I had an interesting discussion with someone from Registration Services at ARIN today.
The big requests for IP space (the 11 organizations that hold 75% of all ARIN issued
space) do not come from the server side... They come from the eye-ball ISPs. The only
/8 issued by ARIN to an ISP, for example, was issued to a cable ISP.
With this in mind, I don't think there's much to be gained here. Optimizing the utilization
of less than 25% of the address space in the face of the consumption rate on the 75%
side simply cannot yield a meaningful result. It really is akin to rearranging the deck
chairs on the Titanic.
