Just like to throw an interesting wrench into this whole discussion.
Our current allocations are a /18 and a /19.
Although we are growing fairly quickly here, we're actually seeing
negative address utilization here.
The reason?
We started to recommend to our larger customers that their
newly-redesigned switched 100Mb/s plus really-flat network might be better
served by the 10/8 or the equivalent /16 and /24 address blocks with a
proxy server. Better security, less address space utilization.
When a customer who you allocated a /20 to releases it back after
renumbering into one of the 10/8-type blocks it makes a big difference
when your total allocated space is only equivalent to 6 /20's.
Of course, this is only a temporary reduction, as we are adding several
POP's this summer which will consume more than has been reclaimed.
I would be interested if anyone else has seen anything similar.
