      Hey Jeremy, start the video at 28:02, within a few seconds you state, "Because the network portion is very long..." It is regarding Class A, so you meant to say, "Because the network portion is very short", "Because the network portion isn't very long", or "Because the host portion is very long."

    One suggestion: since many of the viewers have previous knowledge on some of the subjects, it would be great to split each lesson into chapters and put markers in the description. Thus they could easily skip or review some parts.

    A little trick I'm using to calculate the decimal from the binary is that if the majority of bits are 0 then I add up the 1s columns, but if the majority are 1s then I deduct the 0 columns from 255 or whatever the maximum possible is (if there are 0s on the left side so I deduct from whatever smaller number would be from all 1s up to the last 1) if that makes sense.

    Hey Jeremy, I have just come off a 7-day CCNA bootcamp with Infosec
    I planned on using the course to grow my area of expertise at work and was initially very excited to attent. However, the course did not go as planned and I felt like I was drowning the majority of the time as the majority of it was hands-on with little to no explanation of theory.
    I've worked through the first 7 days of your course over the weekend. Feels like you hit the balance of theory and lab the head, you provide reinforcement along the way, and do it all engagingly and concisely. Looking forward to the rest of the content and thank you dearly for your time and effort on this.
    You have a real gift for teaching, thank you for sharing it with all of us!

    Watching this video as a review after taking the TestOut course for Routing and Switching Pro, I was struggling to memorize the 5 different classes of IP addresses. However, when you put all of the classes in a table using binary to categorize them, it made so much sense!
    Binary has become second nature to me after tons of practice, so remembering which IP address range is in which class has gotten much easier for me after you used that representation.
    Thank you for all you do!

  • @parampreetrai7093

    We can also convert decimal to binary by dividing it by 2 each time and noting the reminder.
    Like 127 to binary
    127 % 2 = 1
    63 % 2 = 1
    31 % 2 = 1
    15 % 2 = 1
    7 % 2 = 1
    3 % 2 = 1
    And last note both reminder and quotient
    1 % 2 = 1
    1 / 2 = 0
    Reading backwards you got answer 01111111.

    something that made me get a AH HA! moment is realizing that the lower the number on the OSI model the closer you are to the source. So physical is the source and the farther you are is how the transmission taking place and what you are doing with said transmission. So Application layer is an app sending out a signal all the way down to the physical layer which is the end device.

    Damn, I was in the garden listening while watering and doing the binary in my head and heard that you didn't have the "1" bit "on" for 221, and thought, 'that' not right'. I came to the comments section, all proud of myself, to point out that for any odd decimal value, the 1 bit must be on, only to find you already pinned it to the first post 😔 (bubble burst). 😄 Thanks for all the great content, though. I got your CCNA course, and am just now checking out the flash cards. Hoping to take CCNA exam soon. 👍🤞 (Also, tip: to solve for 221, subtract 221 from 255 and you get 34, so just disable the 32 bit and the 2 bit - that's how I sometimes approach it) (another example, the decimal 207: just subtract 207 from 255, you get 48, so just disable the 32 and the 16 bit - this method allows you to calculate these in your head in under 2 seconds, usually, without looking at paper or anything. I find it a helpful, quick way to calc binary octets.) Hex, on the other hand, I'm hoping you have some good shorthand for, cuz it always trips me up.

    Thank you Jeremy, I have seen and taken many course but this is most comprehensive and easy to understand course, you are the best instruction. I just want to know how do we determine which is network portion and which is host portion without knowing /8 or /number? Thank you.

      If you don't know the prefix length (written as /8 for example, or in dotted decimal like 255.0.0.0), then you can't know what is the network portion and what is the host portion.

    The easiest way to convert from decimal to binary is to do series of divisions by 2 without reminder :
    221 / 2 [1] (bit 8)
    110 / 2 [0] (bit 7)
    55 / 2 [1] (bit 6)
    27 / 2 [1] (bit 5)
    13 / 2 [1] (bit 4)
    6 [0] (bit 3)
    3 / 2 [1] (bit 2)
    1/ 2 [1] (bit 1)
    We divide the number by two and write 1 when the result is odd and 0 when it is even. The last division gives the first bit.

    16:46 = I believe this may be wrong
    128 + 64 + 0 + 16 + 8 + 4 + 0 + 1 = 221
    But I do like that style of working it out'
    Sorry, I wrote this before I saw your comment above.
    Great lectures though

    I like the quiz on converting binary to decimal and vice versa. I am already familiar with the sums of 128+64+.. for when I'm computing the subnet masks in vlsm, but having different binary patterns worked my mental math skills haha. I only made 1 mistake on #2 because I forgot to add 15 to 112 to get 127 even though 15 was the first thing I computed 😅
