Absolutely.  IP (the internet) has been around for more than
three decades.  It is the responsibility of an internet router
to route ip traffic.  The internet belongs to the world.  If a
provider chooses to not route traffic, then that is their loss.
They will not last long.  It should not be ARIN`s responsibility
to keep only providers happy.  A compromise must be found.

I would like to have a non-routable /24.  Since you think the
prime issue is about routing table size, then maybe ARIN could
set aside address space for non-routable /24s.  Then both of
us would be extremely happy.  How`s that for a compromise?

So, we should just leave all of these addresses _reserved_
forever?  Or only available to the fortune100?  All because
routers are slow?  Make /24s available to small businesses and
router vendors will be forced to make it scale well.

>Most small business don't even have 15 hosts, let alone 254 of them.

Which companies did you poll?  My numbers would be significantly
different.  But I do not have facts, so I will not publish them.

Obviously I disagree.  Providers will just have to upgrade their
routers.  ;)

So what if we run out of IP addresses.  If I can`t get one because it
is _reserved_, it may as well be non-existent.  Don`t punish me.
Make policy that gives ARIN teeth to go after wasteful corporations
to get unused space back.  All of these addresses are currently in
the routing tables; aren`t they?  Maybe providers should remove
these addresses from their tables.  That should speed things up
a bit???
