Detailed explanation-1: -DNS, or the Domain Name System, translates human readable domain names (for example, www.amazon.com) to machine readable IP addresses (for example, 192.0.2.44).

Detailed explanation-2: -To check a specific DNS record, you need to specify the nslookup command, an optional record type (for example, A, MX, or TXT ), and the host name that you want to check. Note: If you omit the record type, it defaults to A . The first two lines of output specify the server to which the request was directed.

Detailed explanation-3: -A DNS record is a database record used to map a URL to an IP address. DNS records are stored in DNS servers and work to help users connect their websites to the outside world. When the URL is entered and searched in the browser, that URL is forwarded to the DNS servers and then directed to the specific Web server.
