I think #3 comes closest.

I am not sure about the /64 for the link. The only visible part of the link is the IPv6 WAN address of the router. It is outside the /56 assigned to the user, the link may just use a /128.

The modem/router supplied by the ISP assigns one /64 for the LAN and another /64 for the guest network. More /64 out  of the /56 can be obtained by connecting extra routers.

For IPv6 one must use the modem/router from the provider. When the modem/router from the provider is set in bridge mode, the connection becomes IPv4 only.

My provider is Ziggo. A daughter from Liberty Global.


Cheers, Michiel
