Magic Number Subnetting

[@karinasan7825]

This is by far the easiest and most modular method I have come across. Thank you so much.

Came here from Neil Anderson videos cause I needed clarification and this is one of the best explanations thus far. Thanks a bunch!

[@ProfessorS]

Glad it was helpful!

Thanks you sir. I jave heard about this method for years but never took the time to learn it. I feel this will help me a lot in the real world on my job too.

years later, and I always revisit this video when i need to remember subnetting, such an easy and simple method

[@JB-zg6ot]

Excellent explanation! The math is pretty simple. The process is also pretty simple once you see the whole picture. Relying on charts to solve for the network ID's over complicates things. Thank you for the great video and detailing the steps very clearly.

finally... I found an easy and straight explanation THX

This is a very good video, thank you

[@a90rehman]

thanks for making it man i only watch this video for subneting

[@moazelsawaf2000]

Thanks, sir ❤
Clear explanation ❤

Thank you Sir, ❤️ 🙏

If you have 4 host bits, 1 2 4 8 that means there are 15 hosts -2 for broadcast and gateway. so isn't the correct answer 13 not 14?

[@ProfessorS]

It's not 1 + 2 + 4 + 8, it's 2^4 because there are 4 bits. 2^4 - 2 gives us 14.

Professor S
My question is that e.g we have class A 10.10.10.10/24 255.255.255.0 if we calculate it through magic number method 256-255=1 how we will get Network id ?

[@ProfessorS]

At about 1:25 I talk about that a bit. If the subnet mask is all 0s or 255s, you don’t need to use the magic number method at all.

@@ProfessorS Thanks Professor oh nice.
