Understanding CIDR Ranges and dividing networks

Very brief explanation of network subnet with the / notation

[@HarshKapadia]

Nice video! Thank you or much so much!
At 4:41, the 2nd IP should be 192.168.1.190, as 191 will be reserved for broadcasting, right?
Justification:
128 + 64 = 192 (start of 2nd half)
128 to 192 (both inclusive) is 65 addresses, so 128 to 191 is the range for the 1st half.
The 2nd half will range from 192 to 255 both inclusive, which is 64 addresses.

the BEST EXPLANATION of CIDR subnetting i've come across!! Thank you so much for this easy to understand breakdown, Jose.😀

[@liorbarkai1674]

Finally a simple and clear explanation even someone like me can understand :) thank you very much for this video!

[@somedude2734]

Excellent, thank you Jose! Exactly what I needed, straight to the point and easy to understand. Now I do.

[@manishkataria1]

thanks for posting this, it really helped me. That's what I was looking for.

[@ec92009y]

At 5:45, I would think the subnet 192.168.1.128/26 starts at 192.168.1.129 and ends at 192.168.1.190 (not 191 which IS the broadcast address).

[@HarshKapadia]

Exactly.

[@SagarAjmire1]

I calculated 4-5 times because of this.

[@brandonsmith666]

this fucked me up big time. i can’t trust this video…

[@happykillfreak]

I'm having a hard time wrapping my head around CIDR for AWS VPC until I saw your video. Gee thanks! You're definitely a lifesaver.

[@jbravovideos]

thanks!!!

[@zulkifal111]

Awesome-very well explained- i have been thru many videos ,always challenged and not understanding -this video was indeed the best on cidr - thanks so much Jose

[@jbravovideos]

Glad it helped

[@jbravovideos]

Thanks for your kind words, and God bless us all.

[@ericsmith5150]

It's amazing how you simply stated in a mere of seconds what others do for a full min or two on this topic the key to understanding CIDR is ip4=32 bits

[@jbravovideos]

Thanks!!!!

[@jbravovideos]

Quite welcome, thanks for taking the time to write

[@methembethomastshuma9587]

you are a beautiful man

[@tnndll4294]

This method works when your ip has the "192.168.1.x" format.
but if it's something like 10.1.0.0/16 or 172.16.100.0/24 - it doesn't work.
This is what's frustrating about youtube networking videos, they don't give enough examples.

[@ananshnawang2360]

Watch this video, It has class A address Subnetting example,
Your doubt would clear up!!!!

[@JayLucM]

At 4:42 in the video The Usable IP range should start at 192.168.1.129 and ends at 192.168.1.190 (not 191)

[@HarshKapadia]

Yup!

This broke this down so well. I've been searching all over. But do people really know 2^n in their heads? Or is it memorized?

[@RAJESHKANOJIYA]

Well explained 🙏🙏🙏

[@mosetanielu5685]

why did you add +1 to 25 @4.08?? why ddnt you do the same with the previous example? confused man

[@shabarismith]

Thanks for this video, clear explanation

[@manishkataria1]

i have a question, suppose the CIDR is 192.168.1.200/16, does that mean the first IP address will be 192.168.1.201?
www.ipaddressguide.com/cidr shows that first IP will be 192.168.1.0. Why is that so? if this web page is correct, then there is no differece between 192.168.1.200/16 and 192.168.1.190/16 as for both, the first IP will be 192.168.1.0

[@raamakirtinan.s7331]

Perfect this explanation made me clear. Thanks for ur post

[@1rk1n]

Im sure the concepts you are teaching are sound, but it's helpful to write what you're saying, at least for me...

[@pallavkan]

just to add this is a class C network hence 24 bit for n/w and 1 for host!
Class A -> 1 octet for N/w and 3 octet for host
Class B -> 2 octet for N/W and 2 for host
Class C-> 3 octet for N/W and 1 for host.
Simple way to remember A-1, B-2, C-3

[@jbravovideos]

Great

[@nirmaltripathy3226]

[@sent3nza]

Why this standard. Why don't use just /64 to intend 64 IPs or /32 if I want a 32 range of IPs?? I don't get it.

[@clotildesirri5534]

All I can say is FINALLY!

[@NeoYOYO173]

How the heck to to break into 2 subnets . What is the math behind that?

[@IbraheemKhazbak]

using more routers where each router gets a part of the network
