• You are notified by email or SMS message seven days before your subscription is due to expire.

• After the expiration, your DNS configurations are retained for another seven days. If you renew the subscription within the seven days, your DNS configurations are not affected. Otherwise, the configurations provided in the paid edition are deleted, and you can only use the configurations provided in the free edition.

2. Pricing

(1) Price for each edition

The following table lists the prices for the three Alibaba Cloud DNS editions.

(2) Price for DNS protection

Alibaba Cloud DNS provides two levels of DNS protection. The following table lists the price for each level.

The price of DNS protection is calculated by using the following formula: Price of DNS protection for one domain name × Number of top-level domain names. The number of subdomain names is not limited.

3. Number of domain names

• Each Alibaba Cloud DNS instance supports one domain name by default and does not limit the number of DNS records. You are charged for additional domain names and can add up to 100 domain names to an instance. The unit price of domain names varies based on the Alibaba Cloud DNS edition.

• If you add multiple subdomain names for a primary domain name and host these subdomain names separately, each subdomain name is billed as a primary domain name. The number of DNS records for each subdomain name is not limited.

3. Calculation formula

Subscription fee = Price of the edition that you purchase + Unit price of DNS protection × Number of domain names + Unit price of domain names × (Number of domain names - 1).

Example

For example, you subscribe to Alibaba Cloud DNS for one year and purchase the following items: Enterprise Ultimate Edition, DNS Attack Defense Basic, and 15 domain names.

The subscription fee is calculated by using the following formula: USD 1,469 = USD 81 + USD 86 × 15 + USD 7 × (15 - 1).
