Can I listen to website url host? Node JS

I can't understand one thing- does NodeJS allow to listen to custom hostname? Not localhost. Because when I listen to my website url (example.com), I'm getting the following error:

Error: listen EADDRNOTAVAIL example.com ip-address:1000 at Object.exports._errnoException (util.js:1022:11) at exports._exceptionWithHostPort (util.js:1045:20) at Server._listen2 (net.js:1246:19) at listen (net.js:1295:10) at net.js:1405:9 at _combinedTickCallback (internal/process/next_tick.js:77:11) at process._tickCallback (internal/process/next_tick.js:98:9) at Module.runMain (module.js:606:11) at run (bootstrap_node.js:394:7) at startup (bootstrap_node.js:149:9)

Why does it happend? And can I listen for POST messages from external site URL?

Why does it happend?

This happens because the hostname and port you requested isn't available to you.

can I listen for POST messages from external site URL?

No, You can't. server.listen() accepts hostname and port

Begin accepting connections on the specified port and hostname. If the hostname is omitted, the server will accept connections on any IPv6 address (::) when IPv6 is available, or any IPv4 address (0.0.0.0) otherwise. Omit the port argument, or use a port value of 0, to have the operating system assign a random port, which can be retrieved by using server.address().port after the 'listening' event has been emitted.

And further digging into list of Node.js Common System Errors docs and exhaustive list, It is clear that, Address not available was the case.

EADDRNOTAVAIL Address not available (POSIX.1).
