plan didn’t tell me. I was confused so I came to this video and it showed me the way! Thank you
AMAZING, thank you !
Just one word…… Fantabulous
Is there a way I can find the subnet mask without using the CIDR method?
thank u that was super helpful
THANK YOU! you really saved me one day before the exams haha
I could not get my head around this until now! Thank you for making it so simple!
Very helpful! Thank You
Added this to Plex.
To find usable host. 255-192= 63, 63-1, since first address is use for broadcasting. So, you have 62 usable hosts
Channels like this are my real teacher
Traductor a español
Pliss
Thank you so much. you solved one of my biggest problems 🙂 with this video. you explained so good.
It is Good leactures thank you again and again
This video was really good. I have watched many videos on subnetting, and neither those videos or my lectures in college have made it understandable for me. But with these videos it has become a lot clearer. Thank you!
This helped a lot thanks 🙂
Explained like a Pro.
thank you very much
I never understood subnetting until this. And I’ve seen alot of videos 😅
How do we work out the mask just using the IP address?
Thank you Love you:)
Właśnie ta konfiguracja działa mi tylko na ustawieniach sieciowych Windows 10 Phone i Windows 10 a na Windows 11 Cumulative 🆕 nie chce mi działać i nie pozwala na aktualizowanie Windows 11 Cumulative 🆕.
Omggg I FINALLLY GET IT!! LOL thank you SO MUCH dude I’ve really been struggling with this whole concept in class ❤️👏😆
starting off hard was a good idea?
you literally make me want to learn. Thanks man
Excellent presentation, clear and to the point. Many thanks!
THANK YOU! This is one of the best videos explaining subnetting for newbies like me. lol!
Thank you! Thank you! Thank you!
FUCK THIS BULLSHIT!
Great video very easy to understand I got it on the first example
Great video helped a lot
Amazing thx
