From my small knowledge of networking, I'm still looking forward to your video courses if you're willing to continue them, IPV6 and IPV4 are on totally different stacks. The client will try to resolve a domain name to an IPV6 then IPV4 usually.
So your provider gave you a generous range of IPV6 addresses however a lot of clients won't be able to communicate with those, are all those IPV6 also accompanied with a single IPV4 address. The coexistence between the two is kind of a hassle in this case as you may still require an IPV4 to have the box accessible for some persons.

I have no clue about your initial question.
