So why don't you just use private IP space? That would require that we and our wholesale providers agree on a private block to use for this purpose. Even if this can be done, if/when we add another wholesaler, who's to say if they will agree to that space as well?
Personally, I would go with this option. That's what the space is for. I can't imagine it being that terribly difficult to negotiate this with your upstream(s), and if you need to change, it should be fairly trivial.
One of the wholesaler's we use in particular will probably make this next to impossible. I feel no need to mention names here, but they have been very uncooperative in the past and I don't expect them to act any differently in this situation.
Otherwise, why not just get real space from your upstream(s) and have them blackhole the route at their borders?
That's an interesting idea, and perhaps I'm missing something, but the only way I can think of that this could be done would be for the provider who has assigned this space to put a static route in every single one of their border routers. That is assuming that they assign me a block out of a larger announcement which would almost certainly be the case (unless they happened to have some swamp space they could give me). I doubt they'd be willing to do that since it's certainly not very scalable.
