This is inspired by the answer by Bruce Forte. That answer only works with IPv4 which means it doesn't work for me. I have rewritten it into a version that (only) works with IPv6:
ip r g b::|awk '$0=$9" "$9'
This is tested on Ubuntu 14.04.5 connected through PPPoE and since IPv6 is designed to be used without any NAT it will output the same IP address twice.
