Thing is, I'm an end user site. I need more that a /48, but probably
less than a /32. Seeing as how we have an AS and PI, PA isn't going to
cut it. What am I supposed to do? ARIN suggested creative subnetting.
We pushed back and got a /41. If IPv6 doesn't scratch an itch, why

There are plenty of high-profile end user sites in 2620::/23. Some
government (CIA), some popular (Facebook.) I don't think Verizon's
stand is going to last.
