I sense some kind of fundamental problem in this discussion.
>From -my- point of view CIDR -is- deployed:
- we've been allocating from provider blocks for probably two
years now, and the number of prefixes announced has been
growing -very- slowly (with respect to -new- allocation
of addresses), even with customers not returning their addresses
when they leave us. Do you have -any- hard data that anything
else is happening at a global scale?
- there is naturally a tendency for the provider address space
to fragment over time, however do we have -any- data that this
is causing any of the problems we are seeing (it surely isn't
creating a large increase in prefixes -now-)?
- nearly -all- of the prefixes we announce are pre-CIDR allocations
(B and quite a large number of C's (that we are trying to clean
up)), I don't believe this to be different with any other ISP.
Yakov, if you have data that CIDR is -not- working for new allocations
please present it here.
