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.
