According to ARIN, _IF_ you meet their requirements for obtaining an IPv4 block, then, you ALSO automatically meet their requirements for obtaining an IPv6 block.
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.
However, there is a specific block being used to issue ARIN end-user assignments, and, many ISPs filter that more liberally (/48) than they filter blocks used for allocation (/32). As such, your customers who are multihomed _MAY_ have a better chance of having their prefix seen if they use an ARIN direct assignment.
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.
