Can you see if it is listening on 9200 on the non localhost address?

I have the line 

  network.host: 10.0.0.1

in my config that binds it to that specific IP address and I have lines
like 

java    48111 elasticsearch  382u  IPv6 1550135      0t0  TCP 10.0.0.1:vrace (LISTEN)
java    48111 elasticsearch  530u  IPv6 1608995      0t0  TCP 10.0.0.1:wap-wsp (LISTEN)

in the lsof output.
