IPv6 Multicasting by Dr. Chip

It was good to see him again ever since the IPv6 Essentials webinar he organized online the last time and the recent but different version of IPv6 Essentials webinar contained the involvement of nephos6 which is some other language for Cloud 6. This is some company he's working at and you can take some courses of IPv6 from there. Unfortunately, this is gonna be a tough kind of topic that I can barely understand even with the fundamental and essential level of IPv6. Perhaps, things look complicated and new to understand compared to IPv4 which I had already learnt back then but this is more or less the future technology and so far, I had already memorized so much of Windows OS Deployment with various tools. The tools I successfully used so far were the MDT, Windows ADK, etc. but I still ran into some learning problems like the network connectivity didn't work when it came to OS deployment through that so I did the local deployment with the custom ISO image to do the job but then, it seemed that I needed to activate the evaluation or something so that I could try the test OS for 90 days.
Since it's an online event, there may be possibility that I knew little things about IPv6 in technical details but this time, we got to know more things about Multicasting with IPv6 which is one of the most important methods of network communication. I believe that broadcast is of no more for IPv6 and the Anycast is the nearest version of Unicast. Like IPv4, the multicasting targets the multiple hosts in the group but not all depending on the content they are streaming from. Like the other methods of transmitting packets around the network, there may be multiple routes, hops, etc. like trying to reach the specific target hosts but you won't know where the packets are coming from at first. And if you don't know the basic and standard networking concepts, you will face deeper trouble like trying to understand IPv6.
Unlike IPv4, IPv6 opens doors to more networking types on the IP address such as link-local, site, organization and global. Obviously, all I got was like the link-local for IPv6 addresses back then and the public ones were what I didn't understand and know of back then when I gained IPv6 internet access. There are also multiple sources of where you get the IP address from.
From the ipconfig command, you can see the temporary IPv6 address and link-local in addition to the IPv4 addressing information. Plus, there are various terms of multicasting and this was where it will require taking some online courses of IPv6 through nephos6 if I want to understand more.
