## Listen

Syntax: Listen [IP address:]port number
Context: server config
Status: core
Compatibility: Listen is only available in Apache 1.1 and later.

The Listen directive instructs Apache to listen to more than one IP address or port; by default it responds to requests on all IP interfaces, but only on the port given by the `Port` directive.

`Listen` can be used instead of `BindAddress` and `Port`. It tells the server to accept incoming requests on the specified port or address-and-port combination. If the first format is used, with a port number only, the server listens to the given port on all interfaces, instead of the port given by the `Port` directive. If an IP address is given as well as a port, the server will listen on the given port and interface.

Note that you may still require a `Port` directive so that URLs that Apache generates that point to your server still work.

Multiple Listen directives may be used to specify a number of addresses and ports to listen to. The server will respond to requests from any of the listed addresses and ports.

For example, to make the server accept connections on both port 80 and port 8000, use:

       Listen 80
       Listen 8000

To make the server accept connections on two specified interfaces and port numbers, use

       Listen 192.170.2.1:80
       Listen 192.170.2.5:8000
