What is the difference between CNAME and ALIAS records?

The skill explains that while CNAME aliases one domain to another, it cannot be used at the zone apex; ALIAS or ANAME records are required for root domain aliasing.

Does it include tools for DNS troubleshooting?

Yes, it includes essential CLI commands for tools like dig, instructions for flushing local caches, and methods for verifying global propagation.

What DNS providers does this skill support?

It provides guidance and configuration patterns for all major providers including AWS Route53, Google Cloud DNS, Azure DNS, and Cloudflare.

Can I automate DNS for Kubernetes using this skill?

Yes, the skill includes specific implementation patterns for using external-dns to automate record updates from Kubernetes Ingress and Services.

How do I minimize downtime during a DNS migration?

The skill outlines a standardized pre-change process involving TTL reduction 48 hours before changes to ensure rapid propagation and easy rollback.
