This was ABSOLUTELY the best explanation of subnetting that I've found. I'm sharing it with my class. This reduced all of the anticipated anxiety from taking the Network+ exam! Just amazing.
So...a class full of subnetting?
@@michaelketchel Networking courses have classes that include subnetting
@@relav6824 twas a classful subnetting joke, sir.
@@michaelketchel oof lol
Your explanation is so good that I literally understood it before you even showed the examples. Thanks much.
This dude kills it with the explanations… great job. I paid for a few courses and I didn’t get it until I watched this. Professor Messer you’re a legend
Man I really appreciate your work! As a student who gets discouraged by long numbers sometimes, your break downs and teachings are so helpful and efficient. Thanks for making hard things appear doable.
I've watched a lot of videos on this topic and this one seems to make the most sense. The process you use and way you explain it is great. Thank you for this content!
I retake my NET + today, I failed once last week with a 669 first try. Have My A+ first try thanks to the PROFESSER, If I fail today I'm buying the NET + BOOK LOL! I will donate when I get paid, this man helps a lot of people for free, God Bless the man.
I just passed with a 723...lol

@@CelluarexpressAny study material besides Professor Messer you recommend to use?
@@Celluarexpress what did it mainly consist of
@jonathancontreras633 Just know what sub Masks belong in which class, also your cable types and speed capacity and distance like 10 base T etc. Also learn about layer 2 and 3 well.
a miracle is underway to happening, thanks Professor Messer!
2:34 BLEW MY MIND !!
I was so lost before this explanation, but you broke it down so easily for me to understand! Thank you
I love these videos. Topics like this are grueling to read via book.
I am amazed at how you came up with a way to unscrew the mind. The books...COMPTIA official stuff and online labs screwed it all up. You have made it right, again! Thank you slow clap!👏👏👏
Thank you for all you do and your videos, thus far, have been very formative and simple to follow!
Similar to another comment but your explanation is by far the best.
Easiest and super detailed explanation! Thank you very much for your great work!
your subnet calculations portion was so easy to understand. thanks!
Professor Messer figured it out the easy and smart way for subnet mask. Thank you!
The amount this stuff clicks is amazing thanks!
best explanation yet.
Best lecture in this course so far
I was stuck scratching my head when i was reading this in my course module. This saved me. No wonder ive heard so may good things about prof messer. I finally understood the concept. And it was a God-send. Thank you!
Thank you for this thorough explanation!
Thank you very much for your help. Everyday I feel more confident that I'll pass the test. Greatings from València, Spain 🥘🥘
I finally understand it! Thanks for such a great explanation.
Thank you for finally making this make sense!!!!
Awesome video. I decided to skip the Networking + certification and jump directly to Security + but after watching these videos have decided to first take the NET+ Cert first. Thank you Prof.
Phenomenal explanation!
Just made everything click for me, thank you so much.
I originally started watching Professor Messer a while back, but switched to another IT teaching site because they had labs as well. Although I will still use their labs I switched back to Professor Messer because the other site didn't explain things well, and took longer to do so. I was struggling with this concept when watching the other videos and he just explained it so well that I understood immediately. Not to mention the other sites videos on Network+ are about 21 hours, and Professor Messer's is only 14 hours so I can get it explained much better with less time spent!
What was the other site with labs? Or if you know good labs for n+ and s+
Literally the GOAT thank you
thank you this has given me great insight on subnet that i needed
Love your videos
Thanks!
Thanks for your support!
What I tried to understand with 2 years of school, this made me understand in 2 minutes 🔥
I finally understand on how to do classful... thx
Amazing finally I got to submitting 😊
I have a quick question. When you are determining the broadcast address for example. You change the host portion to decimal form .255, but on the the network address, you keep it in the original notation. What is the reason to change it to decimal sometimes and not other times? Could you use either form or must some be changed to decimal form?
Fantastic!
I've been taught this 10 times by 11 different people and this is the first time I've been able to understand it........ either I'm dumb or you're great at teaching. Could both be true 0.o
Wow!
So the first host address will be ".1", not ".001"?
You are correct but it is honestly correct both ways.
Guys do you make notes and stuff or you just watch this tutorials/course?
there is a mistake here - class A from 1-126 not 127
A class A address is defined as a first octet starting with binary 0, which means 127 (and the entire loopback range) would technically be a Class A address.
@@professormesser this is compTIA, but other resources have other teaching about this.
@@amjadjadallah96 the definition of IP classes is based on the binary representation of the first octet. CompTIA doesn’t determine these numbers.
