Change DNS records at Azure DNS

Microsoft's managed DNS, configured through the Azure portal.

Adding a record

  2. Enter the Name (use @ for the root), pick the Type, set the TTL.
  3. Enter the value and click OK/Add.

Editing or deleting a record

  1. Click the record set in the list, change the value, and click Save.
  2. Use Delete at the top of the record-set blade to remove it.

Changing the nameservers

Gotchas at Azure DNS

  • Azure groups records into "record sets" — several values of the same type and name live in one set.
  • Azure uses an alias record set to point a root domain at an Azure resource.

After you save

DNS changes aren't instant. Resolvers keep the old answer until the previous record's TTL expires, so a record with a 4-hour TTL can take 4 hours to change everywhere. Use the Route Planner's live check to see what the world sees, and the troubleshooting page if it still looks wrong after the TTL has passed.
