    Thanks Prof. I am actually preparing for CCNA and subnetting was giving me such a hard time. I’ve watched a lot of tutorial but none were as vivid and effective as yours. You are a trully dedicated teacher. Many thanks

    Whoah, that’s quite a chunk of information a relatively short amount of time.
    I must admit that I’m completely lost on the subject at this time.

    But like I said, it’s a lot of information a short amount of time so I hope I’ll get it after I go through it bit by bit a couple of times.

    Excellent Video Tutorial Professor Messer.
    Very accurate and easy to follow.
    I paused occasionally to do the calculations myself and this helped get the jist of it. Thank you very much.

    Thank you so much! I’ve tried learning Network+ in other ways. This is the best I’ve seen/watched so far. Understanding subnetting has never been so easy to understand after this video.
