Understanding CIDR notation

CIDR notation, which stands for Classless Inter-Domain Routing notation, is a shorthand method used to represent IP address ranges and network prefixes. CIDR notation is used to express the number of bits in a network mask, which determines the size of a network and the number of available IP addresses.
CIDR notation consists of an IP address followed by a slash (/) and a number between 0 and 32, which represents the number of bits in the network mask. For example, the CIDR notation for a network with the IP address 192.168.1.0 and a subnet mask of 255.255.255.0 is 192.168.1.0/24, where the number 24 represents the number of bits in the subnet mask.
CIDR notation allows for more flexible and efficient allocation of IP addresses compared to the traditional class-based IP address scheme, which had predefined address blocks for different classes of networks. CIDR notation allows for smaller network prefixes, which can conserve IP addresses and provide more efficient use of network resources.
Understanding CIDR notation is important for network administrators and engineers as it is commonly used in network planning and design, IP address allocation, and routing table configuration. It enables them to effectively manage and allocate IP addresses and configure network routing protocols to ensure efficient and effective network communication.

This is the simplest available explanation in the entire internet.
It helped me a lot.
Thank you soooooo much.

[@alexisdauli8537]

Thank you sir, your video helped me to understand the CIDR notation clearly.

[@jimbakhaus5297]

Beautifully explained! I'm attending the Google IT course, and I was lost on this concept. If it wasn't for TH-cam, I wouldn't have a chance!

[@InformatikLab]

Glad it was helpful!

[@jacobalexander560]

I'm taking the same Google IT course and find the instructional videos terrible in explaining the concepts. His 6-minute video is excellent at breaking it down for a true beginner.

[@Mochi_177]

Yeah I feel like the thing this Google IT course struggles the most with is not giving examples. Not only do they not give examples, but they breeze through these topics without explaining them too well then giving such easy quiz questions it's laughable. I understand that this is a beginner course but I'd much rather have harder questions that force me to remember harder concepts or at least look up the answer so I am reminded about how to do it.

[@someoneOnYoutube001]

lol same here

[@nasaspace7212]

@@Mochi_177 seriously bro. im doing the google IT course right now. and just took my subnetting quiz and just laugh as i took it. cause im like, i can easily take this quiz and pass but if i had to explain subnet mask and cidr. my brain would go blank. youtube vids like this have been carrying my google IT education.

[@user-yj6cl3zr6v]

Thanks I'm glad when someone is actually able to show and simplify a topic such as this

[@siphelelengwenya8799]

Thanks bro, now i finally understand this concept, much appreciated.👌🙏

[@vanigolusu2408]

your explanation is clear, thankyou bro

[@TwoInfinityAndBeyond]

This video deserves more likes.

[@banksjim]

Most straightforward explanation that I've watched.

[@andrewborntrager7909]

Thank you. I finally get this.

[@d_dunk]

You made it easy to understand and went slow enough to comprehend. Thank you.

[@dannybrown317]

So straight forward thanks sir. Hope you can upload more.

[@sanyaoluadefemi3046]

This is really awesome, thanks so much

[@kurttrumble6378]

Excellent explanation. Power of two and each octet being 8 bit are key!

[@md7786]

I've watched video after video on subnetting and I get most of it. Not until this video was I actually able to understand CIDR. Thank you.

[@Jokkker84]

very well explained thank you

[@Epiclynamed]

This actually helped me understand it the best so far, thanks for the quick and to the point info!

[@InformatikLab]

Anytime, thank you for your support

[@shaikh.quadeer]

awesome covered all but in simple way

[@jebotipasmater]

Thanks, bro! Short, concise, and on point! 👍

[@7DEnergy]

I really needed this. After watching it 3 times, CIDR is easy now. Thanks bro.

[@qfficial7141]

This is EXACTLY what I needed to see!!! Thank you so much for this

[@InformatikLab]

You're so welcome!

[@firminvernege9815]

This is so simple to have confused me this long.

Thanks for the help!

[@estermartins8466]

You are the best!!!!!! I couldn't understand anything until I watch this videos and it is sooooo easy now 😅

[@maniagonewild120]

THE BEST VIDEO ON THE WEBS ON TEACHING CIDR NOTATION IN MY HONEST OPINION! THANK YOU FOR HELPING : )

[@InformatikLab]

You’re welcome

[@GuitarxWolf]

Yo! Thank you! This video finally had that click in my head understanding this! You're a master!

[@StateAlchemist7]

This lesson was so clean!! I love it.

[@OmegaRejectz]

Thank you!
It finally clicked.
I was going crazy trying to figure this out.

[@IslandGyal-ib2sv]

Thank you so much. This helped a lot!

Thanks sir

[@einedward7825]

Amazing

[@starpower776]

NICE

[@RobertAMitchell-eq8oz]

Question. Is there a way to find out the Network ID if I know the IP Address and the Subnet Mask but don't have the CIDR??

[@francoisboyer2831]

Good job Greg

[@InformatikLab]

Thank you bro, L.A.P classmate 👊🏽

[@mubirujessy4226]

How do I get the subnet address

[@yasine00]

can we automatically know the answer if its /8 or /16?

[@Techonte]

nice

[@SnapLifeShortz]

How do u get 255. 255.192.0 coz it is not understanding

[@bigyandixit]

thankyou mate never seen an African teacher in IT :D really great and wish you the best.

[@avalonerupter996]

I subbed because you explain it for DUMMIES and I'm a dummy haha

[@InformatikLab]

You're not loll, Thank you for the support

[@produceboi127]

I have 0 clue how you got 192

[@FloydBrooks]

he added 128 + 64 = 192. So in the video he pointed out that when you are adding, you start from left to right.
