So in this video I will be showing you an easy way on how to do it so if you're interested, please keep on watching and I hope you learned something from this video.
If you have any questions or video requests, please feel free to comment them down below. THANK YOU!! - Věda a technologie
My mind was malfunctioning in class learning this. But this video redeemed me, thank you.
Awww that's good to hear. You're welcome and goodluck with your classes!
Awesome! your method of teaching makes it very easy to understand, I'll be searching for more of your work.
Thank you so much!! Glad it helped!
nice video very well explained. just one thing, I have doubts about what would be the new mask for each subnet that you created?
Your method is really straightforward and simple, thank you for making this video!
Glad it was helpful!
Great video, very straightforward. Your instructions was easy to follow. I like your use of graphics on the video.
You are a great instructor in addition to your IT credentials. Thank you for all the work you put into your videos. Yes, we notice and appreciate it.
i have no word to express your method of teaching
i tried to know about this concept and now i get all what i wants
darlng sis , keep it up and do more you have good talent !!
You're very welcome!!! I'm so happy that I could help. I really tried to make it as simple as possible with just few steps. Thank you and will keep doing videos!!
Hi! I appreciate your videos, they are super helpful. I’m looking to get into the help desk for role for starters and would be awesome to see a video on common issues you’ve helped user with as an It support! Thanks for the video :)
Hello there!! Thank you!! Goodluck with that!! Oh ok I can make a video for that!!!
@@EastCharmer yes please make a video on the issues you have done earlier for the clients..
Thank you for these videos on subnetting. I'm going for my CCNA soon, and this was a big help.
You're very welcome!!!! I'm glad this could help!! Goodluck on your CCNA exam!!! 🙏🙏
How did you go?
Thank you so much for this very helpful video! I understood VLSM within 10 mins, something my university lecturer could not do !
You're very welcome!! I really tried to simplify it and apply it to real world scenario. Glad it helped!!
thanks for the video i had been confused about VLSM for a long time before I watched this video
You're very welcome! yeah VLSM can be connfusing but it can also be simplified too and applying it to a scenario would make it easier to understand as well
Hi there let me thank you from the bottom of my heart because your video was so clear so well explained and it's been a while that I was trying to understand this subject of VLSM and it was just difficult but with you, I understand with any efforts it goes by itself
And when I think that all these explanations is for free I'm just speechless and thank to you i was able to i see the other video that you made with the other students and it helped me a lot to know what's going on subnetting just infinite thanks
I guess that the best i can do is obviously like subscribe and share but also pray for you may God bless you and i wish you a good health many success and a blessed life.
Peace and love on you ❤
Hello!! Thank you for the nice comment! I'm really glad that our videos are helping a lot of people. I started making IT videos because when I was starting, there were only a few or almost no resources that are free and accessible for me to learn. So I'm happy that my videos are helping out too. Thank you for subscribing and I hope we can make more content! Goodluck on your career as well and if you're taking exams!
I think there's a mistake about the broadcast address. The broadcast address is normaly the last address of a (sub)network, and not the last -1 like you said. That's why a 30 hosts would'nt fit in a CIDR /27 subnetwork according your video.
Uppon this mistake, I found your explanations really good !
that's what I also think, but it's a great explanation
This is awesome…. No one explained this realtime scenario thank you for your time👍👌🙏
You're welcome! Glad it was helpful!
You forgot the mask of each subnet though
Thank you, I found this video realky helpful. God bless you
Thank you alot! In class I didn't understand VLSM at all but your video helped me understand it. I wish you also included subnetmasks but I figured it out eventually. I'm sure to check out your other videos aswell!
You're very welcome!! I really tried to explain in 3 simple steps that is easy to remember. Oh I forgot to include a lot of things like subnet mask and class a and b. I'll try to make another video for that
@@EastCharmer Yes but everything else is easier to figure out when you understood the basics haha. If you decide to make another video I'll be sure to watch it 😄
Take away the amount of device hosts you need from 256. Assuming /24 major network, 30 hosts (remember you need 2 for network and broadcast), 256-32, then the mask is 255.255.255.224. Need 64, you need 2 for network and BC so then the largest subnet you need, which is 128, means 256 -128= 128, so the mask has to be 255.255.255.128. As for working out notation from /24 think how many times do I need to split to get to the subnet size, need 32? 256÷2=128÷2=64÷2=32, I split it 3 times, therefore 24+3=27, so a 224 network is /27 notation.
Wow this is so amazing what intake weeks to understand I got it in a couple of hours thanks great job
glad to hear that this video helped!!! thank you!
Woah. Finally I can understand this hahaha. THANK YOUU🙌
Yaaay!!! You're welcome!!
You will be a great trainer! Thanks for video!
Thank you! I hope I can be like one someday!
Danke
Einfach und verständlich!!
Be blessed i finally understand VLSM now
Thank you! I'm glad this video helped!
Thank you sooo muchhhh! I get this. God bless you!!!
You're welcome!!! I glad the video helped!!
This was awesome, thank you so much for the lecture!
