As I understand it, public IPv6 addresses allocated by the IANA will have the prefix 2000::/3. These ip addresses will be routable through the Internet. IPv6 multicast addresses on the other side are prefixed FF00::/8. So my understanding is that the ipv6 multicast addresses won't be routable through the internet. I am right? If so, is there any way to do one-to-many ip routing over the Internet in IPv6? Thanks!
