See my other email.

You don't need to use a providers range.

DNS is great, but there is plenty of stuff to change that doesn't use DNS (ACLS, etc...). The point is, why should we go through the pain of renumbering, and have to do it everytime our relationship with our ISP changes? We aren't going to go there. It isn't renumbering that's the problem, the problem is that it being tied to an external company.
