How to get the user IP address in Meteor server?

Question

I would like to get the user IP address in my meteor application, on the server side, so that I can log the IP address with a bunch of things (for example: non-registered us

You have to hook into the server sessions and grab the ip of the current user:

Meteor.userIP = function(uid) {
      var k, ret, s, ss, _ref, _ref1, _ref2, _ref3;
      ret = {};
      if (uid != null) {
            _ref = Meteor.default_server.sessions;
            for (k in _ref) {
                  ss = _ref[k];
                  if (ss.userId === uid) {
                        s = ss;
                  }
            }
            if (s) {
                  ret.forwardedFor = ( _ref1 = s.socket) != null ? 
                        ( _ref2 = _ref1.headers) != null ? 
                        _ref2['x-forwarded-for'] : void 0 : void 0;
                  ret.remoteAddress = ( _ref3 = s.socket) != null ? 
                        _ref3.remoteAddress : void 0;
            }
      }
      return ret.forwardedFor ? ret.forwardedFor : ret.remoteAddress;
};

Of course you will need the current user to be logged in. If you need it for anonymous users as well follow this post I wrote.

P.S. I know it's an old thread but it lacked a full answer or had code that no longer works.
