Eliminating ISP Local DNS Exceptions

HTTPDNS replaces the default DNS method of mobile and desktop applications with the HTTP protocol, avoiding network access exceptions caused by the ISP's local DNS service errors.
It is mainly used in the development of the following types of mobile applications:

• News and game applications
  Applications that require a shorter access delay and less cross-network access and focus on fast response. Such applications connected to the service include Tencent Games and Autohome.
• Ecommerce applications
  Applications that require a lower connection failure rate and higher business efficiency and focus on the access request stability. Such applications connected to the service include Jumei and Ele.me.
• Social networking applications
  Applications with domains frequently hijacked that require smooth user access. Such applications connected to the service include Mobile QQ.
• Audio/Video applications
  Applications that demand a higher smoothness and connection success rate for music and video playback. Such applications connected to the service include Bilibili and QQ Music.
