MCI aggregates all its customer's routes into /19's. We have just
received our first block of address space from the 207.x.x.x range. If
you continue to filter at /18's for the 207.x.x.x range, you won't be
able to reach all of MCI's customers.
Needless to say MCI would appreciate it if you'd change your policy to be
/19's, and I'm sure Sprint's customers would appreciate it as well.
Regards, Daniel
