You do get a fully qualified domain name (FQDN) but it is under an azure owned domain. Here is the naming convention:
{domainname}.{region}.azurecontainer.io

The domain name label is provided with the service (line 6). The region is controlled by the resource group under which your docker ACI context is setup.

To get your container mapped to your custom domain you can setup a CNAME record pointing at The Azure FQDN.
