RE: 64.0.0.0/8 etc. [was: Re: BGP Question - how do work around...]

There are plenty of folks who have space in 64/8. However, no one should be
classfully advertising 64.0.0.0/8, as it has not been assigned to any single
entity. Therefore, anyone who is advertising this block is doing so in
error, and it's permissible to filter the EXACT 64.0.0.0/8 route
announcement. (as opposed to filtering "64.0.0.0/8 or longer", which would
blackhole many folks)

Aren't many Earthlink dialups in 64/8?

Filtering that would mean his employees couldn't get Sprint DSL, and
prevent millions of potential customers from reaching his web servers.

That's not smart business.  It's called "cutting off your nose to spite
your face."
