What are the differences between IP address and

IP address, means all IP addresses on the local machine.


Let say we have a machine that has two IP addresses ( and and the apache web server runs on it. Now if we allow the apache webserver to listen on, it will be reachable at both of those IP addresses.

When a service is listening on this means the service is listening on all the configured network interfaces.

When listening on the service is only bound to the local machine.
