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
Hey! I just wanted to leave a comment saying your video was extremely comprehensible! Your methods like building a chart and mentioning the many ways you can use math to quickly interpret and solve subnetting problems are very helpful! I'm here after taking a coursera Google IT course, and they made a blatant mistake in their video about subnetting that only left me more confused. After multiple other videos where I've been building a grasp of subnetting, this one really helped me to compartmentalize how these numbers are relating to each other and what they *mean.* In addition to all that, I have an auditory processing disorder and it makes it difficult for me to process familiar speech patterns, let alone accents. HOWEVER, I had no issues understanding your accent and I actually found it very comforting, as I had a Chinese immigrant teacher in High School who taught my first programming class. Captions do wonders for those who need assistance with hearing, but you definitely don't need to apologize for the way you speak! I'm thankful you decided to upload this content!
Beautifully explained except one Big Mistake, you've Altered the Definition. Iterative query is between a DNS Client and its local DNS Server. Recursive Query is between Local DNS and Other DNS.

Men... Your the best example of a works smart than work hard person... Thumbs up big time to you men ... I perfectly understand this now I'll try this later... Hopefully I pass my tier 3 exam soon
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.
