 KK>> That's fido IPv6 relay for binkp and ifcico I made just for lulz.
 MvdV> So this is an IPV6 to IPv4 gateway.

Actually, it isn't strictly IPv6 to IPv4. IPv6 to IPv6 also works. And if destination IPv4 addresses are unresponsive IPv6 addresses also will be tried.
So it is potentially can be used to reach IPv6-only nodes if direct routing isn't working for some reason.

 MvdV>  IPv6 only nodes can use this to connect to IPv4 only nodes. Wow!.

Or IPv4 only nodes could use such services to advertise IPv6 reachability when don't want to mess with IPv6 tunnels or their retro-OS doesn't support IPv6 at all.
Or just want a shiny f1d0-style address but can't have one...

There are could be numerious hypotetical reasons for such services to exist.

 MvdV> I do not know what problem this is a solution for, AFAIK there are
 MvdV> no truly IPv6 only connections yet. Every end user on the internet

As I have already said that experiment was just for fun.
I've tested how recent linux kernels handle thousands of address aliases on interfaces in memory constrained environment.
I hadn't intended and still don't intent to provide such service for anyone to use in real life. As it's prone to abuse and centralization.
But as my address was noticed and mistaken as potential new IPv6 fido member I clarified that it's not. ^_^

 KK>> There are two IPv6 prefixes:
 KK>>  - "f1d0 style" - 2a04:52c0:101:201:f1d0::/80
 KK>>  - "hex style" - 2a04:52c0:101:201:fed0::/80
 MvdV> I may test that hex option later.

Feel free while it lasts ^_^

Ganbatte, *Michiel*!
