Understanding DNS Records
DNS (Domain Name System) records are essential for the functioning of the internet. They map human-readable domain names to IP addresses and provide information about how to handle requests for those domains. Here are some common types of DNS records:
- SOA (Start of Authority): Contains administrative information about the domain, such as the primary name server and contact email.
- A (Address): Maps a domain name to an IPv4 address.
- AAAA: Maps a domain name to an IPv6 address.
- CNAME (Canonical Name): Alias for another domain name, allowing multiple domain names to point to the same IP address.
- MX (Mail Exchange): Specifies the mail servers responsible for receiving email for the domain.
- NS (Name Server): Indicates which name servers are authoritative for the domain.
- TXT (Text): Used to store arbitrary text data, often used for verification purposes or SPF records.
