    Thank you Sir.. it amazes me how I can spend the whole day at school being taught something, not understand, then go on YT, watch a few short videos and instantly get it!!

      You're not alone! Have you ever heard of the Khan academy? There's a TED talk about it from a few years ago that I would highly recommend.
      In any case, glad you enjoyed the content. Cheers, Shawn.

    In all honesty, you are a natural teacher, a teacher per excellence. Thank you very much for your direct and really well broken down style of teaching with more than adequate easy to grasp examples and exercises. Thank you!

    You are making networking easy for us, thank you so much.❤ Can you also make a video or article by explaining the TCP protocol in detail, i mean packet by packet analysis? I could rarely see good detailed explanation for TCP-UDP around internet(all i can get is TCP-UDP differences), even in my CCNA course nobody explained me well, but it needs packetwise understanding while we search for jobs. So if you cover the topic it would be great help for us, because you are very good at explaining things especially a dull or dumb student like me. Once again thanks😎👏

    hello sir, how can i combine two devices into a single wildcard mark? i mean i could be given the task where there are two devices that i have to deny the access to servers by using a single rule. thank you for your help

    • @PracticalNetworking
      @PracticalNetworking  2 ปีที่แล้ว

      What you are looking for is what's called Supernetting, or IP Aggregation. I made another video about that here: th-cam.com/video/Q4MArJTbUwk/w-d-xo.html

    I was wondering how I encountered a network with a 255.255.253.0 subnet mask.. I'm fairly certain it was a typo but the network was acting oddly (not connecting to certain devices).
    In binary 11111101 is 253, so it's between /23 and /24. How could that work?

    • @PracticalNetworking
      @PracticalNetworking  4 ปีที่แล้ว

      It could very well be a Discontiguous Wildcard Mask: th-cam.com/video/57ZcCuJ90qQ/w-d-xo.html
      Although, my first inclination would also be that it was a typo. Discontiguous wildcard masks are pretty rare.

    Hi I have a question like when there is 2 network e.g 10.10.2.0/24 and 10.10.3.0/24
    how do I calculate the wildcard mask for 2 of the network together

    • @PracticalNetworking
      @PracticalNetworking  3 ปีที่แล้ว +1

      You could convert both IP addresses to binary, and build a Wildcard Mask where (starting from the left) there is a '0' in every column where the bits are identical. Then when you come across the first column where the bits are different, everything else in your wildcard mask is a '1'.
      Alternatively, the question is mostly just a Subnetting question. In which case I'd direct you to my Subnetting training series:
