Thank you for the clarification.  I am obviously in the very early stage
of planning IPv6 for our company with hopes of at least having peers up
this summer after our peak holiday season (mothers day).  I would prefer
to get an ARIN block so that we feel less locked down to a provider by
using their space.

So what seems to be the standard for the longest advertised prefix for
v6 (compared to /24 for v4)?  If I get a /48 from ARIN how many
non-aggregated prefixes should I expect to have?  This sounds like you
are saying /48 is as specific at it would get.
