Where does the alias point?
Enter a subdomain (like www) to see the target its CNAME record points to.
About this tool
A CNAME record links one name as an "alias" to another name. For example www.example.com can point via CNAME to example.com so both are managed together. CNAMEs are widely used to connect a domain to a CDN, email service or cloud platform.
Frequently asked questions
What is a CNAME record?
A record that points one hostname as an alias to another canonical name.
CNAME vs A record?
An A record points to an IP; a CNAME points to another hostname and needs no update when the IP changes.
Why can't the root domain use CNAME?
By standard, the root (no www) can't have a CNAME; use an A or ALIAS record instead.
