Subnet Saturday #1: IPv4 Basics | Cisco CCNA 200-301

[@slothnobody7609]

I just say a huge thank you! I never could grasp the concept of Subnetting before. And was afraid I might not be able to continue with the Cybersecurity field if I couldn't figure it out. So, I just want say thank you so much for breaking it down like this. The rulers and the 5 basic steps (hand) really helped me connect some of the dots in my mind. Look forward to checking out more of your subnetting and other helpful networking tips and tricks.

[@KeithBarker]

Music to my ears. Glad it was useful, and thanks for the feedback! Happy Cybersecurity studies!

[@manuelaraica3216]

This is a very fun learning and nobody explains it better than Keith. This foundation will serve us great for the life of our IT career.

[@KeithBarker]

Thank you Manuel Araica!

[@ChasedWheels]

Oh man, teaching IP addresses using the ruler was simply an awesome idea. I had never seen someone explaining like that. thanks

[@KeithBarker]

Glad it was helpful!

[@luisgutierrez5351]

Keith, I have clicked on a couple of your videos here and there while looking at how to do a task but have never finished the videos BUT now that I'm actually enrolled in school for a few IT certification and got stuck in IP subnetting.... did some research and ran across a recommendation from a post I read in "Reddit". As of today, you have just become my #1 instructor for the CCNA. I just finished watching the IPv4 Basic and I'm hooked. I'm so excited that you have the whole CCNA series...over 175+ videos. Thanks for putting out these videos and thanks a million for all that you do for the network community.

[@KeithBarker]

Thank you @luisgutierrez5351!

[@jeyamariyappanmv135]

Indeed great session. Crystal clear explanation. Will never forget those 5 😂 4 nos,3 periods,2 components 😎

Your way of teaching is not only fun to look at and listen to but also the most effective I've seen. Thanks Keith!! Love these videos!

[@KeithBarker]

Thank you Karim Bizid!

[@FTroop37F]

Great stuff....thank you. I wish I had found you 15 years ago. You're a good instructor. Your enthusiasm is contagous and it's clear that you've put a lot of time and effort into how to best deliver the info. The use of rulers really illustrates your point well, and quickly. I love the home-made, telescopic, color coded subnet mask teaching aid. Good on you for what you're doing to help people here on KZbin...for free. I'm subscribing and have already visited CBTNuggets....which I would never have found if not for your free content. Thank you

[@KeithBarker]

Thank you FTroop37Foxtrot!

[@RT-kk2gk]

Keith you are the one who makes Network stuffs very easy and interesting !I am thankful that I found your Chanel. Thanks and keep it up.

[@KeithBarker]

Welcome aboard!

[@scarvado6752]

I've learnt this by my own before coming here, but believe me dude u have been the only person that had explained this so clear, and direct to the Point, when I was looking for a good understanding of this topic I wish I could seen you before, anyway ppl this guy ROCKS!! Greatings from Nicaragua you have gainend a new subscriber!! Blessings!!

[@KeithBarker]

Great to hear!

Being into Networking.. I still find this is so far the finest way to make one understand. Thank you keith

[@KeithBarker]

Thank you Gaurav Desai, welcome!

[@samueldarenskiy6893]

Hands down best explanation of subnetting

[@KeithBarker]

Thank you Samuel Darenskiy!

[@wolfferoni]

I've gotta say, I've been studying IT for a while and networking has always been a little dry and confusing to me, until now. I love your enthusiasm and the way you explain concepts. It encourages me to learn more. Thank you for making these videos, I look forward to watching more.

[@KeithBarker]

Great to hear!

[@njj9112]

This is the easiest way to understand IP address I've ever seen! Thank you so much.

[@KeithBarker]

Glad it helped!

[@TheBeach5563]

Thanks for sharing. I really needed this. I work as Network Admin and this really helps getting the basics down in a fun but effective way.

[@KeithBarker]

You're very welcome!

[@DWDM-101]

Best ever explanation for IPV4 addressing. Thank you so much, Keith. Greeting from Myanmar. Your videos help me a lot to learn networking.

Great explanation. I took a fast paced A+ and Network + Class. About weeks each and this reinforced and made clear so much

[@KeithBarker]

Glad it helped!

[@Don-Carillo]

Thanks Keith. Another fantastic watch. You make it so simple to understand. Especially the subnetting using your fingers that i have seen you do

[@KeithBarker]

Thank you Lazerus!

[@kurtisharing8559]

I absolutely love your videos and your CBT Nuggets courses. You've simplified many concepts for me and given me a better understanding of the topics. Please keep up the awesome work...and thank you!!

