Essential DNS Records Mastery

Learn to configure and manage all critical DNS records

A Record (Address Record)

Maps a domain name to an IPv4 address. The most fundamental DNS record.

example.com. 3600 IN A 192.0.2.1

CNAME Record (Canonical Name)

Creates an alias from one domain name to another. Points to another domain.

www.example.com. 3600 IN CNAME example.com

MX Record (Mail Exchange)

Directs email to mail servers. Specifies mail servers for a domain.

example.com. 3600 IN MX 10 mail.example.com

TXT Record (Text Record)

Stores text information. Used for SPF, DKIM, DMARC, and verification.

example.com. 3600 IN TXT "v=spf1 include:_spf.google.com ~all"

NS Record (Name Server)

Specifies authoritative name servers for a domain. Delegates DNS authority.

example.com. 86400 IN NS ns1.example.com

AAAA Record (IPv6 Address)

Maps a domain name to an IPv6 address. The IPv6 version of A record.

example.com. 3600 IN AAAA 2001:db8::1
