addr

Get the remote address of a request, with reverse-proxy support

Usage

$ npm install addr

addr(req, [proxies])

• req: an http.ServerRequest object.
• proxes: an array of IP addresses of trusted proxies. If specified and the request doesn't come from one of these addresses, the X-Forwarded-For header will not be honored.
• Returns: Remote IP address of the request, taken from the X-Forwarded-For header if it exists and the request is coming from a trusted proxy.

Example

var addr = require('addr')
  , http = require('http')
  , port = 3000
  , proxies = ['127.0.0.1']
  ;

http.createServer(function(req, res) {
  res.writeHead(200, {'Content-Type': 'application/json'});
  res.write(JSON.stringify({addr: addr(req, proxies)}));
  res.end();
}).listen(port, function() {
  console.log('test server running on port ' + port);
});
