Thanks so much! After watching bunch of videos from other channels, only this playlist helped me to bring all info together and now i start to understand this topic
There is some confusion on this video about the root servers. There are not 13 IP addresses, but 13 nameservers, as some of them have IPv4 and IPv6 addresses. Also, there is no such thing as "anycast addresses", they are normal IP addresses, that largely are reachable using anycast.
I don't agree with much of your feedback. There are not 13 name servers either . As I said, historically this was correct, but each root "NS" is not a single server anymore. Also keep in mind that these are 101 videos, I'm explaining these in a way which will help people understand. I take your point about ipv4 and ipv6 but I haven't covered ipv6 yet, and there will be many beginners who don't even know it exists, so complicating this explanation by using ipv6 as well is not optimal. Also your comment on any cast ... it's fair to say a unicast IP which uses IP anycast is an anycast IP. Again, keep in mind this is designed for beginners. There is no confusion, it's intentional abstraction to allow people to understand the DNS concept who might not be across all of the underlying concepts 100%.
I also disagree - while we know its a normal IP and "shared" using anycast, when using day/day language we refer to this as an anycast address. The same principle as saying the "gateway address" of something is x.x.x.1 even though technically its an IP address

The more I learn about how the Internet works, the more I don't understand it
