Recursive DNS server: What does it mean?
In computers, recursion refers to a technique for addressing a problem. That calls for an answer or a strategy that will keep repeating itself until it achieves its objective. So, the Recursive DNS server is in charge of looking up the information required to respond to DNS requests made by users.
Recursive DNS servers serve as a bridge between end users and authoritative DNS servers. A recursive DNS server will look up the IP address whenever a domain name is entered. This server returns to the browser on the requested device after determining the precise IP address for the requested domain name. By connecting to that IP address, the device is finally able to access the required website, and the website is loaded.
