Berry! We need you to keep teaching the internet how the internet works! I have watched tons of videos on networking concepts, and yours are simply the best! We need you to teach more concepts and more theory so that we can do the same for others!
'You're just learning, don't freak out yet'. Berry, please, make more video's. The way you explain things is so comforting. Wished you were my professor tbh. Your students are so lucky!
I really like the assurance this guy's tone brings. He'll say "Don't freak out yet " That's so reassuring. And that gives me the confidence that I'll still understand it even if I don't get it at that moment and I sure got it after playing the video over again a few more times. Thank you Berry for this amazingly explanatory video.
I recently started taking an online course on Udemy to hopefully get into the vast field of networking. Needless to say I have been overwhelmed by the amount of information thrown at me these last few weeks. I found myself lost and confused so I resorted to youtube for some extra tutoring and I happened upon Berry's wonderfully insightful videos. You've not only simplified things to a degree that they are digestible but you helped me actually learn these things and explained them to a point where I don't feel the need to pull my hair out any longer. I guess what I am saying here is that I am forever thankful for the handful of videos you have provided here. I can't be the only person in the comment section thinking it BUT I will be the one to say it.... BERRY PLEASE POST MORE INSIGHTFUL VIDEOS! Your teaching style is second to none and I would love to see more of your lectures. -A very thankful student
I have been working in IT for over 10 years, obviously not networking, and I have taken a lot of courses that tried to explain this including Google classes. This is absolutely the best course on basic subnetting. You sir are a master instructor.
berry this series on subnetting is exactly what i've been looking for. other youtube tutorials dont care about the why, only the how. you do, keep up the good work
Hi Berry, could you please do more videos on networking concepts as your videos have clarity and would be very helpful for folks like me Who are beginners in networking domain? May I please know if there are any networking articles/blogs that you might have written abdcI could refer to them for learning? Thank you for sharing the videos!
Hi Berry - According to me if one understands subnetting, he probably understands 90% of networking fundamentals, rest 5% are concepts which are based on these basic things. Subnetting can be most confusing which is why I watched hundreds of videos to understand it but the way you explained is simply great. What I instantly liked about your videos were two things, first, your simply language, second, you explain one topic in one video and kept it small and simple, nothing too big and boring. My request to you is plz keep making such useful video on as many topics as you can, especially in the area of network security.
I agree with this, the only piece of constructive criticism I have is that maybe up the quality of the video to 1080p or even just 720p to make it slightly more professional. Other than that Berry, you're doing a great job man, very informative video!
Berry,i really want thank you for this easy important presentation which made me understand the whole concept of subnetting believe me or not it took me years to understand and you made me got it thanks again Berry you doing a great job please bring us some more videos .
You're one of those whom the world is a better place with :). First, a huge thank you for these treasures you're offering for free on youtube, it takes 4 more or less years to understand these things, but with you it takes a video or two... Second, I understand that might be some situations you're having there and it's an effort to make these videos and stuff, so I wish you the best in your life and ofc I hope the world can have more of your treasures around here, but most importantly, Thank you sir for all of this, it's indeed the doing of great masters.
Berry may i just say you have a warm way of explaining this. It makes it so much easier to understand. PLEASE plz plz do videos on CCENT practice questions particularly in sub netting Im s ure you videos would blow up in popularity.
Thank you Berry, you are an amazing teacher. 8:44 @here Does anyone know why in Step 5, he's using 2^n - 2? why not just 2^n ? coz that's how we calculate no. of subnets, what's the significance of 2?
Sir you've made it so much easy. The concepts are rock solid now. The 'Why' is absolutely clear. Absolutely whole credit goes to you! We're waiting for future lessons! You're the best Sir 🔥❤️
Great Video, its good to get a few different perspectives when learning subnetting and this video delivers. I didn't know it was a two-part video so i panicked when it randomly stopped :D
hello Berry Smith, I love your lectures you are an amazing person I can see through your heart even if I dont know you, but I think you are a very kind person, I love your way of talking, it is so formal so clear and brilliant, your heart belongs to one god Only Allah, I advice you to try to make little research bout islam .. Thanks for your effort i have learnt a lot
Mr. Smith, do you have a video, or can you direct me to one, that demonstrates a real world example of how to set up a medium size office network installation; something that will handle 2000 clients? Do you think that vlans would be a better alternative than subnetting? Could compare the two, please? Your videos have really made the mystery of networks MUCH clearer. Maybe after years of fumbling around and not quite understanding what I was doing, I was ready for networking concepts to finally fall in place. At any rate, your videos have been a God send. Thanks so much!!
