accessing the Internet services and Web sites can be in a number of different links dynamic allocation and load balancing, which is also known as outbound traffic load balance.
External users of the Internet can also dynamically balance the distribution on multiple links while accessing internal Web sites and application systems externally. And can automatically switch to another link to the server and application system when a link is interrupted,
Because of a sudden evil idea, I want to build a DNS server on my Android tablet, because I have sl4a and Python's interpreter installed on the tablet before, and I want to continue to learn python, so I intend to implement it in Python.
Looking at Google, the Python implementation of DNS, did not find the answer I wanted, so I decided to implement it.

This article is about configuring and managing DNS servers.
First understand the role of the DNS service, when to use? How do you use it?
In the current network, the computer through the IP address to communicate, IP address with digital, memory is too difficult, for the computer A good name, everything is easy.

When we enter the domain name Chaoyang. Beijing. China in the browser, the browser will translate the Chinese domain name into Punycode code and then
It is transferred to the DNS server for resolution, for example, after being translated into Punycode by Chaoyang. Beijing. China
Xn -- tpv1_h. xn -- 1lq90i. xn -- fiqs8s
Chaoyang = xn -- tpv
