Recommendations

After adding a private zone name, configure its DNS records before you set its resolution scope. Within this resolution scope, the resolution records for the domain name overwrite its public records. Private zone supports two modes for adding records, Form Editor Mode and Visual Editor Mode.

Note
  • The steps for configuring regular zone are the same as those for acceleration zones. However, for acceleration zones, you can customize resolution ACLs and set weights for A, AAAA, and CNAME records.

  • Before adding PTR records, you need to configure a reverse lookup zone. For more information, see Reverse lookup and PTR records
