Jeffrey -

  For sake of argument, imagine a large ISP which over the course of time has
  ended up with a /8, two /16, and a /14 IPv4 blocks (with the /14 being the most
  recently issued block because of nearly full utilization of all prior blocks at the

  Under present policy, the ISP cannot request address space until they have
  brought the utilization of the most recently issued block (the /14) up to 80%.

  Under the proposed policy, the ISP is immediately eligible to request space,
  since their aggregate utilization (even with a completely unused /14) is going
  to be very high (potentially as much as 97% due to the fully-used /8 block.)

  The proposed policy allows organizations to request space so long as their
  aggregate utilization is higher than 80%, and this means many existing
  organization with large IPv4 holdings will suddenly qualify to receive an
  additional allocation if they choose to request it.  Whether that is desirable
  or not is a matter for the community to decide.
