Trying to setup a node.js web server

I am new to web servers and node.js and I need some help.

I have no idea what to put in the .listen();

I think since I want it to connect to the internet the server needs to listen to port 80 but but I don't know what to put as the second value.

.listen(80, "What do I add here?");

Also i have a free domain name (www.example.co.cc) that is pointing to a dynamic dns (DnsExit) since I dynamic ip. I installed to program needed to update my ip开发者_运维知识库 address.

Is there anything I am missing?

Have you seen the example on the homepage of the Node.js project?

• http://nodejs.org/

It clearly demonstrated .listen( 1337, "127.0.0.1" ); and then the next line reads Server running at http://127.0.0.1:1337/ - so the second argument is the IP you want to listen on. If you then take a look at the documentation you will see that this second argument is actually optional, if you omit it, Node.js will accept incoming connections directed at any IPv4 address.
