Answer / Prashant Kumar Tripathi

"DNS records are used to map domain names to IP addresses and vice versa. Here's a brief description of the mentioned DNS records:nn- A Record (Address Record): Maps a domain name to its corresponding IPv4 address.n- NS Record (Name Server Record): Specifies the authoritative name servers for a given domain.n- PTR Record (Pointer Record): Used to map an IP address back to a hostname, specifically for IPv4 addresses.n- CNAME Record (Canonical Name Record): Alias for another domain name. Multiple CNAME records can exist for a single domain name, but only one A or MX record should be present.n- MX Record (Mail Exchange Record): Defines the mail servers responsible for handling email for a given domain."
