Domain CNAME Checker
Check CNAME records associated with a domain.
How to Use Domain CNAME Checker
Enter a subdomain or domain name (e.g., www.example.com or shop.example.com) in the search box.
Click the 'Find CNAME Records' button.
View the canonical target hostname that this domain is pointing to.
Why Use This Tool?
Verify Platform Integration
Check if your domain is successfully pointing to third-party platforms like Shopify, Squarespace, or Vercel.
Debug Email Subdomains
Verify if your email marketing platforms (like SendGrid or Mailchimp) have successfully verified your CNAME bounces.
Check WWW Redirects
Ensure your 'www' subdomain is properly aliased to your root domain.
Understanding Your Results
Canonical Name (CNAME)
A type of DNS record that maps an alias name to a true or canonical domain name.
Root Domain Rule
Standard DNS rules dictate that you cannot put a CNAME record on a root domain (e.g., example.com). They are almost exclusively used on subdomains (e.g., www.example.com).
Redirection
CNAMEs are resolved by the browser looking up the target's IP address and connecting there instead.
