Please tell me when and how that will happen. I'll be sure to let 
management know!

In all seriousness, I do not ever expect a company of my size and 
business model to need more addresses, but if I do, ARIN staff have 
already planned ahead:

2610:b8::/32 - allocated to me

The next block of allocated addresses is 2610:c0::/32, which means that 
potentially I could grow in to a /29 without renumbering or creating 
additional routing slots - until they need to allocate those blocks to 
someone else.

The point is if you assign your addresses based on future need rather 
than current need (which I believe is the wisest approach), then you 
have to ability to maintain a more static network, and a more stable 
routing table, among other benefits.
