What is Azure Private DNS?

Azure Private DNS is a DNS service for Azure virtual networks. You can register a private DNS zone to Azure Private DNS and then link that zone with one or more virtual networks. If you enable DNS auto-registration for a virtual network, a new resource (e.g. virtual machines and VPN Gateways) will automatically add its IP address to Azure Private DNS. Resources in the linked virtual networks can use entries in Azure Private DNS to locate each other, instead of relying on IP addresses or the default Azure DNS domain. You can make Azure Private DNS and Azure VPN Gateway work together in several ways, some of which this article will describe.

Computers were supposed to relieve us humans from boring and repetitive jobs.
