Whenever you surf the Internet, you need to use the Domain Name System (DNS). When you want to browse a website, you usually enter the domain name of the website in the address bar of the browser, and then the computer will send this domain name to the DNS for resolution, and return the corresponding server IP address. The browser then knows which server to connect to for HTTP data.

For so many years, we've been so used to using DNS provided by ISPs that we've almost forgotten it exists. Most Internet users have the automatic DNS Settings on their computers.

But imagine what would happen if an ISP manually interfered with the DNS resolution results? Bad resolution, DNS hijacking... You're probably familiar with the whole 114 web navigation thing, right? When you hit a wrong key, you are often taken to a "web navigation" site filled with advertisements. Be tempted to generate click value.

Google is powerful. He likes to play with everything. Of course, it also has good resources in its hands, only dare to take it out to play. Google has enabled two great IP addresses for public DNS services.

I believe that many friends in order not to be hijacked, have already started to use OpenDNS public DNS service. Google Public DNS is a similar service. The IP addresses of the two DNS servers are 8.8.8.8 and 8.8.4.4. Easy to remember, isn't it? Can you manually set your DNS to these two IP addresses and try again will it still get hijacked?

Although Google's public DNS works well, it inevitably faces a problem that foreign websites also face: powerful Qiang. This non-question will not be discussed. Enthusiastic netizens can guess, Google launched the open DNS service for what purpose? Please leave your comments in the comments section.
