Baldur - 

    I am not aware of the RIPE practices with respect to IPv6 end-user assignments, 
    but in the ARIN region, ISPs/LIR's make assignments to end users based on similar 
    practices that the community adopted for ARIN’s end-user assignments.   To my 
    knowledge, ARIN does not review these ISP IPv6 end-user assignments (except 
    after the fact and in aggregate if an ISP were to come to ARIN seeking an additional
    IPv6 block due to utilization of the previous.)  

    Differences in policies between the regions is not necessarily any indication of a
    “problem”; it can just as easily be an appropriate reflection of different underlying 
    circumstances.
