ssh user@ipv6 address, connect: Network is unreachable

[basti <black.fledermaus@arcor.de>]

Hello,

I have a vps host which has only an ipv6 address.
I try ssh user@<ipv6_address> (or ssh -6 user@<ipv6_address>) but get
the following:

ssh: connect to host <ipv6_address> port 22: Network is unreachable

ping6 google.com is the same

connect: Network is unreachable

my config:

my ISP offers only ipv4, can this be the "error" ?
