With how trivial generating new addresses in IPv6 is, it'd be cool to have a host block all incoming traffic on its own and have each service that deserves to be reached over the listen on an address unique to the service.

You're right, they are one level above. > Hosting service A shouldn't mean that every user of service A can also figure out you host C, B and D. It how are ports on a single IP address essentially different from multiple IP addresses within a subnet?
- eptcyka 2y agoIn a /64, enumerating all hosts will not be as practical as enumerating all ports on a single IP. Further, you will not be able to link that two services are running on the same host by just the IP.
