I am due to start a Cloud Engineer role after 20 months on a support desk, and I need to thank you; you have no idea how much your videos have helped.
@NetworkChuck, I have been watching your tutorials for Python and I'm already pacing ahead thanks to you!
However could you please continue the python series? It would be really helpful
@NetworkChuck I need to get DoD IAT II cert which would be the easiest to get I was thinking Cysa but not sure if CCNA Security or Security + would be better?
sir is Osintgram is still working??
i am new bee in it so want to confirm it
Help i if u can leak this man he literaly broke most thing in me pc and he clamis his hack bypasses virtual machines help me and expose him
I randomly stumbled across this channel when i had an exam about Linux commands ( basically I watched one video and I got the full mark ) and every video I watch makes me love IT more and more. I just wanna thank you for your amazing videos bro, I don't officially suck at subnetting ( or anything IT) anymore.
Now I suck even more at subnetting. Will it ever end?
@NetworkChuck thanks for all you do man. I love your videos. Huge favor to ask.... On monday 8/7/23 I'll be admitted into an inpatient rehabilitation hospital to detox from alcohol, after 20 years. Please pray for me and my family. P.S. there's RUclips in my hospital room 😎
Just had to stop by to say I purchased the Boson CCNA labs and curriculum and it's amazing stuff. The labs really take my understanding and comprehension to a whole new level. 3 days in and I'm configuring routers and switches like a networking boss.
Thanks for all your material, recommending Boson, and all you do for us IT professionals aspiring to be better every day.
Facts! Speed up my learning and understanding by light years
how did it go? have you taken the exams yet?
@@JohnSimms-cf9vt I did. Passed with plenty of wiggle room. Just like everyone has said, the Boson practice exams were a bit harder than the real deal. I feel like i was very well prepared. I used a lot of RUclips resources as well though, my favorites being Kevin Wallace and Keith Barker. If you're preparing to take it, best of luck!
This video has been such an eye-opener for me. Subnetting makes so much more sense now, thanks!
Can't thank you enough for these videos. You are very good at explaining and teaching stuff, I finally understand things that weren't very clear before thanks to you
Finally a video from you after so long related to CCNA... ❤
Weird enough this is exactly what I needed
The universe provides
I've been struggling with this whole part of subnetting for months and this video FINALLY made it click for me! THANK YOU
reverse subnetting only works, if you ASSume the person that created the network, followed best practices... or followed any common practices. If they used their vast training in Windows, to create an IP network, your exercise in logic might be foiled!
Love your work explaining ideas, and giving a "theory" base along with them!
Do you have any examples when when and where this would be the case?
spent the last week trying to understand this topic and your video helped alot
Thank you, NetworkChuck, for another great episode on networking.
Watched 8 episodes so far, and learned way more than $50 worth of information. It’s only fair that I purchased more than $50 worth of NetworkChuck coffee… Default Route, 200 OK, and On-call. Thanks for the excellent videos! 👍
This video was the most helpful for me in making things click. Really appreciate you taking the time!
I already knew this but I loved the delivery. Awesome job! 🎉❤
Very nice video! Quickly identifying subnetting issues is a key aspect of solving network problems.
Nice one. Good to see this sort of thing. I'd say most use the class C networks, so good on you for making people think outside the box.
I just started this series and it’s great
after watching the previeos vids, this was the video that made me go "AAAHHHH, now i get it" out loud. Thank you so much
You had me worried for a minute with reverse subnetting then when I watch the video I realized I did this in class. I actually created my own subnet calculator with Excel.
Lol, I did the same thing with Excel when I was learning subnetting. I just plugged Beatrice's info into my calculator and immediately saw the router was on a different network.
Excel... I didn't even think of that, so obvious, its genius @@DP83183
Micheal with the W for team Jesus. Way to go brother! And thank up Chuck!!!
Amazing video like every time ! 🔥
Lovely subnetting skills dear chuck. 😊
This is a great topic that EVERYONE should know (IMO).
It took me a little while, while working at my networking job, to get it down pat. But once you get it... You got it!!
👍👍 Thanks for teaching this to ppl👌
Omggg chuck is uploading so quickkkkk
Love you Networkchuck❤
Thanks for the refresher!
As i began to follow you and watch your great tutorials made with huge passion and love i felt like: he's different, he's a born trainer that spreads his knowledge and experience. He don't make it only for the money (like others). Glad to find that channel. But.. today i stumbled on a video that i like to watch.. Stop, wait what? Only for paid subscribers? That was really disappointing.. is the Coffee Business not going so well.. (?) Hope that the "good" content don't must be "paid" in future. All the best Bro ☕️😉
Well, he's gotta feed his family
Thank you Chuck!!! 😊
This cooked me in my assessment last semester, luckily I got it on end of semester exam😂😂
never failed to educate me 🙏🙏
npc alert
I need your help mastering this. I'm going to give it my all. But I have a hard time learning without some kind of practice. I want to thank you before hand. Your videos are awesome sir. I'm just have a little harder time learning online.
Love your videos bro. Keep it up
Chuck is BACK with some Coffee ♥️♥️♥️ 1:28
reverse subnetting, aka supernetting
subnetting, building small networks from a big address range (i.e. /8 or /16 networks)
supernetting, combining 2 or more smaller networks to a big one
That's how learned it back in the days. Yes, you guessed it, I'm that old... 😂
Amazing! Thank you!
You're videos are incredible and it is so fun to learn from you. That exam question was so fun to work out and understand the reasoning behind it all. I was so happy to see I got it right after watching your videos. Thank you!
I figured it out while on the train ride. Proud of myself
This is a life saver. Thanks❤
Love your content
amazingly explained.!!
Thanks for the instructional video. I dont understand it still but may take some time of getting used. However, that Team Jesus shirt Michael was wearing is amazing!!
Dude I'll be honest, you're more entertaining and educational and quicker, than my college
College is becoming irrelevant
@@stevencorridori3406 the only thing I liked about mine, Devry, it's enrolment every 8 weeks online, 2 classes at a time is full time .-. but you get access to another site with a TONNN of free certifications '...'
You can learn it all 100% free without the certs or degree, but a very blurry road map to follow to correctly learn it all
I'd only advise college if someone needs details they can't find elsewhere
Hey Chuck, fantastic video, man! I'm thrilled to learn new things as an enthusiast. Is there any chance you could make a video about Windows Thunderbolt 4 networking? There's a scarcity of material on this topic, and the existing content isn't very comprehensive. Have a fantastic weekend! :)
I like the content and one day i wanna be like you Chuck
I whish i Had this Video 2 years ago when i installed mi Firewall with subnets and all stuff, realy good Form beginning or AS reminder 👍
You can shortcut this a bit if you're if octet notation by subtracting the first non-255 octet from 256 to get the network size.
256-240=16
So the subnets are 16.256 in size, ranging from 0.0-15.255, 16.0-31.255, etc.
Thank you
Excellent👍🏻
I work in networking and I learn more from these videos than our company kb
Thanks 😊😊
I just spent some time trying to explain some of this to someone else this week.... the problem, I didn't fully understand how to rebuild it in reverse,I just knew that with the /16 they were using, the hosts were too far apart to see each other. I'm likely going to send him this video.
Great video.
Featuring Michael was a great idea.
@NetworkChuck you should cover on how to DIY a Bash Bunny!
Coffee from Nicaragua 😂 it's kind of his favorite!
Anxious to see if you're going to finish the free CCNA series. It'd be a shame if you left it at this...
We need to get network chuck coffee in the UK
God bless you ❤❤
I just started studying this subject. You explain this 10000x easier than my teacher. I just looked at what my teacher published, and I can't understand his learning approach. Thank you so much! You made this easy.
could you make a video to investigate network loop?
Can you please make a video about XSS ?
@NetworkChuck I need to get DoD IAT II cert which would be the easiest to get I was thinking Cysa but not sure if CCNA Security or Security + would be better
I am want re-enter the world of IT; however, despite my best efforts, I have encountered difficulties in securing a job opportunity. My previous experience as an IT Support Engineer I with Amazon spans a commendable 5-year tenure. Currently, I find myself wondering whether it's a matter of my resume or if there's something else wrong, as I have not been able to secure an interview or receive any offers from employers. I continuing to refine my approach and resume, look for that opportunity to contribute my skills and expertise once again.
