ARIN implemented a policy in February (based on a recommendation from
the Advisory Council) for multihomed organizations.  Basically, if you
are multihomed and you meet the following criteria:

- efficiently utilized a /21
- can justify more address space
- agree to return the /21 to whatever organization you received it
from within 18 months

than you may be issued a /20 from a reserved /19 from ARIN.  The idea
is that you may announce the full /19 but you cannot use any of the
second /20 until you go back to ARIN and justify it.
