Your domain's DNS zone is made up of individual records, each with a specific job. Here are the ones you'll run into most.
A Record
Points a domain or subdomain directly to a numeric IP address. This is the core record that tells the internet where your website actually lives.
CNAME Record
Points a subdomain to another domain name instead of an IP address — useful for pointing something like shop.yourdomain.com to a third-party service without needing to know its IP address.
MX Record
Directs email for your domain to the correct mail server. If your MX records are misconfigured, email sent to your domain simply won't arrive.
TXT Record
Stores arbitrary text data, most commonly used for domain verification (proving you own a domain to a third-party service) and email authentication records like SPF, DKIM, and DMARC.
NS Record
Specifies which nameservers are authoritative for your domain — essentially, which company's DNS system is in charge of the rest of your records.
Making Changes Safely
Always double-check a record's exact value before saving, and remember that changes take time to propagate — avoid making multiple conflicting changes in quick succession.
