Given my unusual network consisting of a dozen different telco's, I
actually assign each a /40 at a time, then /44-48 in each of their pops
depending on expected growth. I probably could have possibly gone with
/36, but then I limit my own allocations to them and I'd like to hope I
get more telco's in the future. I do sparse allocation on the /40's to
allow smaller routing tables if desired, though. Even for things that
don't need nibble boundaries for technical reasons, I usually maintain
them for ease of management and scripting.