You're welcome!!
Very clear and precise, thanks
You're welcome!!
Thanks! This is helpful. Keep teaching!
that's great! you're welcome! I will keep trying to make tutorials
The video is quite helpful. I would love to see how you apply each available IP address to each host.
What will be the sub netmasks for the networks that you sub netted using the 3 steps ??
Wonderful explanation !! Better than my teacher.
Thank you! Glad you liked the video.
You are writing 8 in what a wonderful way !!😀 But it's very simple method to teach to students. But I am doubt whether it can be used for every possible VLSM subnetting
oh lol I am used to writing it like that. hhmmm it is actually more practical to use VLSM, maybe not on all networks but for WAN links for example, it's helpful not to waste a bunch of address if you only need 2
thanks a lot really helped me to clearly understand the concept of VLSM
🥰🥰🥰
You're very welcome! I'm glad to help!
Very good explanation, but I think you should have added the subnet masks to it and/or the CIDR notations, as they are very important for this to work. I like your videos 👍
I don't see the /cidr notation for each network, that would've been helpful to really understand VLSM.
This was great, thank you!
You're very welcome!
Excellent tutorial! Thanks very much
Thank you glad you liked it. I also have another video on tips on how to answer subnetting questions
@@EastCharmerGreat!! I'll check it out
Thank you very much for this~!
You're very welcome! Glad you liked the video!
hi ! in this method how I know the subnet masks of every ip?
Explained very well.
Thank you so much! Glad you liked the video
Thank you so much!!!
my pleasure!!!
I have my computer networks examen tomorrow, didn’t understand VSML and was super stressed, after seeing this its so simple. Thanks!
yeah it seems overwhelming in the beginning but once you understand the concept, it is quite simple and practical. Just keep practicing and you'll master it
thank you!
you really helped me thank you
You're welcome!!! I'm glad that the video helped!! 😊
very useful, thank you very much
You're very welcome! Glad it was helpful!
Thank you for your help
Happy to help!
hi, i just wanna know, why you stop the hosts and broadcast at .105-.106 and .107? can you explain?
Thank u so much!
You're welcome!
🔥
you're a life saver
appreciate it!
Best understanding for vlsm
Thank you. I'm glad the video helped
holy smokes..not only is she SMART and a GREAT teacher..but she is also super DROP DEAD GORGEOUS!! 😍🥰😍 by the way thanks for the Lesson!!!!!! Def a charmer!! LOLL ::))
thank you for the kind words!!! Glad you liked the lesson and many more to come!
This is also fucking excellent!!! WOW! Thank you! I will NEVER FORGET subnetting.
You're very welcome! Glad this video is helpful.
@@EastCharmer let me firstly apologize for the profanities. But I was truly elated.
You should do Class B and Class A networks using this method. I had to work it out but trust me…..this made it all make sense in an instant. I thank you again!😁🙏
thank u sm !! :)
You're very welcome!!
really good video, thank you
Thanks!! You're welcome!!
Thank you for the help😄
you're very welcome!
i am having exam in 2 hours and watching your video
Goodluck!! I hope you pass!!
Excellent video!
Thank you!! Glad you liked it
thank you so much madame❤
you're very welcome!!
YAY!
Yay!
Great videos!
Thank you! Glad you liked the videos!
thank you so much, this was helpful for better understanding my class
You're very welcome! I'm glad this video helped and I also wanna share how to use it in practice
I never used VLSM in production. I just use /24 everywhere for every VLAN.
well it depends on the admin but at work we typically use /32 for network interfaces coz it will only have two hosts. it's more practical than using /24 and waste all 20 ip address for network interfaces
@@EastCharmer in my case I’m not really wasting anything.
@@Syntaxstic yeah it always depends on the environment you have. we work with developers who constantly needs test VM so we're being practical with our subnetting
Amazing!!
Thank you! Cheers!
can you please do a video on point-to - point configuration
what about the Cidr for the networks?
Thank you so much🥺
You’re welcome 😊
Thank you.
You're welcome!!!
Thank you
you're welcome!
thanx a lot
very useful
You're very welcome!!
thank you for your video. I have a question tho will all the subnet mask still be /24 or they will change
you're very welcome! sorry I should've include the subnet mask too. They will change too and that's depending on the number of hosts like 2 hosts would be /30, 6 hosts /29. /24 is for 254 hosts
thank you very much@@EastCharmer
@@josiahnimfa5134 you're welcome!!
Ohhhhh thankss
Great , just as a recommendation do not block the board at all time please :)
Thanks! Noted!!!!
@@EastCharmer can you do a tutorial of se wan or ansible ???
nice work, thanks
You're welcome!!
What if the host is 139 or something how can we solve it with the chart
Hello Ma'am, I have a question if I have 7 host, what do I use 8 or 16? Thank you for making this video!😊
Hello there! You're welcome and I'm glad you liked the video. Ok so typically, rule of thumb when designing networks is if you have 7 hosts you should go for the number that is more than the number of hosts and can also accommodate the broadcast address within that network. So if you have 7 hosts and then increment that is more than number of hosts is 8, you should still have to consider the 2 broadcast address that you need to reserve and also being able to accommodate more hosts in the future for scalability. So 16 would be ideal if you have 7 hosts.
