Internic address allocation policy

Speaking from a (large) user organization. I am very concerned about
having the ISPs performing address allocation, particularly aggregating
addresses. As a user, I want to be able to change my service provider
if I get a better deal from a competitor or am having service
difficulties with my current provider. Today's technology for managing
addresses on individual computers makes it very hard for an
organization to renumber. Literally every computer administrator needs
to be in the loop. This can be a large loop when you have 13,000+
independently managed machines (like we do).

How do we users get our say to ensure that an addressing architecture
doesn't come into existence which tends to lock us into a particular

The entire point behind CIDR was to allow flexible sized blocks
of address announcements via BGP. The method of sending CIDR
blocks to a provider should not have any direct relation to the
provider's ability to handle "defections" of individual networks
within the block. I understand your concern, but it really is
pretty orthogonal to the problem of getting enough CIDR blocks to
providers to start with...
