With current policy you should. But there is a movement of thought towards /56's becoming the standard. > or do I get a link local address, using which I can use some (which?) > protocol to get my own (do I need a fixed one, yes I think so) /48 prefix? DHCPv6 with Prefix Delegation is what you are thinking about. http://playground.sun.com/pub/ipng/html/presentations/march2002/DHCP-PD.pdf Though it is probably easier for the ISP to just point the /48 to a fixed IP address on the uplink. Which is basically what SixXS does. In my home network (see http://unfix.org/~jeroen/network/), I already have this setup. The /48 is simply routed to my gateway. Same for IPv4 as for IPv6 ;) For giving IP's to the boxes on the network I use DHCP for both IPv4 and IPv6 btw. Greets, Jeroen
