Hello @Tom@gematrix ,
You can use alias records to point your DNS zone apex to Azure CDN endpoints. This is useful when you create static websites using Azure storage and Azure CDN. You can then access the website without prepending "www" to your DNS name.
CNAME records aren't supported at the zone apex. So, you can’t use a CNAME record to point your apex domain to your CDN endpoint. Instead, you can use an alias record to point the zone apex to a CDN endpoint directly.
Please refer: https://learn.microsoft.com/en-us/azure/dns/dns-alias#point-zone-apex-to-azure-cdn-endpoints
https://learn.microsoft.com/en-us/azure/dns/tutorial-alias-tm
Also, if you require HTTPS access for your web content, then after mapping your Azure CDN content to a custom domain, you have to enable HTTPS on your Azure CDN custom domain.
Kindly let us know if the above helps or you need further assistance on this issue.
