 # What is a private Azure DNS zone
 
 Azure Private DNS provides a reliable, secure DNS service to manage and resolve domain names in a virtual network without the need to add a custom DNS solution. By using private DNS zones, you can use your own custom domain names rather than the Azure-provided names available today. 
 
-The records contained in a private DNS zone are not resolvable from the Internet. DNS resolution against a private DNS zone works only from virtual networks that are linked to it.

 You can link a private DNS zone to one or more virtual networks by creating [virtual network links](./private-dns-virtual-network-links.md).
-You can also enable [auto-registration](./private-dns-autoregistration.md) feature to automatically manage the life cycle of the DNS records for the virtual machines deployed in a virtual network.

 ## Limits
 
-To understand how many private DNS zones you can create in a subscription and how many record sets are supported in a private DNS zone see [Azure DNS limits](../azure-resource-manager/management/azure-subscription-service-limits.md#azure-dns-limits)

 ## Restrictions
 
-* Single labeled private DNS zones are not supported. Your private DNS zone must have two or more labels. For example contoso.com has two labels separated by a dot. A private DNS zone can have a maximum 34 labels.
-* You can't create zone delegations (NS records) in a private DNS zone. If you intend to use a child domain, you can directly create the domain as a private DNS zone and link it to virtual network without setting up a nameserver delegation from the parent zone.
