Unfourtunatly the Canadian IP registrar has been handing out addresses in
the 22.214.171.124/16 range to anyone applying for a IP address in Canada.
Sprint has several Canadian customers Sprint Canada, Cyberstore, and Hookup
that are anouncing routes to you in this block.

The following are the addresses of my customers that would be filterd by
this policy. None of these people were told that these addresses could only
be routed to CA*net.
[ prefix as-path ]
126.96.36.199/23 3561 5071
188.8.131.52 3561 5071
184.108.40.206 3561 5071
220.127.116.11 3561 5071

Thanks for the warning. I understand your reasons for this, unfourtunatly
the Canadian IP registrar may have been unclear on the concept.
