CoreAzure DNS
Azure-hosted public and private DNS zones and records.
Key points
- Hosts authoritative public DNS zones and Azure-linked private DNS zones.
- Record sets map names to values while public delegation points a domain to Azure name servers.
- Private zone links determine which VNets can resolve private records.
Best-known use cases
- Host public records for an application domain.
- Resolve a private endpoint name inside selected VNets.
What candidates often confuse it with
- Public vs private DNS zone: internet-authoritative records vs VNet-scoped private resolution.
- Azure DNS vs Load Balancer: name resolution vs traffic distribution.
Key takeaway
Use Azure DNS to host the appropriate public or private records and verify delegation or VNet links before troubleshooting traffic.
