 This quickstart walks you through the steps to create your first private DNS zone and record using the Azure CLI.
 
-A DNS zone is used to host the DNS records for a particular domain. To start hosting your domain in Azure DNS, you need to create a DNS zone for that domain name. Each DNS record for your domain is then created inside this DNS zone. To publish a private DNS zone to your virtual network, you specify the list of virtual networks that are allowed to resolve records within the zone.  These are called *linked* virtual networks. When autoregistration is enabled, Azure DNS also updates the zone records whenever a virtual machine is created, changes its' IP address, or is deleted.
