[arin-discuss] IPv4 allocation conundrum

[Erik Levitt]

Randy,

ARIN should approve a /21 immediately if they are legitimately using it
and it can be SWIPed properly.  If you get 4 /24's from two providers in
addition to the /21, then you have a /20 worth of addresses, which means
you can apply for the /19.  

You can usually use private address space to justify public space with
ISPs.  

Given that I work for a VoIP interconnections provider I sympathize
about NAT.  Although some suggest that NAT transversal is elegant, I
would be to differ after watching customer after customer struggle to
make it work.  On the other end, given the lack of address space
resources left I sympathize with ARINs policy.  I wish that more people
would adopt v6 faster as we can't go to v6 on our edge until every
single one of our customers supports it, but I digress.

Regards,

Erik

This seems futile when the absolute minimum they can get by with in the
short term is a /20.
