Premium Rate IP's
What if you could op-out of some IP ranges at the ISP and one of those categories is "Current DDOS" targets. If that was the default a company could flag itself under attack and then many IOT devices fall off the team at the ISP.
The real user could then be redirected to a proxy so valid requests to important sites under attack can be made but rate limited (to avoid the DDOS achieving it's aim to taking the website down).
