# CNAME

CNAME or canonical name in Scaleflex DMO is used to replace your-token.cloudimg.io with your own domain name.

Example: //your-token.cloudimg.io/original\_image\_url/image.jpg to be replaced by\
//your-own-domain-name.com/original\_image\_url/image.jpg

Add one or multiple custom domains to deliver DAM assets over your subdomains, for example medias.acme.com. Once the custom domain added, you will need to create 2 DNS CNAME entries to validate the TLS certificate and point your subdomain to Scaleflex DMO.

Example:

* DNS1: \_076f48ef8df3a3ca368b89c6f0bb0bcf.medias.acme.com. CNAME \_29163927834ee4c4e03c365fd7282c74.nhqijqisfx.acm-validations.cdnprovider
* DNS2: medias.acme.com CNAME token.cdnprovider.com
