IPv6 is finally here, available in the US location only for now.
All US Danbos, including existing ones, get a /64 subnet (that's 18446744073709551616 addresses per VM)
This also means that you can now use a VM without an IPv4 address, making the cheapest VM (at current prices) 1.7 EUR/mo.
If you bought a Danbo in the US before IPv6 was released (and used a cloud image to install):
~/.ssh/known_hosts
on your local machine.2a0f:85c1:356:beef::/64
, your VM is reachable at 2a0f:85c1:356:beef::1
