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.
Let's say you are given 2001:db8:11:22
As you complete isolation, I presume physical networks, on your router with the four nics:
nic0 = 2001:db8:11:22::/64 nic1 = 2001:db8:11:22:a::/80 nic2 = 2001:db8:11:22:b::/80 nic3 = 2001:db8:11:22:c::/80
For instance, on my own network (at home), I use
2001:db8:4c68:1:ff99::/112 - known wifi clients 2001:db8:4c68:1:ff99:ffff::/112 - guest/unknown wifi clients
(not physical, just separate vlans).
Yes, I tried all of that Per. I just couldn't get it working with the Zyxel router that I had at the time. I remember documenting my saga on the OT list. It was one of those problems that had too many variables, so I just abandoned the effort.
It might well have been lack of dhcpv6. I forget we have one.
I don't see any clear reason to attack it again, except maybe for the challenge.
