As a retired educator, historian, electronics technician, TV studio technician, blah, blah, blah, I have taught many students both in analog as well as digital. So, that gives me a little authority to throw some criticism your way, BUT, there is no criticism to throw your way. Seriously, you have developed an outstanding method of teaching a very difficult concept as we all have found out. Great job!!
Wow… after reading from a lots of articles and youtube references… Your explanation and calculation makes a lot of sense and easy to ‘logically’ understand… Thanks Dan.
By far the best tutorial and I have watched a professor messer and others and they were not as half as easy explained. This is 10/10 highly recommended. Bravo buddy
I am an electronics tech in the canadian military.I am in the middle of my data comms course, and was lost on subnetting and routes, but your videos saved me!
I watched this video last semester while taking an Intro to Network Administration class. A big chunk of the class dropped after the first test because they were so confused by subnetting. Now I had a decent understanding of the concept, enough to pass the exam, but after seeing your magic number explanation I breezed trough subnetting like a boss. In fact, I spoke with a classmate who's taking the CCNA 2 class at the moment and I asked him what the most difficult part was for him; the answer, subnetting. I took out a sheet of paper and showed him what you say in the video and it was like a light bulb came on. He had been under the impression that you had to just memorize all the different sizes and host/broadcast address.
u came here to learn or point out mistakes(for who r commenting)...sir i am a beginner in ccna classes in india and your making it very easy for me.i spend too much time in subnetting but ur brilliant...thank u
Hey man, i really feel the need to thank you, i watch one vid from you and i understand faster then what my professor could teach me in three god damn hours. You are a saint!
URLs Lazic dude I'm in college right now and I got a professor who has the knowledge but his English is very poor. this video help me a lot to subnet easy.
I did CCNA but subnetting class i missed which i got disappointed, u explained well and iwatched so many videos but i didnt understood it proberly. Thanks well dude now i am familiar with subnetting.
wow. weeks of staring at the numbers laid out on paper, I didn't realise it was ANDING with the line underneath, I've been writing it all side by side and wondering how people decide what's true and what's false, I thought you all had some fundamental knowledge I've somehow missed my whole career. Thanks! Probably not my first comment on this vid, I'm learning a lot from it.
Wth man, you really tricked my mind into learning this quickly lol. I guess it's true when everyone says to watch different instructors. Thank you good sir. 👍🏼
@ybrody You are welcome. A supernet if similar to a summary route. Search for summary routes and you will find a few videos that I have posted. You can also check in my CCNA 1and 2 playlists.
I've been searching on CZcams for hours and your video is the closet to answering my question, but it doesn't quite answer it. How are you getting 240 at the end of the subnet mask for /28?
Ok, finally a clear start in binary counting. So you need the 128 - 1 table as a guide for that... AND then its all about counting the inside of the buckets .
The easiest wording for inexperienced "Anding" is for the output to be 1 all inputs must be 1. ANY 0's outputs a 0. (True=1 // False=0) . Just keep in mind 255 in the SNM, means that octet doesn't change after ANDing
+Tinker Bot I have my paper and pen out and noticed the same thing!!! I thought i was losing my mind as this is my 2nd video ever on subnetting :) Thanks for pointing it out too! It's easy to mistake with so many 0's.
Tinker Bot get a book. These videos are for people who already know things from reading books, you cannot learn something from scratch off youtube unless you have read a great amount of books on any said subject.
Excellent video. Easy to follow. Please explain the number "255". How did you arrive at that number. I listened to your video over again, and still didn't hear the explanation. Thanks
255 is from the binary conversion and is the highest possible number in an octet. Seeing 255 means that when converted to binary, every digit in the octet is "on" or "all 1's". There are 8 digits in each octet divided into "places" but instead of tens, hundreds, thousands, etc that you know from the Base 10 numbering system that most of the world uses for everything, the places for subnetting are "128 192 224 240 248 252 254 255". Also 128+64+32+16+8+4+2+1 = 255. Writing these 2 sets of numbers on top of each other can be a good "formula/cheat sheet" to write at the top of every scratch paper that you use for IPv4 subnetting. This video isn't very clear and doesn't get into that so I don't want to get too off topic, but if you want to learn subnetting or anything with networking in general, I would suggest watching Keith Barker's videos or subscribing to CBT Nuggets to get the best ones.
great tutorial.. all the while i was trying to figure out /28 and books explained so confusing when all they had to say was its the number of "1"s in binary lol! only down side of ur video is the sound and video dont sync... sound is delayed
Hi can you do a tutorial on valid ip range and calculating blocksize hats down to your tutorial...Doesn't an IP with the bits of 24 have a block size?? and y? Regards
Because of Dancourses, I can understand subnetting very clearly and other hard configurations. I just passed my ccna today, a big Thank you to Dan!!

