bind
bind overrides the host to which the server should bind.
Normally, the listener binds to the wildcard host. However, you may force the listener to bind to
another IP instead. This directive accepts only an address, not a port.
Syntax
bind ADDRESS
ADDRESS is the IP address to bind to.
Examples
To make your socket accessible only to that machine, bind to IP 127.0.0.1 (localhost):
bind 127.0.0.1
