Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you have delegated your custom domain to Azure DNS and you are now trying to Map the custom domain to an Azure Blob Storage endpoint/Static website.
You can follow the steps mentioned in this document.
However, please be aware that only HTTP is supported with custom domain.
If your requirement is to use HTTPS, you should consider using Azure CDN along with storage account.
- See : Integrate an Azure storage account with Azure CDN.
- Then map the customdomain to the CDN : Map Azure CDN content to a custom domain.
- And then Enable HTTPS on an Azure CDN custom domain.
P.S :
- I am not sure about the restriction placed by your registrar
- Technically speaking, since you have delegated the domain to Azure - Azure DNS supports TXT and CNAME records.
Kindly let us know if this helps or you need further assistance on this issue.
Thanks,
Kapil
