1---2name: azure-dns3description: Expert knowledge for Azure DNS development including decision making, architecture & design patterns, limits & quotas, security, configuration, and integrations & coding patterns. Use when managing DNS zones/records, Private DNS/resolvers, DNSSEC, reverse DNS, or migrating legacy Private DNS, 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 Virtual Network Manager (use azure-virtual-network-manager).4---5# Azure DNS Skill67This skill provides expert guidance for Azure DNS. Covers 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| Decision Making | L34-L38 | Guidance for planning and executing migration of legacy Azure Private DNS zones to the new DNS zone model, including compatibility, steps, and considerations. |24| Architecture & Design Patterns | L39-L44 | 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. |25| Limits & Quotas | L45-L51 | DNS record, zone, and query limits for public and private Azure DNS, including quotas, scaling behaviors, and constraints when designing Private DNS zones and usage. |26| Security | L52-L62 | 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. |27| Configuration | L63-L75 | 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. |28| Integrations & Coding Patterns | L76-L85 | 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. |2930###
