I am trying to retrieve the IP address which makes the call to a REST call.

The code I have is:

import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.*;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;

import org.json.JSONObject;

@Path("/api")
public class Endpoints {

    @GET
    @Path("/whoami")
    @Produces(MediaType.APPLICATION_JSON)
    public String testHeaders(@Context final HttpServletRequest request){

        final JSONObject json = new JSONObject();
        json.put("remoteaddr", request.getRemoteAddr());

        return json.toString(4);
    }

}

the application is deployed on heroku here. When you make the call to the api it returns the ip is: 10.155.0.152, how ever when I google it it says my IP address is something different. Is there any way to return the actual IP?
