Instead , I expect to show something like one of the following:
http-listener-2 on host/port 127.0.0.1:8181
http-listener-2 on host/port localhost:8181
http-listener-2 on host/port [current machine IP]:8181
As 0.0.0.0 is an invalid IP address for communication,
Computers normally show an address of 0.0.0.0 when they are not connected to a TCP/IP network. Having this address, a computer cannot be reached or communicate with any other devices over IP.
TCP/IP software applications also use 0.0.0.0 as a programming technique to monitor network traffic from any valid IP address. While connected computers do not use this address, messages carried over IP sometimes include 0.0.0.0 inside the header when the source of the message is unknown.
And as I understand this is the network address listener for communication to the server via HTTP, HTTPS and admin console ports.
