Use netstat to list listening ports on the box (netstat -ln) and see
if it shows up as tcp6 or tcp. On our (older) 17.11.8 server:
$ netstat -ln | grep :6817
tcp 0 0 0.0.0.0:6817 0.0.0.0:* LISTEN
$ nc -6 :: 6817
Ncat: Connection refused.
$ nc -4 localhost 6817
^C
netstat is obsolete, but ss shows the same results
