Is this a viable solution nowadays? I mean, anything smaller than /19 won't get propagated to the rest of the world anyway. Also, I've never had any luck convincing two providers to somehow work together to solve a "small problem" like BGPing a small /24 block of addresses with their so called "competition" (at least here in Europe, anyway.) Perhaps, it's different in the US? Of course, if Albert is indeed talking about a /19 block, then this isn't an issue, his ISPs probably wouldn't want to lose him, and you can forget what I just said :) -Paul.
