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 cannot modify or delete SOA and NS record sets automatically generated by the system.
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.
