Hello Gerrit,

Indeed there is no single simple way to measure IPv6 adoptation. My "about half the world buy now" was just a rough indication in respons to Alex' remark that suggested IPv6 was just some niche protocol.

When we look at Fidonet, the list of IPv6 capable nodes presently has 108 entries. That is much less than half the number of unique entries in the nodelist, but with that we should keep in mind that the IPv6 nodes in the list are all or nearly all active nodes. Contrary to the global nodelist, there is very little dead wood in that list. So maybe the "about half" is not all that far off. Also, some or even many of the systems in Fidonet may be IPv6 capable without the sysop being aware of it. Except for the ones running very old hardware or some archaic OS, the systems themselves are IPv6 capable. Windows has IPv6 enabled by default since W7 and Linux is not far behind. Binkd supports IPv6 from versions above 1.00. Mystic and Sunchronet have followed. But contrary to the client only users, to run a fully fledged IPv6 Fidonet system one has to take some active steps. Like opening a pinhole in the IPv6 firewall. So there may be some Fidonet systems that could run an IPv6 node but still haven't enabled it.

BTW, I am a bit curious about your use of feste-ip.net in you host name. I an familiar with feste-ip.net, I still have an account  with them and I used it to experiment with their IPv4 -> IPv6 port forwarder. To be prepaired in case I ended up behind CGNAT.

So what is your connection with feste-ip.net? AFAIK you are not running an IOv6 capable node.



Cheers, Michiel
