[@dwsg1990]

Just wanted to thank you dude!!! I dable in your videos quite a bit and at 33 you gave me the confidence to just in to and IT role after years of trying to slide in to one in a law firm I worked for. I made the jump and am loving it, I applied for the lowest role with a level 3 apprenticeship at a service desk company and at the interview I was told I would be bored with my current knowledge at level 3 they took me on as a second line engineer and put me in for a level 4 network engineer apprenticeship and I love it!!!

[@bonafidesa]

Well I hope I stay as excited as you are about networking. Just put in my two weeks notice at my factory automation job and took an offer for tier 2 IT support at a hospital. Wish me luck and thanks for the push. 👍 No more walking factory floors for 12 hours overnight for this guy.

@@herdenq thank you sir!

[@Fly-Co2]

Hope you are doing well I'm waiting for a final response for my first it helpdesk job

[@bonafidesa]

@@Fly-Co2 so far it's going well. I'm enjoying the team and the work. Hope you hear good news soon!

[@Hightech1811]

Just started my bachelor's degree in IT, been at my factory job for over 5 years, so ready for a change! Congratulations!

[@bonafidesa]

@@Hightech1811 I would highly recommend trying to get into a help desk job now while you learn. A lot of them are work from home positions anymore and not only would you have a foot hold in the industry, you can start to get real world experience in it. Chuck actually did a video on it too. Best of luck and thank you!

[@saminusprime2746]

For years I HATED subnetting. I was always confused as to what formula to use, what the instructor was referring to, kept on mixing up between networks and hosts, etc. But thanks to your easy to follow method as well as your clear & concise delivery, I no longer suck at subnetting (at least I think I still suck, but I did learn a lot from your videos lol). Thank you so much Chuck! I'm not prepping up for the CCNA (yet), but these videos have been very helpful!:)

[@jasonlee0290]

Haha how convenient that Chuck came out with a VLSM subnetting video. I was just re-learning and perfecting this literally just yesterday. Now applying it to lab practices and I already feel like a pro! 😁

[@lord-ks7yp]

Hi. I don't usually comment under videos but I want to say that thanks to you I now have CCNA introduction and CCNA switching and routing certificates. Thank you so much for helping me understand the basics with your videos.

[@toxicity657]

Thank you Chuck for teaching me subnetting in the most intresting way possible , I usually stops halfway through almost every course or literature or series but you Impress me ,you are very good but I must say you have Max Level in Teaching. Thanks I will go to your other series

[@pesfreak18]

Finally I don´t suck at subnetting anymore. Thanks Chuck for the good work. Will watch the series from time to time so I don´t forget what I´ve learned.

[@tawanhua]

I always like to come back to your videos to refresh myself on what I've learned from uni. I took computer network as my domain during my undergrad degree as a software engineer and enjoyed learning the layers of TCP/IP protocol stack. Though, I did find the networking lab course to be the most infuriating course, creating a network and configuring routers, using different routing protocols, configure ubuntu servers, and such that I can't remember on top of my head. If I ever feel like my Software engineer career isn't going well for me I might shift to doing something network IT related like cybersecurity.

[@N1ghtSh0t]

Hi chuck i wanted to tell you you opend my mind to so many things u inspired me now im heading in dierection to it.I wanted to say thank you for your content i learned many things about network etc. Ive watched u since i was 13 now im 17 i appreciate all ur content. ❤

[@eltreum1]

A very important skill. Not just for planning out your service networks but also for understanding and optimizing firewall security policies, sdn flows, acl's, and routing protocols so your network traffic is always fast and reliable.

[@devarshparmar7601]

One of the most interesting things as a network/cyber sec enthusiast , subnetting is so much fun

[@korndogz69]

I'm a network engineer, but I left IT years ago. I used to know the subnetting formula by heart. However, if you don't, you can always just use a subnet calculator. That's been a thing since the mid-90s. Network segmentation isn't a difficult thing as long as you know its purpose, the logic behind it, and that there are calculators to work out the segments if you don't want to memorize the formula.

[@egokenny]

CCNA disagrees

[@korndogz69]

@@egokenny Of course you're expected to know the formula for CCNA and CCNE :P

[@egokenny]

@@korndogz69 did you ever get your CCNA how did you transition into that role?

[@korndogz69]

@@egokenny I actually never got my CCNA, or CCNE. I started (at a corporate level) doing phone support in 1995. After 2 years of that, I moved on to be a field tech. That's where the fun began. I was working with a LOT of different systems, hardware, and software. I was doing break-fix, server/network design/configuration. In between that, I obtained 68 certifications like A+ and Net+ as well as various hardware. I was configuring Cisco routers and switches in a corporate environment, and I just learned as I worked. I had my own network at home that included a Windows server, 5 PCs, and one networked laser printer. That was basically my home lab where I studied new tech. In 2000, I founded an IT firm that provided the same kinds of services I'd been providing in the field. After 9/11 though, everyone zipped up their wallets even for critical IT infrastructure. I had to decide whether to try to ride it out, and take out loans to do so, or close shop at a profit. In 2002, I opted to close, and I went to college during that time just to have something to do while everything settled down. I got my Computer Science: Networking degree, and I assisted in teaching all of the IT based curriculum. It was pretty fun. If I had needed a CCNA/CCNE to advance in my career, I would have done it, but in my particular situation, I just didn't need it. Sorry for the long answer, but I thought it was all relevant to the question.

