Dude I've been looking forward to the day I finally could find a channel where I could understand clearly these kind of things. Keep it up with the good work and effort that you put into the videos man, I appreciate all the knowledge that you share with this community ! Thanks!!
Thank you so much! I'm writing some code to do subnetting for ipv6 and I needed to understand how to calculate it by hand. And I can't find a good description anywhere until I stumbled upon this video. THANK YOU!
Thank you so much for your kind words! I'm thrilled to hear that you found the explanation and examples helpful. If you ever have more questions or need assistance with anything else, whether it's tech-related or any other topic, don't hesitate to reach out. I'm here to help! 💯😊
how would you connect different countries of the offices, definitely through different ISPs in different countries? won't you get /48 prefix from each ISP in different countries? A network design topology and including multi ISPs in the picture would definitely help to understand the high level concept. and also Which IPV6 address to be given to the ISP facing router?
I love your video tutorials. Even though this video is just about Subnetting IPv6, which in fact is taught marvelously, I still wonder (even though it might be obvious) how to determine the ranges of usable hosts (I guess, it is Network Address + 1 ... Broadcast Address -1 of each subnet).
In IPV6, there is no Broadcast Address in the unicast address space, and the Network Address can be used. It is not as useful to determine the ranges of usable hosts, as most of the time, the range is so large, you won't have to worry about. The range, if you want to know, is from the all-zeros interface id to the all-ones interface id, which can support 2^64 hosts.
So essentially offices are talking about different locations. For example, maybe your company has an office (location) in Sydney, Singapore, England. Thus, an office is just a different geographic location. All our videos have captions if that helps.
IPv6 subnetting is not like subnetting in IPv4. The subnet ID is a fix 16 bits of the IPv6 address. The only time you use a slash is for the prefix to determine different networks which is used for routing. So you are free to allocate the 16 bits however you want, once you run out, where you run out. So if you are up to /61 (That is have 3 bits left) you can add up to 8 networks if you use all the bits.
Hopefully I'll get an answer here: What if I had 3 countries, 40 states, 43 cities with 2 offices per city? I would have a /50 for countries. [ 3 countries = 2^2 - Leaves us with 14 bits. (64 (subnet bits) - 48 (fixed bits) + 2 (new bits)) ] I would have a /56 for states. [ 40 states = 2^6 - Leaves us with 8 bits. (64 - 50 + 6) ] I would have a /62 for cities. [ 43 states = 2^6 - Leaves us with 2 bits. (64 - 56 + 6) ] I would have /63 for offices. [ 2 officers per city = 2^1 - Leaves us with 1 bit. (64 - 62 + 1) ] For countries, the address would go up per 4000. For states, the address would go up per 100. For cities, the address would go up per 4. And for offices, the address would go up per 2? For my example below assume: 1. Canada - 2001:db8:cad:0000::/50 2. America - 2001:db8:cad:4000::/50 3. UK - 2001:db8:cad:8000::/50 Would that be: 2001:db8:cad:4000::/50 - America ----2001:db8:cad:4100::/56 - CA --------2001:db8:cad:4104::/62 - San Francisco ------------2001:db8:cad:4104::/63 - Office A ------------2001:db8:cad:4106::/63 - Office B --------2001:db8:cad:4108::/62 - San Jose ------------2001:db8:cad:4108::/63 - Office A ------------2001:db8:cad:4110::/63 - Office B --------2001:db8:cad:4112::/62 - Sacramento ------------2001:db8:cad:4102::/63 - Office A ------------2001:db8:cad:4114::/63 - Office B Is that correct?
It looks correct as far as I can tell it looks correct. I would probably run it through an online IPv6 subnet tool to check the subnet are correct. You don't have to use all the bits, so having one left over is o.k, having said that you could use that in another area if you needed to. At the end of the day, even if you have more expansion in one area then you originally planned you can use another network from a different subnet, it will mean you will just need to create more routing rules.
@@itfreetraining I was trying to work my way down with my own examples. I am currently doing a Cisco curriculum and they just explained the easy way (increasing by 1), and I didn't like that. Thankfully I found your video. Very well explained. Thank you about that.
Best explanation i have come across!!!Thumbs up Boss
Much appreciated!

