Number all your internal infrastructure with a ULA-L block
as defined in RFC 4193, and get another ULA-L block to
reuse for every customer. Yes, it means that they will
have problems doing P2P with each other, but that's life.
Then get a /48 block from your upstream. All this is free.

Screw ARIN and their price lists, screw arguing and bickering.
Skip the agravation and go straight to your upstream and your
RFC 4193 blocks. Use this tool to help you choose your ULA-L
prefix: <http://www.sixxs.net/tools/grh/ula/>

Let the big boys play ARIN games. You don't have to.

The fact is that there are options out there, and not
everybody needs to follow the same piper. Diversity is
