Billing methods
Alibaba Cloud DNS PrivateZone uses the pay-as-you-go billing method. You are charged for authoritative zones and the resolver feature.
Authoritative zones: billed by basic configurations and the number of back-to-origin requests. Bills are generated and settled on a daily basis. If you delete a zone within the same day you create the zone, you are not charged.
Resolver feature: billed by the number of source IP addresses of an outbound endpoint and the number of DNS requests that an outbound endpoint forwards. Bills are settled on a daily basis.
Billing rule
Authoritative zones
Billable item | Pricing | Description |
Number of zones | 0.015 USD per zone per day | You are charged USD 0.015 per day for each zone in an Alibaba Cloud account. |
Number of requests in each zone | 0.004 USD per 10,000 requests | You are charged USD 0.004 for every 10,000 back-to-origin requests that the DNS server processes each day in an account after the specified time to live (TTL) period ends. |
Resolver feature
If you do not need to use the resolver feature, you can ignore this billing item.
Billable item | Pricing | Description |
Source IP address of an outbound endpoint | 0.15 USD per source IP per hour | You are charged USD 0.15 per hour for each source IP address of an outbound endpoint in an account. |
Number of DNS requests that an outbound endpoint forwards | 0.004 USD per 10,000 requests | You are charged USD 0.004 for every 10,000 DNS requests that an outbound endpoint forwards in an account. |
Examples
The following zones are added to Account A: example.com, example.aliyundoc.com, and inner.example.local.
The DNS server receives 64,131 back-to-origin requests from the three zones in Account A in one day.
Account A is charged USD 0.075 in total for that day, including USD 0.045 for the usage of the three private zones and USD 0.03 for resolving the back-to-origin requests. The fee for resolving the requests is calculated in the following manner: Divide 64,131 by 1,000. The result is 6.4131. Round 6.4131 to 6.41 and multiply the number by 0.004. The result is rounded to 0.03.
Description
TTL caching is used for DNS requests. In each zone, the number of billable back-to-origin requests per day is the number of requests minus the number of cache hits within the TTL period.
For example, the TTL for the domain name www.test.com is set to 30 seconds and 1,000 requests per second are sent to the DNS. In this case, all requests within the TTL period are free of charge. The request that is sent after the specified TTL period ends is billed. All subsequent requests that are sent within a new TTL period are free of charge.
You can view the total number of back-to-origin requests on the Query Volume page in the Alibaba Cloud DNS console.
Note
In most cases:
A longer TTL period causes fewer back-to-origin requests and lower fees. However, a longer period of time is required to change the IP address of a domain name within the corresponding TTL period.
A shorter TTL period causes more back-to-origin requests and higher fees. However, a shorter period of time is required to change the IP address of a domain name within the corresponding TTL period.
