  • It should only be needed if your ISP is brain-dead and only gives you a /64 instead of what they should be doing and also giving you a /56 or /48 with prefix delegation (I.e it should be getting both a 64 for the wan interface, and a delegation for routing)

    You router should be using that prefix and sticking just a /64 on the lan interface which it advertises appropriately (and you can route the others as you please)

    Internal ipv6 should be using site-local ipv6, and if they have internet access they would have both addresses.