Thanks for video and you will continue python course ?
hey do you think getting all and any certs from cisco is worth it ? I am studying via ciscos skills for all currently
I still don't get what subnetting is *for* (watched the other videos, and i guess it's to save ip addresses?) or why it would be important to have a human determine them but I'm still glad i got here
Hello. At 4:51 you jump from 32.0 to 64.0 should there not be some 48 in between ? (if increment is 16... ?) (confusing)
Yes, you are correct. Chuck made an error.
We need aircrack and hydra tutorials, Chuck.
would you please make a videos on the topics of starting a cyber security companyt
Hey charles, do you know what is happening in India in the Manipur case
already have had to do this sort of issue in the real world... incorrect IP ranges are common when someone programs the address wrong... it's always good to double check and even triple check... before it hits the support tech...
Have 0 IT knowledge, just stumbled and wanna learn about this but im lost on this episode honestly. Might need to rewatch / take some time but idk. Not adding up just on this last episode. Otherwise chuck makes it very easy to follow along (and fun too)
What's the problem brother. Maybe google IP subnet calculator and pop in the IP addresses chuck talks about. It will break down possible networks, network addresses and broadcast addresses. It might help you understand.
Hey chuck im switch over from Mac to pc for some swe stuff and ML, what’s your setup ?
U the man
Can you make video for bug boundary sir
Hi chuck love from India, I'm 21 and I want to become a cybersecurity professional can you please make a proper series of cybersecurity videos from the beginning to a pro-level so that we can consume information in a more understandable form and become cybersecurity professionals.
waiting for your response
thankyou
Parshiv❤❤
Finding network address is very simple, just do bitwise AND of IP and MASK
Hey @NetworkChuck I been watching your subnetting videos, now I finally know what the subnet mask is for! ... now this may be an idea for a follow up video, but how do you physically implement this? can it be done with a home router? I mainly want to fix my network, isolate iot, but also be able to see it from the main network and I have a few spare routers. I also seen your videos explaining vlans, but unfortunatly my router does not support it and since I live in Argentina, routers that do support it are to expensive for a home network. (Btw I tried using the guest network but the problem is, if that for some devices they need to see each other, otherwise the latency is noticable if they do so over the internet, and if I allow intranet access this means security is gone).
Thanks!
The problem is that it varies greatly depending on the router you have. Typical home routers are somewhat limited when it comes to advanced networking features. They may have some of the features, but their implementation may be limited or not very good. See if you can install a 3rd party firmware like DD-WRT or Tomato or similar. That will let you have much more functionality compared to the stock firmware. These projects have many different brands and models they support, so chances are somewhat decent that your router will work. However, doing this does come with an inherent risk of damaging the router if the flashing goes wrong.
Its impossible to give an exact guide that works for every single router in the world, because as I said, different manufacturers do things differently. Some routers may not support most of these features.
Gotta love reverse Nosferatwo
@NetworkChuck, pls can you make a video of Keylogger I really wanna know how it works.
you should do more linux videos, would be great
nice
nice ❤🤟
I did it in my mind in 10 seconds.
Is it worth to invest time in learning Wireshark by anyone who is not network/security engineer or pentester?
Hi Chuck
Make a video on cameradar or rtspbrute in Google cloud shell
Can you make video about flipper zero or creating it please
I now it old, but in the HTB academy, which linux i need to use? Can I use in Virtual fanbox? Where I install? ubuntu?
Subnetting!! Everyone's favorite topic. 😂😂
Where did the binary code come from?
Is it /20?
bro can u make video on burp suite ?
how do we fix Beatrice problem accessing internet?
I won't remember how to do this... But I will remember this video exists when I need to... Lol
I have a question, lets say our network is 10.0.0.1. And I go through the steps of subnetting and what if had to make more networks but the final number went beyond 255, would we just change it to 10.0.1.1 and continue the same pattern of increasing?
If you spend more money on coffee then IT Security. You're going to be hacked. Joking. I just watched a video on subnetting is amazing. If I get it's got to be good. I just watched someone else's video on subletting and I didn’t get it wven though I've watch yours and you make it fun and ezy. Thank you
Didn't watch the whole video, but skipped to 7:36 to make sure we got the same answers. We did.
5:10 - Me, who works at a Chain of Casinos, yes we do lol.
