Even with link local addresses, the number of reachable addresses is limited by the subnet size and is usually a /64. Here's an example, taken from the computer I'm using right now. fe80::76d4:35ff:fe5b:f5fa/64 scope link
This is off-topic. I've always wondered why /64 was chosen for the default IPv6 netmask. It seems to be a horrible waste of IP address space. Sure, no problem now, but what about 100-years from now when the Internet may extend to the moon, mars, the asteroid belt, and beyond? I'd think that /64 of subnet address space will always be wasted. Where am I wrong?
