2. Pricing
(1) Price for each edition
The prices of the three editions are as follows:
| Edition | Personal Edition | Enterprise Standard Edition | Enterprise Ultimate Edition |
|---|---|---|---|
| Price (USD) | 7 per year | 29 per year | 81 per year |
(2) Price for DNS protection
Two DNS protection levels are available. The price for each level is as follows:
| DNS protection | DNS Attack Defense Basic | DNS Attack Defense Advanced |
|---|---|---|
| Unit price per domain name (USD) | 86 per year | 429 per year |
The price of DNS protection is calculated as follows: DNS protection price of one domain name × Number of top-level domains (TLDs). The number of subdomains 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 price per domain name varies depending on the edition.
- If you add multiple subdomains of the same second-level domain name, they are billed as a single domain name. The number of DNS records in each subdomain is not limited.
| Edition | Personal Edition | Enterprise Standard Edition | Enterprise Ultimate Edition |
|---|---|---|---|
| Unit price per domain name (USD) | 4 per year | 7 per year | 7 per year |
3. Calculation formula
The subscription price is calculated as follows: Price of an edition + Price of DNS protection × Number of domain names + Price per domain name × (Number of domain names - 1).
Example
Assume that 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 price is calculated as follows: USD 1,469 = USD 81 + USD 86 × 15 + USD 7 × (15 - 1).
