Private DNS is pay-as-you-go. It is billed by the numbers of private domains and DNS requests and settled by calendar day. If a private domain is deleted in less than 24 hours after creation, no fees will be incurred.
Number of private domains: 0.015 USD/domain/day
Number of DNS requests: 0.004 USD/10,000 requests
test.com
, host01.demo.com
, and inner.example.com
.There is a TTL caching mechanism for DNS queries. The number of daily DNS requests in Private DNS is the number of requests minus the number of TTL cache hits. For example, if the TTL for requesting www.test.com
is set to 30 seconds, and the internal access to www.test.com
generates 1,000 DNS requests per second, then the requests within 30 seconds will hit the TTL cache, which are free of charge; the TTL expires after 30 seconds, and then DNS will request www.test.com
once at the origin server; therefore, only this origin-pull request is billable.
Note:
- The longer the TTL value, the lower the frequency of DNS origin-pull requests, the slower the domain name change takes effect, and the lower the corresponding fees.
- The shorter the TTL value, the higher the frequency of DNS origin-pull requests, the faster the domain name change takes effect, and the higher the corresponding fees.
