local address, either of those should work. That's the only address it has, or at least the only one it says it has. Automatic IPv6 address giving doesn't work, at least till Telefónica gives us IPv6 external addresses somehow. Any router capable of supporting IPv6 can provide addresses. Well, it doesn't.
It doesn't have a DHCPv6 server? Can't be configured for SLAAC?
I switched one machine here to automatic configuration - it is apparently impossible in YaST to have IPv4 manual configuration and IPv6 automatic configuration. Well, it got and IPv4 address, but not an IPv6:

There is nothing here to say whether it's a manual or some sort of automatic configuration. The fe80 link local shows IPv6 is supported, as does the ::1 loopback address. There is nothing magic here. In this regard, IPv6 is no different than IPv4, other than SLAAC can be used in addition to DHCP or manual configuration. If your router supports providing an IPv6 address via SLAAC or DHCPv6, that printer should have an IPv6 address. If you use either method, then other devices should also get IPv6 addresses. One thing to consider. Windows has something called HomeGroup networking, which requires IPv6 and uses the link local addresses. I assume the printer can work with it. If so, how is the configuration done?

I also tried:

If you think you have received this message due to a bug rather than a configuration issue please read the section on submitting bugs on either our web page at www.isc.org or in the README file before submitting a bug.
