DNS Records Cheat-Sheet for Quick Domain Setup

Managing DNS can feel tricky, but having a solid reference guide makes it way easier. The DNS Records Cheat-Sheet is your go-to resource for understanding every essential DNS record type and how it impacts your website or service performance.

Key DNS Record Types Explained ​

A Record (Address Record)​

Maps your domain name to an IP address (IPv4).
Example: example.com → 192.168.1.1
This is the most basic DNS record and is essential for directing visitors to your website.

AAAA Record​

Similar to the A record, but it maps to an IPv6 address, supporting modern internet connectivity.

CNAME Record (Canonical Name)​

Creates an alias for a domain name.
Example: www.example.com → example.com
Perfect for redirecting multiple domains to one main domain.

MX Record (Mail Exchange) ​

Directs emails to your mail server.
Example: example.com → mail.example.com
Essential for configuring business email services like Google Workspace or Microsoft 365.

TXT Record​

Stores text-based information, often for security and authentication.
Common uses include:

• SPF (Sender Policy Framework) to prevent email spoofing.
• DKIM for verifying email integrity.
• DMARC for email authentication and policy enforcement.

NS Record (Name Server)​

Specifies which servers handle your domain’s DNS.
Example: example.com → ns1.hosting.com, ns2.hosting.com
