1---2name: azure-dns3description: Azure DNS Skill4---5# Azure DNS Skill67This 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.89## How to Use This Skill1011> **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 file1213> **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](https://github.com/MicrosoftDocs/mcp/blob/main/README.md)1415This skill requires **network access** to fetch documentation content:16- **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch` with query string `from=learn-agent-skill`. Returns Markdown.17- **Fallback**: Use `fetch_webpage` with query string `from=learn-agent-skill&accept=text/markdown`. Returns Markdown.1819## Category Index2021| Category | Lines | Description |22|----------|-------|-------------|23| Troubleshooting | L35-L39 | Diagnosing and fixing common Azure DNS issues like record resolution failures, misconfigurations, propagation delays, and permission or zone-related errors. |24| 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. |25| 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. |26| 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 |27| 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. |28| 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. |29| 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. |3031###
