Really? What is their new policy? Suppose you can only fill 60% of a /19 ... do they give you a /20 (with permission to announce the /19) and force you to use provider space for the other 819.2 addresses that you need? My point is this: 100% of a /20 is 50% of a /19 ... so if you justify need for more than 50% of a /19, that should be jutification for a /19. (less than 50% of a /19 could be satisfied by a /20). (and likewise for other sizes, both larger and smaller than /19). Does ARIN not see it that way? - Brett ([email protected]) ------------------------------------------------------------------------------ ...
