“Computers live on numbers, we live on names, and DNS sits right in the middle, making the translation.” – Mirko Peters (00:23)
“So Azure DNS is Microsoft's managed DNS hosting service. In plain English, that means you never have to run your own DNS servers, patch them, or plan for higher availability.” – Mirko Peters (02:15)

Key takeaways
- Azure DNS is a managed hosting service for DNS zones, so you no longer run, patch or scale your own DNS servers.
- Public zones serve names to the internet and require delegation at your registrar, while private zones resolve only inside the virtual networks you link to them.
- Use alias records for Azure resources and recreate every existing record in Azure before switching name servers to avoid outages.
