See [Azure services DNS zone configuration](../private-link/private-endpoint-dns.md#azure-services-dns-zone-configuration) for a list of domains that are reserved. The two-label DNS names listed in this article (for example: windows.net, azure.com, azure.net, windowsazure.us) are reserved for Azure services.
