Record Set Overview

A record set is a collection of resource records that belong to the same domain name. A record set defines DNS record types and values.

**Table 1** Record set management
Operation	Scenario	Constraints
Adding Record Sets	View record set types supported by the DNS service and their configuration rules, and configure record sets for a domain name. For details, see Table 1.	After a zone is created for a domain name, SOA and NS record sets are automatically created. Up to 500 record sets can be added by an account.
Managing Record Sets	Modify, delete, and view record sets.	After a record set is added, its resolution line cannot be modified. You can modify the TTL, value, and description of the NS record set that is automatically generated. You cannot modify the value of the SOA record set that is automatically generated. You cannot delete or disable SOA and NS record sets that are automatically generated.
Configuring a Wildcard DNS Record Set	Add a record set that matches all subdomains.	Wildcard DNS resolution does not support NS and SOA record sets.
Searching for Record Sets	Search for, modify, disable, and delete record sets on the Dashboard > Record Set page.	None
Importing Record Sets	Batch import record sets.	Record sets are listed in .xlsx files, and each file cannot exceed 2 MB. Up to 500 record sets can be imported at a time.
Exporting Record Sets	Batch export record sets.	None
Migrating to Huawei Cloud DNS for Domain Name Resolution	Migrate an in-use domain name to Huawei Cloud.	Before the migration, obtain all record sets from your current DNS service provider. After the migration, change the DNS servers of the domain name to those provided by Huawei Cloud DNS in the domain name registrar's system.
