My Zyxel router has one check box to enable/disable IPv6, I've seen no reason to enable it myself. I played around with it a couple of years ago but could only get a /64 address from my ISP. I wanted at least a 62 because I use three subnets and I want them completely isolated except for a router management port. Maybe it can be done witha /64 but I couldn't figure it out
You do it exactly as you would with IPv4 - classless subnetting. That /64 can be subdivided into virtually whatever you want.
/64 prefix is ingrained deeply in all IPv6 protocols, anything else will make normal autoconfiguration using RA (SLAAC) impossible. So, you will need to use manual configuration or DHCPv6 to assign addresses. Something to keep in mind.
