Public recursive name server

A public recursive name server is like a directory that helps websites know where to find other websites on the Internet. It helps connect websites to other websites so you can find the information you are looking for. Think of it like a telephone book or a map. When you give the public recursive name server a website name, it looks it up and finds the address of the website and helps your browser find it on the Internet.
