We don't really need a /32.  If we calculate need based on allocating
/56's to our residential and small business customers given our growth
over the last 10 years, a very liberal estimate would be that we'd need
no more than a /40 by 2020 (and probably far beyond).

Yes, as soon as either of our upstreams has it available, and if we are
still unable to obtain an ARIN allocation, we'll be requesting at least
two /48's.  The problem  then will be getting upstream A to advertise
and transport the traffic for destination addresses allocated to us from
upstream B, and visa versa.
