Introduction

A CNAME record allows a subdomain to work as an alias of another domain name. It is commonly used to connect external services, web platforms or the www version of a site.

For example:

blog.mydomain.com -> externalservice.com

When to use a CNAME

You can use it to:

  • Point www to another domain.
  • Connect a subdomain with an external platform.
  • Configure email, marketing or verification tools that require a DNS alias.

Steps to create the record

  1. Log in to the panel that manages the DNS zone.
  2. Open the zone editor.
  3. Select the correct domain.
  4. Choose CNAME as the record type.
  5. In Host or Name, enter the subdomain, for example blog.
  6. In Target, enter the destination name, for example externalservice.com.
  7. Save the change and wait for propagation.

Conclusion

Setting up a CNAME is a simple way to connect a subdomain with another service. The important part is creating the record in the right DNS zone and avoiding conflicts with other records that use the same name.
