Re: [**EXTERNAL**] Re: the race to the bottom problem

["Joel M. Halpern" <[e-mail]>]

Jorid, from what has been said, some ISPs do not use DHCPv6.  that's 
fair.  We actually told them they did not have to.
So I do not think it is fair or appropriate to claim that to solve the 
delegation problem they must use DHCPv6.

     What is not clear to me is why solving the delegation problem 
requires extending the allocation boundary past /64.  The draft on the 
v6ops agenda simply asserts that it is necessary.

Yours,
Joel
