How does IPv6 subnetting work and how does it differ from IPv4 subnetting?

IPv6 subnets are usually /64 because that is required in order for SLAAC (stateless address autoconfiguration) to work. Even where SLAAC is not in use, there may be other reasons to use /64. For example, there might be some end user devices out there that just assume /64, or else routing subnets longer than /64 might be inefficient on some routers because the router implementor has optimized the case of /64 or shorter routes in order to save routing table memory.
