Name resolution scenarios and options
DNS servers host records that translate human-readable domain names into machine-readable IP addresses (used by computers to communicate with each other). For example, Figure 2.7 shows the DNS server for the azurecourses.xyz domain zone, which has a single A record that translates the www.azurecourses.xyz hostname into the IP address 1.2.3.4. Clients that want to communicate with the web server called www.azurecourses.xyz can make a DNS request to their DNS resolver to translate the name into an IP address. The DNS resolver will then go through an iterative process to make a record request to the DNS server (Figure 2.7).

To facilitate network communications, there are two name resolution scenarios that we will cover:
- Internal name resolution: Providing name resolution for private/internal clients hosted in our virtual networks
- External name resolution:...
