IPv6 from scratch – the very basics of IPv6 explained
The basics of IPv6, IPv6 addresses, IPv6 scopes – kind of IPv6 for dummies 😉 I took a looong IPv6 course on Udemy in order to learn the very basics of IPv6 – but – I was struggling with it. Until I feed up my mind and forgot everything I knew about IPv4 – from then on I was able to learn IPv6 from scratch 😉

0:00 I struggled with udemy
0:56 The plan: forget everything you know about IPv4
1:15 Let’s design addresses
4:00 We design Protocols (UDP, TCP, ICMP)
5:44 How do we “bootstrap” IPv6 (SLAAC)
6:20 Let’s go larger (Scopes)
7:45 How to determine scope (Address ranges)
9:49 What if the scope changes? (multiple addresses)
10:46 Networks (subnetting, prefixe, delegation)
13:03 Some IPv6 tools

Thank you thank you thank you!!! Such a clear and well explained video!
wow IPv6 is amazing. I never really liked it because I didn't understand and looked confusing, but after your explanation I almost want to remove IPv4 from my stack hahaha
ABSOLUTELY the best one of these I have ever watched…and there have been 100s. I love how you break it all down, and I too struggle with differentiating IPv4 and IPv6. I am still struggling with IPv6 (in my home with pfSense as router and a Windows 2019 server ADDS/DNS/DHCP setup). I cannot get that server to hand out addresses (well I can – but they cannot get to the Internet over IPv6 only (every test site I visit shows IPv6 failures). Looking forward to your other videos, and maybe I can figure this out. 👍
I could kiss you right now! Thank you for breaking it down for the rest of us
Thank you much for the easy simplified way of delivering that content
I do recommend you to teach on udemy your courses will be very good add to the tech community
Great introduction for the IPv6 world. Thanks for sharing.
This explains the basics so well! Note to self: don't ever try to understand it in IPv4 terms again.
super easy
thanks from Kurdistan
Ugly IPv6 LoL….
Do I call you Mr. White or Heisenberg?
i never thought about it but I also try to translate what I know about v4 to v6.

This was really helpful. Building it up was a great way to help me understand why it is the way it is!
I am studying CCNA cert. This IPv6 explanation is really cool in real world. Other instructors just use 2001:db8(which is used for documentation purposes) and leave everything else.
Great
Very nice intro, thanks!
Thank you for these IPv6 videos. One thing I can't get my head around is my perception that there is a lack of privacy. For example, when you browse to a website, does the website see the complete IPv6 address for the client, or just the WAN portion assigned by the ISP? Does the ISP know what devices you have on your LAN? How do you handle port forwarding? I assume you would still need to open ports on your router's firewall and on your client's software firewall.
All of these privacy related questions are fairly simple in IPv4, although, I do understand they are byproducts of NAT, which apparently is a bad thing (though I like it for network segregation and privacy). What am I missing here with IPv6? Why do the LAN clients even need to be aware of the WAN IP from the ISP?
Awesome video. I've finally started to understand ipv6 🎉
Thank you
Superbly clear – thanks!
Thank you for making this video and sharing it with all of us! I have been putting off learning IPv6 for a long time now. This was exactly the correct video for me to find and get motivated to get back into learning this. I am of course, subscribe with notifications turned on, and that was it up.
