Adding Record Sets

Add record sets to a domain name.

For details, see Table 1.

- After a zone is created for a domain name, the system automatically creates the SOA and NS record sets.
- A maximum of 500 record sets can be added in 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.

Creating a Wildcard DNS Record Set | Add a record set that matches all subdomains. | Wildcard DNS resolution does not support NS record sets.
