• Awesome man! It helped me lot and keep the good work up.

• Thank you so much! Just started my classes and my professor isn’t the best at explaining but this has made it so much easier to understand.

• Shouldn't you take away 3 since we also reserve an address for the default gateway, broadcast and router?

• Thanks from Pakistan lol you really helped me and answered exactly what i was looking for.

• Thanks 🙏🏻

• Excellent!

• Wow this is a fantasic approach to teaching subnetting! Ive learnt a lot from this video. Thank you!

• well done

• I had to sub cuz i had been struggling to make sense of this. more practice and it may even be fun 🥲

  Thank you for your effort in getting us to understand this material. i know if it clicks for me after watching this, it'll help anyone.

• At 1:21 where valid hosts the formula is 2^ #of host bits -2
  i think i should be 2^# of host bits -3
  because you cannot use getway ip address like network and broadcast ip

• Hello….
  IAm…new friend 😇🥳😍

• What if ur mask is /16 with a class A ip address?

• Thanks that is why my psychiatrist told me I can't know reality and I thought she was kidding

• The address now sometime long as a river

• thank you sir

• THANK YOU!!!!!!!!!!!!!

• Nicely explained

• Class c

• in the 2nd exampel how could you say its a b class while the SNM is 30? it is a C class network.

• AliAli

• kat sini ke siakk

• Perfect explanation. You should just explain a little bit more about what those numbers are in the parentheses after the subnet mask. They are the number of ones.

• Excellent! Thank you!

• thanks helped a lot

• THanks man