[@KeithBarker]

Thank you Kurtis! Much appreciated, and happy you are here.

[@khalifakhalifi2397]

Oh dude! I love your CCNA Labs and how you explain things, definitely learnt more with your videos than with my teacher :D My field is more sys admin related, but needs obviously networking skills. You basically have been a very important part of my learning path! Thank you!

[@KeithBarker]

Happy to help!

[@deepaknarayan3713]

So psyched to see you after so many many years. Big fan btw!

[@KeithBarker]

Thank you Deepak! Glad you are here.

[@RonBuning]

Great introduction to addressing Keith! I luv the use of the rulers and slider. Made things very clear!

[@KeithBarker]

Glad it was helpful!

[@jakubmiek1082]

I think it's the best explanation I ever seen

[@KeithBarker]

Thank you Jakub Miłek!

[@gareginasatryan6761]

I teach networking to my friend. The main hurdle is that simple questions have very complicated answers. In other words, you have to dig deep to understand networking. It’s narrow focused and many ITs get bored quickly learning dry conceptual stuff. For example he was asking how to locate a DHCP server on the LAN. I had to go into layers, broadcast domains, encapsulation, subnetting. Just to explain that.

[@KeithBarker]

Thanks for sharing!

[@akliluabay95]

thank you Keith Parker I have got 15 playlist of ccna 200 - 301 , will cover till Saturday class .

Thank you Mark

[@ardentdfender4116]

Watching your IPv6-03 Series videos from way back as a supplement to the CBTN CCNA 200-301 to understand the IPv6 section better as I was confused there. Since the comments are off on that video no where to comment. It was a long video, but really really enjoyed you breaking things down to all it’s very nuts and bolts in understanding. A lot I now understood. In the new CBTN CCNA Course at video 145 I think for IPv6 it introduces lots of concepts and I just could not understand as to me I didn’t get the nuts and bolts to understand all these types of addresses for IPv6. Anyway 3/9 videos in they are solid platinum and really helped. But after watching one very lingering question still remain in my mind: Local Link address vs Global Unicast address. In that I’m still a bit confused as to why a device may need or can have both addresses. If I’m not confused a Router can seemingly have a Global Address and several Local Link addresses on different Fast Ethernet ports. I’m trying to still get that fundamental question answered at to understand why? Assuming I’m not confused. What is the Link Local address doing that the Global Unicast address isn’t doing or vice versa? I do understand I think, that the device IPv6 Link Local address communicates to its local subnet multicast group. I think I’m missing something here. With IPv4 every think has just 1 IP Address and just send packet there. But in IPv6, it appears you can have both a Link Local as well Global Address and I’m trying to differentiate the two.

[@KeithBarker]

Thank you for the question! I have made a note, and when I get to IPv6 here on KZbin, I will make sure to clarify that for you. Does that work for you?

[@ardentdfender4116]

Keith Barker Yes and Thanks. It will be most appropriately helpful answered in the context of the IPv6 video. So looking forward to it. And thanks for having made the various CCNA 200-301 playlist.

[@vectortheartista4801]

great session. I have a question for you sir, do we need programming in networks, because I am a programming student and interested in networks, and plz name some of them to focus on.

[@KeithBarker]

Thank you charaf guerraiche. Feel free to join my Discord sever. Lots of people there helping each other out. Each Saturday at 10am Pacific I hold my "Office Hour" where learners can ask questions about the topics they are studying. Mostly focusing on Cisco CCNA 200-301 topics. Feel free to join us there live if you are available. Here is the link ogit.online/Join_OGIT_on_Discord Thanks again charaf guerraiche!

Glad it helped!

[@thundercatxyz]

How do i find the answer for this question please : You are designing a subnet mask for the 172.19.0.0 network. You want 26 subnets with up to 1700 hosts on each subnet. What subnet mask should you use?

[@KeithBarker]

Thank you for the question Zain. From the Subnet Saturday Playlist, here is how we could solve that: Beginning with 172.19.0.0/16 How many more bits to support 26 subnets. (finger game) Answer, 5 additional subnet bits. New mask is now /21 (16 + 5) How many host bits are left, answer 11 (32 bits total, minus 11 used by the mask) How many hosts supported by 11 bits, (finger game, -2), answer 1024 - 2 = 1022 Final result, there aren't enough bits to go around to create 26 new subnets with 1700 hosts on each subnet. Hope that helps a bit, and enjoy that playlist! ogit.online/subnet
