systemctl sudo unable to resolve host webserver

Name resolution is provided between virtual machines in virtual networks without need for the FQDN.

The name resolution service that Azure provides can be used along with your own DNS servers to resolve both on-premises and Azure hostnames.

You don't need to create and manage clusters of your own DNS servers.

The name resolution service that Azure provides is highly available.

No configuration is required to use name resolution that Azure provides.

Although the name resolution that Azure provides does not require any configuration, it is not the appropriate choice for all deployment scenarios, as seen on the preceding table. DNS names can be assigned to both network interface cards (NICs) and virtual machines. In virtual networks that are based on Azure Resource Manager, the DNS suffix is consistent across the virtual network the FQDN is not needed. Name resolution using your own DNS serverĪlong with resolution of public DNS names, Azure provides internal name resolution for virtual machines and role instances that are in the same virtual network. See Name resolution using your own DNS server. The proxy server forwards queries to Azure for resolution. Resolution of Azure hostnames from on-premises computersįorward queries to a customer-managed DNS proxy server in the corresponding virtual network. Resolution of on-premises computers and service names from role instances or virtual machines in AzureĬustomer-managed DNS servers (for example, on-premises domain controller, local read-only domain controller, or a DNS secondary synced by using zone transfers). Name resolution between role instances or virtual machines in different virtual networksĬustomer-managed DNS servers that forward queries between virtual networks for resolution by Azure (DNS proxy).

Hostname or fully-qualified domain name (FQDN) Name resolution between role instances or virtual machines in the same virtual network The following table illustrates scenarios and corresponding name resolution solutions: Scenario

The type of name resolution that you use depends on how your virtual machines and role instances need to communicate with each other. Name resolution using your own DNS server.The following scenarios should help you choose the one that works for your situation. You can implement your own DNS name resolution solution by configuring your own DNS services on your virtual machines that Azure hosts. Applies to: ✔️ Linux VMs ✔️ Flexible scale setsĪzure provides DNS name resolution by default for all virtual machines that are in a single virtual network.