[@courtblablabla]

I have been trying to understand this for weeks and in the time i watched your series i feel confident enough to do my cisco exam next week - phew what a relief!! thank you so much, subscriber for life dude

[@busus3]

Thanks to you I learned this new skill, there is still a lot of things I don’t understand about networks, but for now I’m confident in my subnetting abilities!

[@gurutheguru]

with the previous videos this is easy. in the end i came to this network ranges and host numbers: 172.21.42.0 - 172.21.42.15 (14 hosts) ... .16 - ... .31(14 hosts as well, i will skip the 3 first parts now) .32 - .63 (30 hosts) .64 - .127 (62 hosts) .128 - .255 (126 hosts) thank you for this course, you made it easy to understand

[@Jorune00]

Hi Network Chuck - been watching you for a year now. Thanks for all the great content! The answer in your video to the Boson ExSim CCNA exam practice question is A. Boson is a great resource for those looking to learn CCNA/CCNP!

thank god ... got A as an answer .... i no longer suck at subnetting

[@skoolit0n406]

Thank you so much for this series, Chuck. Somehow, you made subnetting make sense to me. It is such a weird and confusing topic when approaching it for the first time, but the way you explained it made this complex thing feel really easy to learn. That goes to show how good of a teacher you are. Again, thank you for helping me not suck at subnetting. Cheers!

[@Haufpunk]

Dude, really need to commend your enthusiasm in these videos. Always makes them more enjoyable.

I learnt so much with this series! Are you planning to do IPv6 as well?

[@Cyber_Viking_TX]

Greetings and a victorious Labor Day to all! As the sun rises over the binary horizons, I embark upon the digital seas in pursuit of treasures for my valiant CyberPatriot warriors. Amidst this quest, a video on the elusive art of subnetting crossed my path. In my role as a seasoned subnetting sage, I couldn't resist delving into your masterful explanation. Your prowess in elucidating this complex subject is commendable, and I hereby decree that my audacious Cisco-bound comrades shall partake in this series as an invaluable supplement to their training. Kudos to you, noble instructor! -Cyber Viking

I used to be sucks in calculating IPv4 network, got bad mark in Computer Networking subject. But, i found "magic trick" on web precisely like you did, especially for Class C /24, with help by fingers. Now CIDR or even VLSM seems relatively easy. Ofc, your video today is like some refreshing my memory.

JUST WOW!!! I really appreciate your Subnetting videos...! It was really helpfully

[@christwigger]

Randomly found this video and decided to test myself as I haven't done any subnetting in about 10 years. It's safe to say I can still do it in my head.

[@عباسفاضلملا]

Is this course considered an introduction or a complete one to pass the Cisco exam ?

[@Sayuiv]

Thank you, CHUCK! I was not only sucking at subnetting, but I was also utterly ignorant in the understanding of the subnet mask and /24 meaning. Thanks to you, I solved the exercise (but I did them in order, guest, robots, servers, workers), but I reached the same end of the network, and the process was the same. I literally binge-watched the whole series. I can now confidently say that I do not suck at subnetting anymore! I have a couple of questions for you: 1 Regarding the Bosom question, I reach the conclusion that the correct answer is A 2 I plan to build my home lab, starting with a firewall with PFSense and a managed switch that should allow me to create VLANs. Are VLANs and subnetting related? Thank you again!

[@MeZzZzZzZzZzZzZzZzZ]

Thank you Chuck. These are so helpful

[@scottspa74]

I saw the size/host requirements, stopped the video, and subnetted it in about 5 seconds. Not saying this to brag or something, just saying to preface the statement 'i love subnetting'. It really is possibly the most straightforward thing ive found when studying the 200-301 content. I hope i can lean on that in future job searches (i know that a lot of students i went thru the course with really ztruggled with subnetting - so im hoping my proficiency with it will give me at least some leg up, that said, SNMP and MIBs, and some other stuff just absolutely confounds me). 😖😞

How about next in series similar to this but budgeting networks say you hypothetically get put in charge of a /8 and you have to organize this with mind to future needs. So far you always filled up the available ranges (mostly) now leave some large gaps for future expansion

[@dreamsneezer8668]

Go straight to the interesting octet, find the increment value, network number will always be even broadcast will always be odd and useable addresses are in between.

You'll need to learn how to setup routers and switches. There are many different brands and models all with their own syntax and configuration. Once you understand how to configure a Cisco router for instance, you can setup your own network with various subnets and VLANs.

Great video as always, although I am not sure the conversion to binary is really needed by most people once you get to this level of complexity. Knowing your powers of 2 is all that is needed, and a simple subtract from 32 to get the mask. I also don't see the point in going from largest to smallest.
