Since this is NANOG, I'll restrict my comments to ARIN policy: > Unfortunately RFC2050 doesn't address at what point additional address > space should be assigned to an end user, however, it never uses the > 80% figure in that respect. Interestingly, ARIN doesn't publish any policy on additional address space assignments to end-users. However, I can tell you that in practice (and it's common sense, too) ARIN does not issue additional assignments to end-users until they demonstrate that they have used their previous assignment efficiently (80%). Why? Because: > This means that if they are already at 50%, you assign them another > block equial in size to what they have, and they reasonably expect to > double their utilization in the next year, that everyone should be > happy. You can't use 25% of the additional block immediately if you still have 50% of the initial block available*. Again, though it's not written down (Richard Jimmerson?? Comments?), ARIN does not issue end-users additional blocks until their existing blocks are efficiently utilized. /david [*] if you can, you're a special case that's not material to this discussion.
