They way you ask it feels a little bit like it should be everybodies duty to
have IPv6 connectivity.

Any suggestions how to best find these articles in 520 zip files?
(last decade means 2000 to 2010?)

My parents switched from Telekom (6 Mbit/s) to Innogy (50+ Mbit/s). The new one
uses an IP from the 100.64.0.0/64 range. First I didn't know that these are
non-public IP addresses and wondered why port forwarding in the router didn't
work.

Yes, not enough IPv4 addresses for a new provider.

Experiences shows that asking the customer support for IPv6 does not change
anything. Switching the provider is often not an option or has other
disadvantages.

Not really secure.

Yes, that works too.

I see your point, but why are the connection methods mutually exclusive?

I think I do appreciate it. In my definition of "universal connectivity" a node
(or point) should be reachable everywhere even when it has no public IP, is
behind a firewall, CGN, switching between networks, etc ... I think overlay
networks like Tor or i2p are a good fit for Fidonet. Maybe IPv6 will solve all
connectivity issues soon, but I wouldn't hold my breath ...

 MvdV> Whatever... you have not answered my question: Hoe is your IPv6?

Could be better ...
