Question: Should we be asking ARIN for another /32 so that each network has it's own /32 or should be break out the /32 into /36 and use these in each of the geographies ?
Depends on your needs… Either is a viable solution, depending on your circumstances. ARIN has an MDN policy which would facilitate your acquisition of a second /32.
Thank you Owen, just got off the phone with ARIN, it should be a fairly simple process for us, and we will follow the advice of using a /32 for each geographical location. The overall discussion has been a very interesting one, and it would appear that the majority of the forward looking opinion is to allocate /48 to customers, and don't do any smaller subnet allocation. We will take this advice and re-evaluate our policies. Regards.

Selection of a default prefix is easy. Here are the steps.
4. Keeping in mind
4.1 Prefixes longer than somewhere around /48 to /56 may be excluded from the global routing table
4.1a Prefix cutouts of any size (including /48) from inside your /32 or larger block may be excluded from the global routing table. Folks who are multihomed and thus need to advertise their own block with BGP should be referred to ARIN for a direct assignment. Folks who aren't multihomed, well, until given evidence otherwise I claim there are no single-homed entities who will use 65,000 LANs, let alone more. =============================================
This brings up another interesting question...
We operate Two separate networks in two geographical locations (Two ASN), we have a single /32 allocation from ARIN.
