The Authoritative Name Servers are the last and most important stop in the DNS Lookup your computer does when searching for a web page. They are responsible for logging and returning the DNS Zone (the sum of the different DNS Records) to the requesters.
The A Records, short for Address records, is arguably one of the most important DNS Records, as it tells the requester what’s the IP Address tied to the domain name – ergo, it provides the visitors the server location where your website content resides, so their browser can download and display it.
