Hello,
Please look into this document <https://cloud.google.com/appengine/docs/standard/python/appidentity/#getting_the_application_hostname>, which describes using the app_identity.get_default_version_hostname() method you can retrieve the entire hostname component if an app is served from a custom domain where the app ID is part of the hostname (i.e. http://<your_app_id>.appspot.com). So as George mentioned earlier you are getting expected behavior from the app_identity.get_default_version_hostname() method. Regarding your second question, if your domain is mapped to your App Engine app you can use the apps.domainMappings.list <https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1beta/apps.domainMappings/list> method to list your resource records. You can also achieve this using Console or gcloud command "gcloud app domain-mappings list" <https://cloud.google.com/sdk/gcloud/reference/app/domain-mappings/list>. You can get more details on this at number four point of this document <https://cloud.google.com/appengine/docs/standard/java/mapping-custom-domains#adding_a_custom_domain_for_your_application> and on gcloud command “gcloud app domain-mappings” here <https://cloud.google.com/sdk/gcloud/reference/app/domain-mappings/>. If your domain is not mapped, to programmatically map your domain to your App Engine app you can use the app.domainMappings.create <https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1beta/apps.domainMappings/create> method. You can find more about the methods available with REST Resource: apps.domainMappings here <https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1beta/apps.domainMappings#methods>.
