What is Subnetting? – Subnetting Mastery – Part 1 of 7

This video will teach you the basics of subnetting. Every Subnetting problem will ask you to solve for one or more of seven possible attributes: Network ID, Broadcast IP, First Host IP, Last Host IP, Next Network, Number of IP Addresses, and CIDR/Subnet Mask conversions. This video explains what each of the attributes are.

What if there were a single video series that could make you a Subnetting Master? What if that video series were available for free, for everyone?

Look no further. This is it. This is video 1 of the series. The complete video series will make you a Subnetting Pro.

    I have had subnetting explained to me a half dozen times and still walked away scratching my head. I felt like such an idiot!! I don't feel like an idiot anymore. Thank you so much for being such an excellent teacher!

    Why isn’t this the number one result when searching subnetting. So concise. Quality Production. I’ve seen videos with ten times the views with crap quality video and audio, confusing, and scrambled that I leave as confused or more than when I started. I literally send this link to everyone that asks for help with Subnetting. Thank you a thousand times over for this.

    why are you initially saying that you can split the /24 in interval of 8 ? can't we use /30 and hence have .0 .4 .8 .12 .16 etc ?

    41 seconds in and I had to stop to read the comments…. WHY IS THE AUDIO SPED UP!?!
    Either it's someone with an accent or someone just going too fast!
    I read the Net+ book and Aced the class.
    I just need the damn Subnetting to click.

    Many students will get confused with /32 bits. careful when you explain that. as you can't have more than /32 bits in a subnet or IP address. In min 3:50, you are splitting 25/, /27, /26 which is reverse should be 78/ and that number doesn't exist. therefore my dislike, I saw 3 of your videos and they are all perfect but this one makes all of them unclear

    is there any way to find the subnetmask and which subnet thats in from just a host ip (only known information is that this host ip is in the first subnet, and that ip is 192.224.1.19)?

    I've got dumb question… why dedicate an entire exam to building these network subnetting maps by hand? It would be pretty easy to build a visualization tool for automatically building these maps internally.

    I should clarify that this video series is really neat, but my first instinct when seeing this is… I want to build a GUI that has these techniques codified, which means… I need to master them by hand, first.

    I can't believe it!!! He is literally explaining and answering every single part of subnetting something that I have been struggling to find and to understand. Thank you very much, coach.
