Introduction
As an Azure network support engineer, you are responsible for ensuring that computers and devices on your network stay connected. Name resolution is the process of matching the name of a computer to its network address. If a name cannot be resolved, the computer will not be visible on the network, causing a breakdown in connectivity. Name resolution may be:
Public, using public Domain Name System (DNS) servers.
Internal to Azure, using Azure infrastructure.
On-premises, using your own DNS server.
You might also adopt a hybrid approach, using a combination of either private and public DNS, or on-premises and Azure DNS servers.
In this unit you will learn how to troubleshoot internal Azure name resolution issues and public DNS issues.
