On-prem DNS - entries to be added

[Anonymous]

Hello,

I have a question about DNS addresses Databricks uses.

In our network configuration, we are using custom VNet injection with no public IPs, and are required to use on-premises corporate DNS.

Therefore we would like to add necessary entries to on-prem DNS - but are not sure which exactly addresses Databricks workspace uses.

Without explicit DNS configuration, clusters fails to start - with "Timeout placing nodes" error.

VMs are created in Azure, so obviously the issue is that head node cannot communicate with workers, as it's not able to resolve DNS.