Hi Berry, your videos are amazing with smart details, .. I Watched most of the videos about the subnetting on the internet in this one of the best. Could you please Sir make a video applying the(subnetting rule) to a bunch of different IPs, as you said it takes more practice, again thank you so much for the great videos and manner.
6:22 with rule #1 it might help to also explain a little more with that, like why it's either an A, B, or C, before moving on, and that's not to say I think you're a bad teacher, it just helps to understand the background of all this
Subtracting 2 from the number of subnets is a thing they stopped doing 15 years ago because they figured out routing devices could work fine with subnets built on all zeros or ones. Consequently, since you can use the subnets of all zeros and all ones, step 6 (finding the least significant bit) reveals the range but does not give your 1st subnet. The first subnet is always the lowest possible address. So, the first subnet in his example here is actually 172.16.0.0 and ends at 172.16.15.255. The LSB (step 6) then gives the 2nd subnet which reveals your range and makes finding the end of your 1st subnet easy with the subtraction of 1 (hence one back from the 16 gives you .15.255).
@@tamasprotovin3731 I spent over a day researching videos before figuring out two discrepancies I was seeing that straightened the whole thing out. This was the simpler of the discrepancies; a simple Google search was all it took after watching tons of videos trying to figure it out.
What's the difference between a VLAN and a subnet? Can you have 2 different VLANS (say VLAN 10 & VLAN 20) in the same IP Class (say 192.168.1.10 /28 for VLAN 10 and 192.168.1.20/28 for VLAN 20)?
Hi Berry, can you please make a video about tcp/ip and osi model? How data communicate inside osi layers and etc.. make some basic networking tutorials. I'm learning this for CEH. I got the cert from attending the official ceh course, but the instructor did not really go onto basic stuffs like that, please if you don't mind :) thx for sharing such information in a way that everybody could understand :) even for me with only-basic knowledge of english vocabs can understand topics you explained.
Great video. My only hangup is in methods for coming up with the initial network id of 172.16.0.0 . It seems that there are rules or guidelines about doing this, or determining the class beforehand, rather than discovering the class from an ip chosen arbitrarily. 172.16.0.0 itself seems to be a regular choice.
Thanks for the response. You're absolutely correct that there are rules and guidelines to follow when it comes to subnetting and IP addressing in general. You're also correct that an administrator would determine the class before they ever began the subnetting process. This class determination would typically be made based upon how many subnets are needed as well as how many IPs are needed per subnet. Obviously a class A network will allow for more IPs than a class B which will allow for more IPs than a class C. The beauty of 172.16.0.0 is that it falls under the private IP umbrella which means an administrator can use it any way they want. No asking permission and no registering the IP with any regulatory body. It is very common for an administrator to use these private IP ranges because of the freedom they bring. For instance, chances are you have a router connected to your ISP connection and in that router is one of the private IP ranges (most likely 192.168.x.x). You can use any private IP range for any purpose (other than directly connecting to the Internet. Private IPs can't directly connect to the Internet). You can also choose to use any private IP for your subnetting needs. I chose 172.16.0.0 for no other reason than it was the one that popped in my head when I started the video. Gotta love them private IPs! Thanks again for the response!
That is beginning to make sense. I also saw that you had covered some of that in another video, so I should have watched in order. Thanks for the very helpful information.
Oh man, how did I miss this comment!? So very sorry. Sadly, that spreadsheet is long gone and went away when I left the school. The only thing that was really on the spreadsheet is what's on the board in the video. The 2^n chart, the binary calculator, and the 6 steps I went over. It was placed in the class as a quick reference when the students were doing subnet practice on their own. Again, so sorry it took this long to respond. I flat out missed this comment.
Your videos need much better production quality, but overall, you're an excellent teacher. Thank you for your assistance, I've given these videos to many of my new coworkers.
First, thank you for the post. So it's funny...I made these videos for an online college I became dept head of never once thinking they would be seen by anyone outside of the school. The classes were just horrible and I felt like the students weren't getting a good education vs. what they were paying. I just felt like I had to do something to help if I could. I took an old camcorder (even old for when this video was made which was about 10 years ago) and just sat it on my desk in my office and hit record. After I left the school I made the videos public as pretty much a joke. I honestly thought a few people might see one or two of the videos and I'd get a fat comment and that's about it. Never in my wildest dreams did I think so many people would take time out of their lives and leave such heartwarming comments on videos that I, some fat dude trying to help crappy classes, made in my tiny office. The reason you see me walk in and out of frame is I'm walking back to my desk to stop the camera. Thanks again for the comment.
