Re: IPv6 Default Allocation - What size allocation are you giving out

I've been using /36s per location, but hm -- great question.

How easy is it to get a larger allocation anyway? In RIPE, i.e: you just ask and get a /29 with no questions asked.

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.

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 ?
