How does it know the router address if there is no route ?
Maybe the output of the following command is more complete :

ip -4 route show table all

Is the IPv4 configuration static or dynamic (DHCP) ?

A bit hard to read. "ip -6 route show" would be easier to read. Anyway 
it looks like it contains the usual IPv6 routes (subnet prefix, 
link-local prefix, local addresses, default route with router).
