Now, IPv6 is the future, therefore CIDR notation has been introduced. It concatenates the IP with the network prefix mask in one bit - identifying a host on the subnet - using a backslash; and this is used today.
1) Did you ever hear of privacy extensions?
2) What does CIDR notation have to do with this? That's nothing new, it has been used with IPv4 addresses for ages - as anyone following the blacklist thread or maintaining a server would probably know.
3) How is this even relevant at all, given the fact that AC doesn't even have IPv6 support yet?
