Azure DNS Server

Public zones, Private DNS zones, DNS Private Resolver and Azure-provided DNS — what each Azure DNS option does, why admins use it and how to set up a public zone step by step. This Azure Dns Server guide keeps it simple.

⚡ Short answer

DNS turns names like www.example.com into IP addresses. In Azure, “Azure DNS server” usually means one of four things: Azure DNS public zones (host your internet domains), Private DNS zones (names inside your VNets), DNS Private Resolver (connect Azure and on-premises DNS) and the built-in Azure-provided DNS every VNet gets.

Four options

Azure DNS options explained

🌍

1. Public DNS zones

Host records for your public domain on Microsoft’s global name servers

Manage A, AAAA, CNAME, MX, TXT and more

Alias records point to public IPs, Front Door or Traffic Manager

You still buy the domain from a registrar

🔒

2. Private DNS zones

Custom names inside your VNets, e.g. db.internal.contoso.com

Not exposed to the internet

Used for private endpoints, e.g. privatelink.blob.core.windows.net

🔁

3. DNS Private Resolver

On-premises servers resolve Azure private names

Azure resources resolve on-premises names

No DNS VMs to run

⚙️

4. Azure-provided DNS

Automatic for every VNet

Uses the special address 168.63.129.16

Switch to custom DNS servers if needed

Best practices for Azure DNS

✅ ✅ Checklist: Put resource locks on production zones • use private zones for internal names and private endpoints • keep DNS records in code • use the Private Resolver for hybrid networks instead of custom DNS VMs.
