IP Addresses Explained | Cisco CCNA 200-301

[@cafxne]

I've been studying networking for 3 years, never got the hang of it. I have an exam tomorrow at 9am. It is currently 11pm and I just found your channel, watched 3 videos so far and understood everything. You might be my saving grace! Thank you!

[@cafxne]

Hi, ended up with a JavaScript question, so sadly I couldn't use my newfound networking knowledge, but thank you nevertheless 😁

[@aadilkp5335]

Something is really attractive about your videos, the smoothness and simplicity in animations and colour schemes I think.. You will definitely succeed! Keep up the good work

[@Certbros]

Wow, thank you! Really appreciate the comment. Great to hear you liked the videos!

[@ramansharma1953]

Class A IP addresses (0-127 NOT 126), where the 1st bit is 0, encompass the range of 0.0. 0.0 to 127.255. 255.255. This class is for large networks and has 8 bits for network and 24 bits for hosts GREAT CONTENT CERTBROS ! THANKS

[@Mangokyaw]

i was so confused on that, thanks for the explanation. and @7:20 how did you know that each class has how many host numbers?

[@user-yj7tj4mf2tv]

an error to correct,it's 7 bits for the network,bro .thanks for the hint !

[@alexgarett5195]

I teach this same method to freshmen and non-traditional. The difference is visually u do a much better job!!! So note 2 ppl reading this, I would check out his feed. Thank you for doing this, it takes a lot of work.

[@built4u2]

Thanks really helping me with my networking class where the teacher just has us read the book the whole time!

[@mariannna3]

I literally paid for a whole course on networking elsewhere and somehow I cannot bear to open that course. Instead here I am on your videos during my leisure time. Your videos are very well made and something about the layout is just captivating 👌 Thank you!! And please make more videos! 😊

[@aryaswolves]

Thank you so much! im currently taking Cybersecurity class and the coarse is all over the place, this video helps put everything in perspective. Much appreciate it!

[@Certbros]

Thank you Bernet! Good luck with the course! I'll be making some cyber security related videos soon!

[@McNasty_619]

I've watched several different videos on topics covered in the CCNA 200-301 exam and I am very pleased (so far) with the content provided by CertBros! The content and information provided feels relevant, up to date, and coincides with the information provided on the text book for the CCNA 200-301. The content provided is helping refining the information that I am learning in the book as well giving me a secondary insight and broadening my perspective on Networking in general. I look forward to listening in to all the content provided as I grind out the text to get my certification! Also the 99 problems shirt is funny AF! lol

[@Certbros]

Wow! Thanks for taking the time to write such a great comment Mark! Really glad to hear you're enjoying the content.

[@sararisotti6106]

I appreciate the simple class difference between A-C explanation, thank you

[@roweldavid4952]

This is helpful for me as a teacher, to explain complex subject in a very simple manner. You are a king of Simplicity.

[@Certbros]

That's really great to hear Ruel! Glad you found the video helpful.

[@nobodycaresaboutyou5590]

watching all your videos before exams

[@USAF305]

Thanks a lot I am a IP student but the way you explained it gave me a better understanding from what I learned in class

[@ADAPTATION7]

I love the analogy. Analogies make abstract ideas so much clearer.

[@Certbros]

Glad you liked it!

[@gamesappscracked8311]

i didnt believe there is something perfect until i watched this !!! this tuts should be official source of networking... keep up the good work !

[@Certbros]

Great to hear! 🙏 perfect might be taking it a little far though haha.

[@nauticaorangewatchbg9923]

Im really struggling to understand computer networking, but this video really helped me as you would teach a kid in elementary school. Very good. Subscribed.

[@croitoruradu4878]

Finally somebody who's not indian and knows really well how to keep things as simple as possible for a better understanding. Congrats and cheers.

[@Certbros]

Thanks! Glad you like the videos.

no need to be rude they know what they are doin

[@fudoshin2776]

Your are an absolute Legend for making this. Thank you so much!!! I didn’t even have to pause or go back 10 seconds I understood everything

[@Certbros]

Thanks for the comment Zee! Great to hear you liked it.

[@ronthedon3106]

I get it but I just can't seem to put it in real world scenario also who is setting all theses addresses.. I need a real world example

[@olafzijnbuis]

Very clear explanation. About as simple as the official RFC documents. I was just reading the one describing IP. I love the simple ASCII graphics they used. Your animations and diagrams are also superb.

[@Spaniards56]

Finally I found someone clearing up the reason WHY not bigger than 255 in an IP address. The course I am taking simply say between zero and 255

[@Certbros]

Glad to help Flavio!

[@nilufarbagherzadeh8157]

[@annm.8231]

Again thank you. Where were you 2 years ago when I first started. You are a teacher!!

[@johndripper]

An IP address is made up of 4 octets. each octet is 8bits long so 32 bits in total. So to calculate the number of hosts supported by a particular class we use - class A: (2^24)-2 = 16777214 class B: (2^16)-2 = 65534 class C: (2^8)-2 = 254 subtracting 2 because network id and brodcast id are reserved

[@pauljohn3792]

Thanks

[@nassim2799]

thanks i was trying to figure out how did he calculate that number.

this helped me so much my professor literally couldnt explain it as well as you thanks for the explanation

[@barbobrien9318]

Lesson pacing and explanation exceed expectations. Thanks.

[@RandomShowerThoughts]

doing some review, and this is one of the cleanest explanations i've seen since learning this

[@itaybarok9405]

Wow the comparation between the houses on streets to computers on LAN was valueable. Thanks! I got a better intuitive feeling of the concept. Also I learned new thing such as this classes. I have a question for you, is this classification into classes useful? Thank you for this online short video it was done well so well done. Keep doing this.

[@Certbros]

Classes can be useful when dealing with simple or defualt configurations but we are no longer restricted by them.

[@Randumb96]

That was a really clear way to explain a complex subject!

[@RaphaelMandah-wq4cf]

thank you for this, your contents are well explained and easy to grasp and follow. I'm kind of a slow learner, this is helping me a lot!

[@soufianetaoufik7830]

Dude, you were born to be a teacher, when are you dropping the course ???

[@sudeeproy266]

You should have added few lines on loop back address cause some may get confused what happened to 127.x.x.x. Other than that great video. Really helpful.

[@Certbros]

Thanks! Yep, I've had a few questions about that. Next time I update this video I will definitely include it. Great feedback, thanks again! 👍

[@ibrahimwahab9801]

This is one of the best explanation I could get on IP.

[@aaha2017]

thank you for the video. at 8:06, shouldn't it be like the following? Class A: 1.x.x.x - 126.x.x.x Class B: 128.x.x.x - 191.x.x.x Class C: 192.x.x.x - 223.x.x.x
