Hasn't IANA and ICANN basically given ARIN the task of managing IP space?
Perhaps I have missed something. Of course it should have IANA's and
ICANN's blessing. Why should ARIN have to be dictated first by ICANN? I
have no clue what goes on at ICANN, but I have a suspicion that the people
in and around ARIN are more in touch with these issues.
Let me put it to you this way... A father asks that his teenage boy to
help with more of the yardwork. "Where do I start dad?" The father
instucts the boy how to mow the yard. Upon mowing the yard the boy sees
that by trimming some of the weeds around the fence the condition of the
yard would look much better. The boy decides to ask his dad if he can
trim some of the weeds that the mower couldn't reach. Dad is pleased.
The boy is pleased. The neighbors are pleased.
Obviously the weeds are those unused legacy IP blocks. ARIN should draw
up a simple game plan, get all the appropriate parties blessings, and at
least make another attempt to get that IP space back.
If a company needs a smaller block, I say give it to them for free. If in
the next 5 years they find out they need more IP space, give that to them
for free too, but have some sort of time limit on the free IP space.
As far as your global comment, I doubt that many African, Asian,
Australian, South American, etc. entities are sitting on lots of large
unused blocks, but I certainly could be wrong. And what if I am? Why
can't ARIN still do it? Why can't they become a model for the process if

Are you saying that ARIN's resources are so strapped they can't blink and
breath at the same time? I find this extremely hard to believe. If
testing IPv6 in the manner you suggest is agreed to be useful, why can't
ARIN do both?
