I think a better question to ask is whether Sprint and others who are
filtering out routes, forcing the issue of getting /19 blocks or not
getting portable space at all, are being Anti-competitive in the sense of
the Sherman Anti-trust act. By their actions the large network providers
are essentially limiting the ability of many small to mid-sized ISP
businesses from being able to compete in offering high-reliability (i.e.
multihomed) services to their customers.

This could be seen as an effort to limit the number of ISP vendors to the
big, national folks, and those who have existed long enough to have their
own resources (independent address space).

Folks have said the InterNIC, not being an ISP, is not in a position to
understand this issue, and that makes sense. The large ISPs are concerned
about the size of routing tables in their routers, and that is certainly a
reason to be concerned about having smaller independent address blocks. The
problem of large routing tables can be solved by making routers that
support more memory and/or routers that use their memory more efficiently.


The thoughts expressed here are my own ramblings and do not in any way
reflect any position, policy or opinion of my employer.
