     * to what the {@link io.netty.resolver.DefaultNameResolver} (JDK default) does. As we will need to open and close
     * a new socket for each resolution it will come with a performance overhead. That said using this strategy should
     * be the most robust and also guard against problems that can arise in kubernetes (or similar) setups.
