Excellent software and practical tutorials
DNS The server is usually funded by Internet Service Providers (ISP), such as Telecom/Mobile Broadband, which have established multiple groups of DNS servers across the country. When you dial up to the Internet, it will automatically be assigned to you by region. Generally, you can surf the Internet normally without paying attention to it. But the problem is that the DNS provided in some areas often crashes, is overcrowded and has not been expanded in time, and is slow to resolve during peak Internet access. In some places, the computer room staff even abuse their power for personal gain, use DNS to hijack websites, secretly insert advertisements/induce/sniff account passwords, etc., which will affect the user's Internet speed, Internet experience and account security.
If your Internet access is unstable, try changing to a faster, more stable, cleaner, safer, and non-hijacked DNS, which may solve the problem! Fortunately, in addition to the DNS of broadband providers, some large Internet companies with sufficient strength, such as Alibaba Cloud, Tencent Cloud, Google, Baidu, IBM, CNNIC, etc., are also very generous to provide free DNS resolution servers to the public. Yidiyuan has collected a list of these reliable, free and high-speed public DNS server addresses around the world for everyone to choose.
The following are the IP addresses of relatively reliable free public DNS services in the world (mostly in China). Due to regional differences, the performance of the same set of DNS servers in different countries and regions is not exactly the same, and the resolution speed, response time, etc. are also different, so it is recommended that you use your own speed test results as the standard.

The free global public DNS service provided by Google is mainly used to improve the browsing speed and browsing experience of Internet users. There is basically no need to introduce it. It is probably the most widely used public DNS in the world. It is old, stable and technologically powerful.