Great job!!
Yes, Love your courses. I have never seen anyone explain subnetting so clearly. I love all your courses. Great job!! Keep'em coming!!
True!!
Funfact:I have never seen anyone explaining while using Internet Explorer! LoL
Your courses are great. Clearly explained, well documented and you really helped take out the cobwebs on this topic. PROPS to you, and thanks.

Well done sir. Easy way to understand Subnetting as well as CCNA. Big respect for you!

This guy must be awarded for explain subnetting. never seen a tutorial like this. thanks a lot dear.
Great video to refresh my subnetting before my lab exam on monday, thank you!

14 years ago, and I just found this! ❤ I finally understand how subnitting works.

I cannot believe it. Now I understand numbers in bit notation! Thank you!
Hi, thanks for the time to make this video. It is interesting to know what do the router actually uses the values for.
Best explanation out there. Thank you Sir.👍
Thank you!!!!!! Most simplified way I've seen !!!!!!!
Wth man, you really tricked my mind into learning this quickly lol. I guess it's true when everyone says to watch different instructors. Thank you good sir. 👍🏼
Thank you it makes sense when you explain it!
entire Lecture series is awesome and thanks for Great teaching networking
siddhesh jadhav Thank you Siddhesh!
respected sir , I really found all your video worth and now i successfully solve subnetting problem. Thanks ones again
Great tutorial and very helpful. Thank you.
Excellent video. Very well explained.....it really helped me how to find the network IP address the router has to connect to.
A great way to start CCNA course. Thank you. :D
Its 2022 and im so thankful for this video, thank you so much for helping even though 13 years have passed.
your video rocks! helped me out when i had no clue
You sir, are frickin' brilliant.
dan, you are doing a good job!
thank you Dan, you have the best videos for subnetting; and your packet tracer videos are effective also. Dan for President!!!!!!!
Alfred Caver Many thanks Alfred!
Your videos are just awesome
the best video.. this is the fundamental for anything in administration.. once this is mastered, then anything looks easy.

excellent, finally some real information. thanks.
Good clear explanations !!
that was really helpful !!! thnx a ton fr the tutorial!
Subscribed! thanks Danscourses
Hi,
Am I allowed to include this series in one of my playlists and use it? Or even more, allowed to tanslate it to upload it on my channel?
Thank you! I prefer subnetting with binary! Great video!
Nice video....The voice are clear to understand
Very good video, thanks for the explaination.
so far so good thank you bro
This actually helped a lot
Thank you for making this.
great tutorial! subscribed
I've been searching on CZcams for hours and your video is the closet to answering my question, but it doesn't quite answer it. How are you getting 240 at the end of the subnet mask for /28?
such a nice lesson
11 years later, still learning
Awesome video. I understand now.
This made it all click. Thanks so much
great tutorial Sir
Thank you Dan
Awesome video. Thank you.
GU i a
Newb question, but why does the .55 amount to 0? When subnetting, do you default to the last octet of the subnet mask??
thanks... yes but the point is that you caught it. I was just testing you ... good job. :)
SERIOUSLY MAN? TESTING US? ☺☻ (0)(0)
Do you have another video for class a and b subnetting?
Can the truth table be used with any Class of IP address? This made finding the network ID soooo much easier
Thanks!!! Great help!!!
Hey man! Was this explaining how to get the network address? if not, what was it explaining?
so a like and a subscribe because of a good video more than a decade old.
Very useful and easy
the /24 is called the CIDR notation right? when you add up all the 1s?
correct

is there websites that i could go to practice the subnet things you have taught me ???
plz help
Dan do you have any docs on this method?
Good tutorial man
great video, thanks!
Thank u vry helpful sir,
Nice video but the voice being faster than the video is annoying haha
like the way you explained what was true or false
Thank You So So So much !!!
where do you get the list of numbers that are underlined?
Nonody noticed third octet is lack of 1 bit?
+Tinker Bot all those 1's and 0's as a distractor lol
+Tinker Bot Yeha, it only has 7 ones and should be 8, but same result.
+Tinker Bot I have my paper and pen out and noticed the same thing!!! I thought i was losing my mind as this is my 2nd video ever on subnetting :) Thanks for pointing it out too! It's easy to mistake with so many 0's.

but where did u get the 24? u just wrote 24, so did it appear?

Thanks 😊.
I haven't gotten why at last 24 turns to 28. May you teach me?
This may seem old, but I was curious why the third octet for the IP and Subnet are only 7 bits ? or am I missing something
He just missed a 1, that's all.
@@brierepooc8987 😁 it felt like a thread necro at first but I was like ok he states it but no one else commented. Just covering my bases.
Great ! Thanks a lot
thnk u still helpful
Is the video lagged from the audio?
Nice one.....
AYE MAN ! YOU FORGOT TO ADD A BIT IN THIRD OCTET. NO PROBLEM THOUGH, GOOD TEACHING THANK YOU
@0.57 why did you make 55 a 0 subnet mask? If 55 was 0 then I get it...should be 0 subnet but not sure
thanks
much love
