The problem I see with that is LIRs would be motivated to make as big a
land-grab as possible, and ARIN would have no metrics at its disposal to say
no -- certainly not the unquantifiable "giggle test". What if Comcast,
AT&T, Verizon, Cox, etc. said they planned on giving a /32 to every customer
and thus they needed a /3 each? What tools have you given ARIN staff to say
This is not implementable. Leo's idea, while it may not be perfect, is. We
need to give clear rules to staff so that they know whether to approve or
deny requests and they have solid documentation to point to when doing so,
or we'll end up back in the same boat we're in today where ARIN approves
everything because we haven't given them any guidance on when they shouldn't
(or, if ARIN turns evil in the future, denying everything for the same
