Subnetting Made Simple

Here is a method that simplifies the process of subnetting. Hopefully it will help you understand what's really happening when networks are divided up and why subnet masks are important.

After about 20 videos and countless hours, I found this...and it makes sense. This is by far the best/easiest example I've found! Thank you!

[@sanmiol]

After 2 days and also countless hours, I found this video. So simple!!

[@danielboudreaux4716]

@@najashitv6460 usually you can find it if you have a slash notation, if it was say /25 the subnet mask would be 255.255.255.128 and /26 would be 255.255.255.192 and so on

[@S24W2]

I thought I was stupid as I was moving from video to video too! I realise now that it's just the way it's explained! What I find confusing us how is the subnet mask determined???

[@1993aneliya]

2.5 years working in IT and couple of Microsoft exams but this is the best way to subnet ever, no cheat sheets no nothing just pure logic, thank you!!!

[@InfiniteTony]

But doesn't borrowing bits matter? I was hoping he would show us how to do that the simple way but nope lol

[@vxbrance8477]

@@InfiniteTony for real, so confusing because the 2 in the 3rd segments in the Network adress only remains in the same casue it cancels each other out if you compare it in binary with the subnetmask. 00000010(IP segment) and if you compare it to 11111111(Subnetmasksegment) it remains 00000010(= 2). Terrible example in my opinion. The other parts were well explained tho.

[@JosephUsher]

I'm in CompTIA Network+ class right now, and we just learned to do subnetting last night, and I can tell you that it took MUCH longer for the instructor to go over it than you just did, and it was MUCH more difficult, not to mention confusing. Thank you for sharing this extremely simple method!

[@hirofumi3123]

9 years later I’m here being so thankful to this video ❤️❤️ I’ve watched like 30 videos explaining this topic but you’ve done it so well and so easily. Thank you so much I need this for my exam 💪💪✨

[@JamesJSwiftJay]

Whenever I need to learn IP subnetting again I come back to this video, to this day this is the most simplistic and easiest way of understanding subnetting. Thank you Carl for sharing your knowledge.

[@lanecurameng]

Carl, Your tutorial is THE ABSOLUTE BEST in this subject--confusing as it is. I'm studying for my CompTIA A+ and subnetting was the only thing keeping me from feeling confident I could pass the exam, let alone finish it! And you put this all together in just 5:40. Thank you so much, Carl! I especially loved the way you did the tutorial using a simple piece of paper and a pencil. It simulated what will actually be the case during an exam.

[@EldenLord00]

That’s hardly in the exam

Carl, I've been trying to figure out subnetting for longer than I'd like to admit. Your video finally made it click for me. I'm so glad you never relied on borrowing bits, just plainly laying out what the binary is telling us. THANK YOU SO MUCH.
