域名服务器的正确配置是提供优质鲁棒的网络服务的基础。大量工程实践表明,错误配置将严重影响网络应用。中国因特网是世界互联网的重要组成部分,发展日新月异,但管理水平参差不齐。该文采用多种实验方法对中国域名系统的配置状况进行了测量和分析。实验结果表明,.CN域中30%以上的区都存在配置问题,是中国互联网高效、安全运行的重大隐患,应引起足够重视。
The correct configuration of the nameservers is the foundation for providing good quality and robust network services. A large number of engineering practice shows that misconfiguration will seriously affect the network applications. The Internet in China is an important part of the Internet in the world. The development of the Internet is changing rapidly but the management level is uneven. This paper uses a variety of experimental methods to measure and analyze the configuration of China’s domain name system. The experimental results show that more than 30% of the regions in the .CN domain have configuration problems, which is a serious hidden danger of efficient and safe operation of the Internet in China and should be given enough attention.
