Hi David,

A) 6rd is not necessarily a transitional technology. Certainly the
NRPM does not define it so. If I say my use is permanent, what basis
would ARIN staff have to disagree?

B) The concern expressed in the policy proposal was for *initial*
justifications. Even if ARIN determined that 6rd could account only
for a /24 of efficient use for a *subsequent* allocation, the
addresses would already be gone in the initial allocation which places
no such constraint.

Regards,
Bill Herrin