Best explanation of IPv6 subnetting so far in a pleasant voice
The things i´ve learnt from this channel far outweight that of my school . I do appreciate your efforts guys.
Awesome explanation, brilliant examples, clear conception...... simply awesome 💯

God bless you my man, this was amazingly easy explanation!!
Thank you!
easy to understand how to split subnet!
Great explanation of IPV6 subnetting-Thumbs up
Thanks for watching.
thank u so much for your great video, very clear explaination
Thanks for watching.

Thats where AS number comes in its above isp
Very good and easy to understand! Ty a lot
thank you for the presentation . thank you thank you
Our pleasure!
thanks for very helpful tutorial
Glad it was helpful!
Great video, very well explained. Well done!
Thanks very much.
Thank you so much sir.. Thank God that you've been blessed with the knowledge I pray to God that He increases your knowledge. 😊❤🙏
amen

any idea how to find ipv6 ip address?
If you run IPConfig /all this will show you all the network configuration including your IPv6 address.
Hello im not english native and i dont understand how large or what mean with offices
So essentially offices are talking about different locations. For example, maybe your company has an office (location) in Sydney, Singapore, England. Thus, an office is just a different geographic location.
All our videos have captions if that helps.
Thank you so much professor, very helpful
how did you get 8000 im not understanding. i watch it over and over
but what if your subnet mask is /61 you need to add 5 subnets so it is 3 bits which makes your mask /64. then you have no "space" for the subnet id
IPv6 subnetting is not like subnetting in IPv4. The subnet ID is a fix 16 bits of the IPv6 address. The only time you use a slash is for the prefix to determine different networks which is used for routing. So you are free to allocate the 16 bits however you want, once you run out, where you run out. So if you are up to /61 (That is have 3 bits left) you can add up to 8 networks if you use all the bits.
ok Nevermind i finally got it. its currently 1 am
Glad we could help.
It's verify good example!! Excellent!!! Congratulation!!!
Thank you!
FYI: @3:42 --> 2^15 = 32768
Why don't you simplify the equation to i = 2^r?
That would be easier, however wanted to show what would happen if some if the bits were already allocated.
Well explained, thank you
Thanks for watching.
Great video!
Glad you enjoyed it
great job bro..!
Thanks!
so to master is this field, you gotta know your mental math well. Time to reshape my brain.
Omg thank you so much!
Thanks for watching.
Hopefully I'll get an answer here:
What if I had 3 countries, 40 states, 43 cities with 2 offices per city?
I would have a /50 for countries. [ 3 countries = 2^2 - Leaves us with 14 bits. (64 (subnet bits) - 48 (fixed bits) + 2 (new bits)) ]
I would have a /56 for states. [ 40 states = 2^6 - Leaves us with 8 bits. (64 - 50 + 6) ]
I would have a /62 for cities. [ 43 states = 2^6 - Leaves us with 2 bits. (64 - 56 + 6) ]
I would have /63 for offices. [ 2 officers per city = 2^1 - Leaves us with 1 bit. (64 - 62 + 1) ]
For countries, the address would go up per 4000.
For states, the address would go up per 100.
For cities, the address would go up per 4.
And for offices, the address would go up per 2?
For my example below assume:
1. Canada - 2001:db8:cad:0000::/50
2. America - 2001:db8:cad:4000::/50
3. UK - 2001:db8:cad:8000::/50
Would that be:
2001:db8:cad:4000::/50 - America
----2001:db8:cad:4100::/56 - CA
--------2001:db8:cad:4104::/62 - San Francisco
------------2001:db8:cad:4104::/63 - Office A
------------2001:db8:cad:4106::/63 - Office B
--------2001:db8:cad:4108::/62 - San Jose
------------2001:db8:cad:4108::/63 - Office A
------------2001:db8:cad:4110::/63 - Office B
--------2001:db8:cad:4112::/62 - Sacramento
------------2001:db8:cad:4102::/63 - Office A
------------2001:db8:cad:4114::/63 - Office B
