@WebServlet(urlPatterns = {"/GetRemoteHost"})
public class GetRemoteHost extends HttpServlet {
    @Override
    public void doGet(HttpServletRequest req, HttpServletResponse res)throws ServletException, IOException{
        try(PrintWriter out = res.getWriter()){
            String remoteHost = req.getRemoteHost();
            out.println("<html><head><title>Client Details</title></head>");
            out.println("<body><h1>" + remoteHost);
            out.println("</h1></body></html>");
