> If you have 10k (say) users on CGNAT that are compromised, it's likely that there's at least 1 on each CGNAT IP. This means you can't just null route compromised IPs as you are effectively null routing the entire ISP.
How about we actually finally roll out IPv6 and bury CGNAT in the graveyard where it belongs?
Suddenly, everybody (ISPs, carriers, end users) can blackhole a compromised IP and/or IP range without affecting non-compromised endpoints.
And DDoS goes poof. And, as a bonus, we get the end to end nature of the internet back again.
