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 hostname or IP instead. This directive accepts only a host, not a port.

For example, if two sites on the same port resolve to and only one of those sites is configured with bind, then only one site will be accessible since the other will bind to the port without a specific host; the OS will choose the more specific matching socket. (Virtual hosts are not shared across different listeners.)

To make your socket accessible only to that machine, bind to IP (localhost):
