DNS (Domain Name System) records are entries that map domain names to IP addresses and other information. Common record types include:
A Record: Maps a domain to an IPv4 address.
AAAA Record: Maps a domain to an IPv6 address.
MX Record: Defines mail servers for email delivery.
CNAME Record: Points one domain to another.
TXT Record: Stores text data, often for verification or security (SPF, DKIM).
NS Record: Specifies authoritative name servers for the domain.
SOA Record: Contains administrative information about the domain.
