How Are Zones Queried to Resolve a Domain Name?

When a domain name resolution request is initiated, a matched subdomain is first queried.

  • If a zone is created for the subdomain, the system returns the result based on the zone configuration.
  • If a zone is not created for the subdomain, the system queries the domain name in the zone created for the domain name.

For example, suppose you have created one zone named example.com and added an A record set to it, with the Name field set to www, and you have also created another zone named www.example.com but have not added an A record set to this zone.

If a visitor accesses www.example.com, the domain name is first queried in the zone named www.example.com. However, no result will be returned because no record sets have been added to the zone.
