 Azure Private DNS provides a reliable and secure DNS service for your virtual network. Azure Private DNS manages and resolves domain names in the virtual network without the need to configure a custom DNS solution. By using private DNS zones, you can use your own custom domain name instead of the Azure-provided names during deployment. Using a custom domain name helps you tailor your virtual network architecture to best suit your organization's needs. It provides a naming resolution for virtual machines (VMs) within a virtual network and connected virtual networks. Additionally, you can configure zones names with a split-horizon view, which allows a private and a public DNS zone to share the name.
 
-To resolve the records of a private DNS zone from your virtual network, you must link the virtual network with the zone. Linked virtual networks have full access and can resolve all DNS records published in the private zone. You can also enable autoregistration on a virtual network link. When you enable autoregistration on a virtual network link, the DNS records for the virtual machines in that virtual network are registered in the private zone. When autoregistration gets enabled, Azure DNS also updates the zone records whenever a virtual machine gets created, changes its' IP address, or gets deleted.

 Azure DNS provides the following capabilities:
 
-* **Automatic registration of virtual machines from a virtual network that's linked to a private zone with autoregistration enabled**. The virtual machines are registered (added) to the private zone as A records pointing to their private IP addresses. When a virtual machine in a virtual network link with autoregistration enabled gets deleted, Azure DNS also automatically removes the corresponding DNS record from the linked private zone.

When a virtual machine in a virtual network link with autoregistration enabled gets deleted, Azure DNS also automatically removes the corresponding DNS record from the linked private zone.
 
 * **Forward DNS resolution is supported across virtual networks that are linked to the private zone**. For cross-virtual network DNS resolution, there's no explicit dependency such that the virtual networks are peered with each other. However, you might want to peer virtual networks for other scenarios (for example, HTTP traffic).
 
-* **Reverse DNS lookup is supported within the virtual-network scope**. Reverse DNS lookup for a private IP within the virtual network assigned to a private zone returns the FQDN that includes the host/record name and the zone name as the suffix.

 ## Other considerations
 
 Azure DNS has the following limitations:
 
 * A specific virtual network can be linked to only one private zone if automatic registration of VM DNS records is enabled. You can however link multiple virtual networks to a single DNS zone.
 * Reverse DNS works only for private IP space in the linked virtual network
-* Reverse DNS for a private IP address for a linked virtual network returns *internal.cloudapp.net* as the default suffix for the virtual machine. For virtual networks that are linked to a private zone with autoregistration enabled, reverse DNS for a private IP address  returns two FQDNs: one with default the suffix *internal.cloudapp.net* and another with the private zone suffix.
+* Reverse DNS for a private IP address in linked virtual network will return `internal.cloudapp.net` as the default suffix for the virtual machine. For virtual networks that are linked to a private zone with autoregistration enabled, reverse DNS for a private IP address  returns two FQDNs: one with default the suffix `internal.cloudapp.net` and another with the private zone suffix.
 * Conditional forwarding isn't currently natively supported. To enable resolution between Azure and on-premises networks, see [Name resolution for VMs and role instances](../virtual-network/virtual-networks-name-resolution-for-vms-and-role-instances.md).
