Category Index

Category	Lines	Description
Troubleshooting	L29-L32	Diagnosing and fixing common Azure DNS issues like record resolution failures, misconfigurations, propagation delays, and permission or zone-related errors.
Decision Making	L34-L37	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	L39-L43	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	L45-L48	Private DNS zone scale limits, record count and name constraints, performance and subscription quotas, and design considerations when planning large private DNS deployments
Security	L50-L59	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	L61-L72	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	L74-L83	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.
