DNS (Domain Name System) records control how your domain directs traffic. Understanding DNS records allows you to manage email delivery, website access, third-party integrations, and more.
Accessing DNS Management
1. Log in to your control panel.
2. Navigate to "DNS Zone Editor" or "DNS Management."
3. Select the domain you want to manage.
Common DNS Record Types
A Record: Points a domain or subdomain to an IPv4 address. This is the primary record that tells browsers where to find your website.
Example: yourdomain.com -> 203.0.113.10
AAAA Record: Points a domain or subdomain to an IPv6 address. Works the same as an A record but for the newer IPv6 protocol.
Example: yourdomain.com -> 2001:db8::1
CNAME Record: Creates an alias from one domain name to another. Cannot be used on the root domain (use A record instead).
Example: www.yourdomain.com -> yourdomain.com
MX Record: Specifies the mail server responsible for receiving email for your domain. The priority number determines which server is tried first (lower number = higher priority).
Example: yourdomain.com -> mail.yourdomain.com (priority 10)
TXT Record: Stores text data for various purposes including email authentication (SPF, DKIM, DMARC) and domain verification for third-party services.
Example: yourdomain.com -> "v=spf1 include:_spf.google.com ~all"
SRV Record: Specifies the location of services like SIP, XMPP, or Microsoft 365.
Common Use Cases
Email Setup: Add MX records to route email to your mail provider. Add SPF, DKIM, and DMARC TXT records for email authentication.
CDN Setup: Create a CNAME record pointing your domain or subdomain to your CDN provider's hostname.
Domain Verification: Add a TXT record with a verification code provided by services like Google Workspace, Microsoft 365, or SSL providers.
Tips
- Changes to DNS records can take up to 24-48 hours to propagate globally.
- Always double-check record values before saving, as incorrect DNS can take your site offline.
- Lower TTL values before making changes so updates propagate faster.
- Keep a record of your DNS settings for reference.
