Lec-47: What is Classless Addressing (CIDR) in Hindi | CIDR vs Classful Addressing

In this video, Varun sir has explained Classless Addressing (CIDR).

Classless Inter-Domain Routing (CIDR) is an IP addressing scheme that evolved from earlier classful addressing. It is a more flexible and efficient method of allocating IP addresses. It allows more flexible allocation of IP addresses, overcoming the limitations of classful addressing.

Very well explained
A small mistake is there, while doing the AND operation to find N/W address is wrong, its should be 200.10.20.32/28 instead of 255.10.20.32/28
Its just a casual overlook done by you but the concept explained by you is amazing.

I am giving the final exams of my college and after this I'll prepare for SSC CGL, hence no link between these two. But I'll not forget the contribution of this channel in making college studies easier for students like us and a lot out there. Hats off to this man!

[deepikasharma]

i saw so many videos on subnet mask but only understand your lecture...thank you so much sir

[devashishverma]

the best video i have seen on classless addressing, hats off! before this i was clueless about masking, how to find host ID adn n/w ID etc. but he taught it so well .... THANKS again

[manishas]

You are an incredible teacher!! You have a gift because I've had such a difficult time with subnetting and your method actually gave me confidence to do this and I actually get answers right now....lol. Woohoo!! *hugs&kisses* humongous thumbs up!!

[sairajdas]

Really very clear and concise explanation. Totally satisfied. Thank you Sir.

[pritomdasradheshyam]

Very good explanation, came here when I was learning about CIDR in the AWS VPC concepts, understood the real funda of CIDR over here.

[gullu]

sir aur video bhi daldo aap ke, apke samjhane ka tareeka youtube pr sabse best h

[BuDDyLoVeU]

Sir this video is helpful to understand the CIDR concepts. In this video you (as per me) should also explain the how to find the last IP address for 200.10.20.40/28 i.e. last IP address 200.10.20.47/28. You explain only how to find the first IP address i.e. 200.10.20.32/28 for the block. As 16 IP address can be in range for that block is 200.10.20.32/28 to 200.100.20.47/28

Thank you Bhaiya. This is best video on YouTube which explains the calculation so well. God bless you.

[someotherstuffs]

Hello Sir.... Your lectures are so great! Helped me a lot in my viva! Thankyou so much😁

[world_of_programming]

the binary of 255 is and 200 is 11001000. but when we apply AND function final result will be 11001000 which is 200. So, small mistake. BUT explain Very well sir...

[kaliniyadood]

I don't understand Hindi but reading the translated text was well worth it. no fluff and straight to the point. thank you for posting.

[sadeeshadissanayake]

Hi, I'm from Sri Lanka. You are explaining everything very clearly. Always I follow your videos. But I always faced language problem. If you can, please add english subtitles or english version of lessons. Thank you! & Good Luck!

[josemorris]
