I am not sure I agree with this.
We are annoucing a /24 from the 66 /8 block and I have only found 2 =
ISP's=20
(according the the netlantis project) that can't reach me.
We are multihomed. I suspect that may be due to aggregation.
But even with our backup online, I still saw the routes propogate via=20
Netlantis..
Or am I out in left field going nuts?
