- A (Address) Record
- Maps a domain name to the IPv4 address of the computer hosting the domain. It is the most common record type and is essential for a website to be reachable.
- MX (Mail Exchange) Record
- Specifies the mail servers responsible for accepting email messages on behalf of a domain name. Multiple MX records can exist with different priority levels.
- NS (Name Server) Record
- Delegates a domain or subdomain to a set of authoritative name servers. These are the servers that store all the DNS records for the domain.
- TXT (Text) Record
- Allows an administrator to store arbitrary text in the DNS. It's commonly used for email security (SPF, DMARC) and domain ownership verification.
- CNAME (Canonical Name) Record
- Creates an alias, pointing one domain name to another. The aliased domain gets all the records of the original, canonical domain.
- SOA (Start of Authority) Record
- Contains administrative information about the domain, such as the primary name server, the email of the domain administrator, and timing settings.
- DMARC Record
- An email authentication protocol that helps protect against phishing and spoofing. It tells receiving mail servers what to do with messages that fail authentication checks.
- SPF (Sender Policy Framework) Record
- A type of TXT record that lists all the servers authorized to send email on behalf of a domain. It helps prevent spammers from spoofing your domain.
- Reverse DNS (PTR Record)
- Maps an IP address back to a domain name, which is the opposite of an A record. It's often used as a security measure to verify the identity of a server.
