Azure DNS Skill

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.

Category Index

Category	Lines	Description
Troubleshooting	L35-L39	Diagnosing and fixing common Azure DNS issues like record resolution failures, misconfigurations, propagation delays, and permission or zone-related errors.
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	Private DNS zone scale limits, record count and name constraints, performance and subscription quotas, and design considerations when planning large private DNS deployments
Security	L56-L66	Protecting DNS zones/records from deletion, configuring DNS security policies and logging, using DNSSEC for public zones, and securing Azure DNS with RBAC, alerts, and built-in protections.
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-L89	Using Azure CLI, PowerShell, or portal to create/manage DNS zones and records, and to delegate subdomains or import/export DNS zone files for automation and integration.
