Just got back into Fidonet and looking around and since I have automatic 6in4 from my ISP I figured I'd give this a shot.
I'm using a Netgear R7000 which supports a few types of IPv6 and it auto-detects as 6to4 tunnel.
I have set up a couple of AAAA-records pointing to my BBS/Binkp-computers ipv6 adress but I don't have any ability to test stuff since I don't have access to any other IPv6-connected machines to test from.
bbs.beyond.nu should answer on 23, 24554 and hopefully pings on it's IPv6 adress, if not well either the router or my ISP is doing something wrong. Or more likely I am. :)
I have looked around for some info on Netgear and IPv6 but the information is scetchy at best.
