> It's each internet connection that gets a /64,

i get a /48, which i can delegate the prefix to 255 subnets of size /64, so each machine on my LAN gets a /64 this is Prefix Delegation, part of DHCP v6 aka DHCP-PD

edit: this is still "new" in that half the consumer routers only partially support it. but afaik it was in the spec for ipv6 that each node should be a /64, so realistically my LAN having each node with /64 is per spec, and machines that are NAT behind a single /64 at the gateway are out of spec and part of the reason that no one uses ipv6, IMO...
