About DNS Records
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
