Ah, a reason why Sprint's filters are self-defeating.  You would
be better off leaving sprint now, and going to a different provider.  Use
a /21 out of another provider's CIDR block.  If at a later date you decide
to multi-home with sprint, sprint's filters only effect small inbound blocks.
Sprint is more than happy to spew little blocks (so much for 'saving the
global Internet').

I've hear of a lot of crazy ideas from other NSP's, but not a peep of
any other NSP following Sprint's lead on filtering.  But suppose other
NSP's did decide to start filtering in the future, that's another reason
to get your own CIDR blocks from the InterNIC ASAP.  If you hadn't waited
this long, you could have gotten a block in 192/8 - 205/8, and wouldn't
have to worry about Sprint's filtering in 206/8.

Yes, it is perverse that the people most harmed are those that patiently
follow the 'rules.'  It is unfortunate that the IANA and NIC policies
seem to be creating a system that encourages people to jump to the front
of the line.  But folks, there seems to be nothing to gain, and a lot to
lose by being a good net citizen.  You don't get any brownie points for
being a nice guy.  You just get ignored.
