vazhnov, Some days ago I found an advertisement of #Finemedia ISP in my postbox (in #Wrocław, #Poland). As usual, I sent an email with a question about #IPv6 support (I use Orange, but I'm interesting to have alternative).
Surprisingly, the answered was they can provide an IPv6 /56 network per router.
But I don't see any documentation about it. I see they own 2a02:21a0::/29, but that doesn't mean they use it.
Maybe the Fediverse knows something about Finemedia's IPv6 support for end users?
