This is lovely for end users but for server admin, how do you firewall countries for IPv6 without memory exhaustion?
Differently from IPv4, IPv6 addresses are strictly hierarchical. You block areas by blocking their root network.
Now, why do you need to firewall entire countries again? Are you working at the Great Firewall of China or some similar project?
GeoIP blocking is not one's only defense, of course, but it's one of many tools to keep the low-to-mid level groups at bay.
But yes, this type of blocking with IPv6 should be eaiser.
Your firewall rules will actually get smaller!
