Expert knowledge for Azure DNS development including troubleshooting, decision making, architecture & design patterns, limits & quotas, security, configuration, and integrations & coding patterns. Use when automating DNS zones/records, configuring Private DNS/resolvers, enabling DNSSEC, or migrating legacy zones, and other Azure DNS related development tasks. Not for Azure Traffic Manager (use azure-traffic-manager), Azure Front Door (use azure-front-door), Azure Virtual Network (use azure-virtual-network), Azure Application Gateway (use azure-application-gateway).
This skill provides expert guidance for Azure DNS. Covers troubleshooting, decision making, architecture & design patterns, limits & quotas, security, configuration, and integrations & coding patterns. It combines local quick-reference content with remote documentation fetching capabilities.
How to Use This Skill
IMPORTANT for Agent: Use the Category Index below to locate relevant sections. For categories with line ranges (e.g., L35-L120), use read_file with the specified lines. For categories with file links (e.g., [security.md](security.md)), use read_file on the linked reference file
IMPORTANT for Agent: If metadata.generated_at is more than 3 months old, suggest the user pull the latest version from the repository. If mcp_microsoftdocs tools are not available, suggest the user install it: Installation Guide
This skill requires network access to fetch documentation content:
Preferred: Use mcp_microsoftdocs:microsoft_docs_fetch with query string from=learn-agent-skill. Returns Markdown.
Fallback: Use fetch_webpage with query string from=learn-agent-skill&accept=text/markdown. Returns Markdown.

Description
Troubleshooting
L35-L39
Diagnosing and resolving Azure DNS name resolution failures, including troubleshooting DNS records, zones, forwarding, and common configuration or connectivity issues.
Decision Making
L40-L44
Guidance for planning and executing migration of legacy Azure Private DNS zones to the new DNS zone model, including compatibility, steps, and considerations.
Architecture & Design Patterns
L45-L50
Designing resilient private DNS architectures in Azure, including when to use centralized vs distributed DNS Private Resolvers and how to shard Private DNS zones for high availability.
Limits & Quotas
L51-L55
DNS record, zone, and query limits for Azure DNS and Private DNS, including quotas, scaling behaviors, usage constraints, and how many zones/records you can create and manage.
Security
L56-L66
Securing Azure DNS and Private DNS: access control, monitoring, DNSSEC (enable/remove), resolver policies, and threat protection for zones, records, and name resolution.
Configuration
L67-L79
Configuring Azure DNS behavior: reverse DNS, private DNS zones and resolvers, zone file import/export, monitoring/metrics/logs, and query/ResolutionPolicy settings for name resolution.
Integrations & Coding Patterns
L80-L88
Automating Azure DNS zone/record management and subdomain delegation with PowerShell/CLI, plus importing/exporting DNS zone files and mapping Azure services to DNS record types.
