DNS (Domain Name System) records are instructions that provide information about a domain, including its IP addresses, mail servers, and other services. Common record types include:

• SOA (Start of Authority) - Contains administrative information about the zone
• NS (Nameserver) - Specifies authoritative nameservers for the domain
• A (Address) - Maps a domain to an IPv4 address
• AAAA - Maps a domain to an IPv6 address
• CNAME (Canonical Name) - Creates an alias pointing to another domain
• MX (Mail Exchange) - Specifies mail servers for the domain