Hi, what would the subnet mask be for these? I am a little confused
Hey, subnet mask will depend and vary on how you would divide the networks. You would base the subnet mask for each network based on the number of bits being borrowed. For example, for the wan links that only needs 2 hosts, you need to borrow 2 bits and if you would write this in bits it would be 11111111.11111111.11111111.11111100 (the zeroes represents the borrowed bits) . If you count all the bits(ones) in that mask, it will be 30 total hence /30. So for the network that needs 2 hosts, subnet mask would be 255.255.255.252 in decimal form. I know it's not easy to visualize and it's also hard to explain without illustrating it :( but I hope that helps
Thank you sister ❤
🤗 you're welcome!!
thank you
You're very welcome!
Amazing video
Thank you! Glad you liked the video!
Great video on how to create networks of given sizes. And great personality for making videos. I feel like I could listen all day. But if I'm being critical (sorry), why reference classful addressing here? It's use was discontinued over 30 years ago. Am I wrong to say it doesn't have anything in the world to do with creating subnets for an office today? Also, it would probably help to have masks on those networks. Sorry.
Thanks for the feedback. This video was more on the showing the concept on how to apply VLSM on networks. Regardless of the class of the address , the concept and steps should be the same. I made this about 3+ years ago I think and this is more for answering exams coz I think back them subnetting and VLSM are part of Networking exams. And I made this video because people requested for it. I agree that it may not have practical use now.
@@EastCharmer "This video was more on the showing the concept on how to apply VLSM" - it does that very well and that absolutely has a practical use now.
Great video. But how about subnetmask? Is this stil /24 after all subbneting you did?
It is not.
Thx :)
You're welcome!
Hi ❤ thanks a lot for that. I am wondering how to do it when the number of hosts are 16000
Is there a shortcut for that?
you're welcome! It should be the same method. First we need to determine the number of host bits required to represent 16000 hosts. Then we need to determine the number of bits we should use for subnetting. This is by subtracting the host bits from the total bits of 32. Then last is we can determine the number of subnets and number of hosts from the subnet bits from step 2
nice video! the problem with the exam and stupid is that no calculator can be used! i don't know why they go at this level when even maths you can use the calculator in the exam...at work today everyone uses a subnet calculator anyway.
Thanks! Yeah I agree. They should test on how you solve problems and understand the concepts because like you said, in reality, we use calculator at work
@@EastCharmer in fact subnetting the concept can be understand, the problem is doing it mental is not easy, you need to memorize at this point since i hate calculations.
What if you have 32 users?
Do you go for the 64 because you need IPs for the default gateway and broadcast address or do you just select the 32?
Yes you have to go for 64 and always add 2 for the reserved addresses. Also when designing subnets it's best to think of scalability to make it easier to add more machines to a network when needed
@@EastCharmer thank you so much! I truly truly appreciate the help right now.
@@omesh5710 you are welcome!!!! I'm glad I was helpful
Would you make class B subnetting
How is VLSM done when network A needs to connect 325 hosts, b 215, and c 59 hosts?
In that case network A needs mask /23, network B needs mask /24, network C needs mask /26
Thank you it's an easy method but you forgot to state the new subnet masks
You're welcome. Yes I did. I was focused on the new network address. Sorry about that I will make a pinned comment for that
Can you assign private ip on interface that connects to wan
Generally speaking, no you can not.
I get the very beginngin part of it but I am so lost. I am trying to use this on Neil andersons course and I’m so lost
Which part are you struggling with??
@@EastCharmer let me restate what I said, this is by far the BEST video on VLSM. I am just confused at the 13:54 mark and beyond that. I also want to thank you so much for the response.
I guess my really big confusion is after you get done using the block number in the X amount of hosts what do you do then? Like if it makes sense, on the networks , why did you go from .64 to .80 , to 96 and then only use variables of 4? That’s where I am confused if that makes sense. I apologize I’m just REALLY just trying to better understand VLSM
um.. what about the subnet mask?
what is the answer fo the last network address?
Learning isn't easy when you're distracted by how pretty the teacher is 💀
Ma,am Plzz Spanning tree , and Reall environment, VRRP & HSRP use in reall Environment pls Ma,am
you 🎓🔊excellent
Thank you for the nice feedback!
so we have lots of address left, so let's say in a new place after we have done all this, we need 100 more host in this then how we have to do that.
Most likely, to be safe, you would probably make all these networks much, much bigger in the first place. She used these examples to illustrate how you would do it in theory. But running out of IPs to assign to your office is unlikely. There are millions of them at your disposal. But if you really need 100 more, just create a bigger network that does not overlap with any existing network you have.
please madam, wag mo sukuan tong channel mo. hehehe
hnd pa naman hehe
it was really hard to concentrate because of the big pair of distractions. But infofrmation was really helpful eventually.
