Interesting point about /64 vs VMs. I solve it by running OSPF on VM hosts (even laptops), but that is very cumbersome and relies on IP redirects. I suppose I could re-number to /60. I'm on RFC-4193 anyway.

BTW, I used IPv6 NAT for years and years. It became because the support for DHCPv6 in Fedora had critical bugs, and because some providers did not support DHCPv6 at all. I was only guaranteed to have 1 address, therefore NAT. My current provider gives out a /48, but NAT works, so there's no point in avoiding it.
