Hello, my name is Sunny Sun, Associate Professor of the Cybersecurity Program at the University of Saint Mary (USM), Kansas.
I have been teaching at USM many different computer courses of both Computer Information Systems and Cybersecurity: Web design (HTML, CSS, & PHP), Networking, Ethical hacking, Cryptography, Digital forensics, Database, Data structure & algorithms, and computer programming ( Java, C#, and Python). I enjoy teaching.
I hope these videos are helpful in your study or as you prepare for the national certification tests (CompTIA Network+/Security+, CCENT, or CCAP).
Thank you very much for your support by becoming a Sunny Classroom member. Your support is much appreciated. www.patreon.com/sunnyclassroom

excellent class
this dude is great, thanks
ver nice
THANK YOU!!
Hopefully someone can help me out here even though it's been a few years since this video was up, but how did he get to the number 63 for the Broadcast ID? Many thanks whoever is willing to educate me.
So helpful tanks
Awesome way to subnet. Really simplifies subnetting. ❤ However, I have the same question as @orcnewmymail. What would this table look like with less Network bits? And sacrificing an entire subnet is totally new to me.
Great! New suscriber here....
Its not HTTTPS.
We divide 16384 by 256.. can someone explain why and where the 256 came from ?
I love u
Thank you! This video was pretty helpful. But when it comes to a request like 14.53.233.153/20 i couldnt find a way to use your table. Would you mind to explain?
This is a nice video on cyber kill chain. Some similarities with supply chain management. Hope similar videos will publish more.
Great teaching . Thank you sir :)
Although I see why this method is called Frequency Hopping. I don't see why it's called Spread Spectrum though.
OMG. Liked. Subscribed.
U r agreat teacher
doesn't this only solve for /24?
Hi Sir, what if subnet is less than 24
Awesome explanation. I have a question though. Is there another Sunny Table in case we need more than 256 hosts?
Thanks for connecvting tagging to Trunking!
Thank you
SO FUN!
watching this in 2024. thanks a lot this is very simple and concise!
Just want to say that you're my go-to guy when I need some tech explanation. You make it very easy to understand! A BIGH MAHALO to you Sunny!
Good explanation.
Excellent explanation sir.... Thank you so much ❤❤❤❤
Great job! It was so easy to understand.
thank you Sir
Loving your video
Thank you
Sorry if this is a blonde question but in the real world - who choses what your original ID is? A lot of the case studies I see in textbooks start with "you've been given this network ID with this mask, generate n number of subnets." What I don't understand about all of this is, how does this original network ID get generated for a business or organisation, and how does it get passed down for you to work on? Second question - it looks like there is not a fixed limit for the number of hosts and subnets. The table in the last video stopped at 256, this one stops at 65536. Are there realworld practical limitations on the number of devices a business can include in a subnet? Thank you so much for your videos - you are my first ever KZread subscribe because they are wonderful.
Mr. Sunny, I’ve just made practical CCNA exam only because of you. Many thanks from the Czech Republic! 🙏
You can always count on Sunny to have your back!
This looks cool for class C IP address. Why is no one asking what happens when it's a class A or B IP address!!
This is by far the simplest most intuitive subnetting approach on youtube! Thank you sir!
Thank you Sunny! It takes great intelligence to teach subnetting so clearly and simply.😊
Much Appreciation. I had 3 hours lecture on it but clearly understood from your video.
It would be great if these graphs more clearly indicated what domain they are in!
Can someone explain to me please, why we divide 16,384 by 256, not to some other number? 6.57min on the video.
hallo.
"A diligent student needs no master"
Excellent video
hey please show me how to find valid subnet and valid host
Why is the subnet /27 instead of /24?
got my exam in 2 hours, well hope this covers it, if it's asking /16 address i hope I know what to do
Simple and straight to the point, thank you!
If my router did a PAT from port 80 to 8000, how does the other router know that I'm requesting a port 80(web) instead of 8000? Thank you.
Sunny, great video.
