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.
One key concern is the space needed in internet routing tables. With smaller ranges, more entries are needed. The standing recommendation is to dish out /64, but providers also often use /48. -- Per Jessen, Zürich (10.1°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes
