Hello, I am thinking about IPv6 allocation scheme and I actually do not really understand what mean "allocating more tan one /48 for large subscribers only". There I should calculate HD-Ratio? For example RIPE NCC(for internal use i think) has /42? What it mean? Maybe it is just looking to make good hiararchy in future? Or what? Should I, making /48 allocation to average subscriber, reserve next one or two blocks looking to the future's better hiararchy? Tell your opinion or strict policy. best regards, Andrius
