About DNS Record Types
The Domain Name System (DNS) uses various record types to store different kinds of information about domains.
Common Record Types:
- A: Maps domain to IPv4 address
- AAAA: Maps domain to IPv6 address

- TXT: Stores text information (SPF, DKIM, etc.)
- CNAME: Creates domain aliases
- NS: Delegates domain to nameservers
Email-Related Records:
- MX: Mail server configuration
- TXT: SPF, DKIM, DMARC policies
- PTR: Reverse DNS for mail servers
- SRV: Service discovery for email
- CAA: Certificate authority authorization
