Huawei DNS Query – Explained
Avant d’obtenir un smartphone pliable, il faut absolument regarder les différents appareils disponibles sur le marché. Lequel, permettra vraiment de mater les blagues chaque jours de manière confortable ?
I feel that I need to explain what is Bei’an (备案) and why when you visit a Chinese website there will be DNS queries to [beian.gov.cn](https://beian.gov.cn), as it seems not many people know what it is.
Bei’an literally means « to put up a record », i.e. registration. In China, the government has strict control over Internet, and every website hosted in China has to be registered to the Ministry of Industry and Information Technology. In addition, if the website is an « Internet Content Provider », an additional license is required.
So, if you visit a website hosted in China, scroll down to the bottom and there is likely to be the registration number and ICP license number. For example, [http://www.google.cn/](http://www.google.cn/), which now only contains a redirection to [https://www.google.com.hk](https://www.google.com.hk), still has the following information: [ICP证合字B2-20070004号](http://www.miibeian.gov.cn/) which is Google’s (probably expired) ICP license number.
In the case of Baidu ([https://www.baidu.com/](https://www.baidu.com/)), it’s 京ICP证030173号 and [京公网安备11000002000001号](http://www.beian.gov.cn/portal/registerSystemInfo?recordcode=11000002000001). The first one is the ICP license number and the second one is the website hosting registration number. The later contains a link to [http://www.beian.gov.cn/portal/registerSystemInfo?recordcode=11000002000001](http://www.beian.gov.cn/portal/registerSystemInfo?recordcode=11000002000001) which is the official registration page of Baidu. And since most of the modern browsers have the « preloading » feature, it’s very likely the browser is trying to query [beian.gov.cn](https://beian.gov.cn) in advance to accelerate the speed if the user click the link later.
I believe this should explain why you will see DNS query to beian.gov.cn.
