DNS Server Configuration on the Azure Virtual Network
For hostname resolution, the Amazon Web Services (AWS) appliance requires you to configure a DNS server in the Virtual Private Cloud (VPC).
For hostname resolution, the Azure appliance requires you to configure a DNS server in the virtual network or use the DNS server provided by Azure. Any on-premises Authentication Manager primary instance or replica instances must use the DNS server that is configured in the virtual network.
