How can you forget these IP addresses: "8.8.8.8" and "8.8.4.4"?

 Primary DNS: 8.8.8.8 
 Secondary DNS: 8.8.4.4 

How can you forget the following IP addresses: "8.8.8.8" and "8.8.4.4"?

It is Google's public DNS resolvers.


I could make use of them for the following tasks:

• Use as the DNS resolvers on my PCs, Servers, Routers, and Switches
• As an example when I explain DNS configuration in the training courses.
• As a tool to verify global DNS resolution result of my own domain, especially when I changed my domain records.

Great! And it is from Google!
