Common DNS Terms and Definitions
A Record
Points your domain or subdomain to an IP address (the “street address” of your website).
Example:
yourstudio.com → 104.26.3.2
CNAME Record
Points a subdomain (like www) to another domain name instead of an IP address.
Example:
www.yourstudio.com → yourstudio.com
MX Record (Mail Exchange)
Tells the internet where to deliver email sent to your domain.
Example:
If you use PhotoBiz Mailbox, your MX records point to Rackspace mail servers.
TXT Record
Stores plain text used for verification or email authentication (SPF, DKIM, DMARC).
Examples:
-
Verifying your domain with Google
-
Connecting to Facebook Business
-
SPF record for email reputation
Nameservers
Nameservers control where your DNS is managed.
Examples:
-
If your nameservers point to PhotoBiz AWS, you manage DNS inside your PhotoBiz account.
-
If your nameservers point to GoDaddy, DNS updates must be made at GoDaddy.
TTL (Time To Live)
Tells how long DNS records are cached before the internet checks for updates again.
Example:
A TTL of 3600 = changes may take up to 1 hour to fully update.
