Intelligent Resolution returns DNS results based on the requester's geographic location and ISP. This feature reduces resolution latency and improves website access speed. It supports various resolution lines, such as lines based on ISP, province, country, continent, or custom definitions. For more information, see Intelligent Resolution.

Alibaba Cloud DNS does not support direct instance downgrades. However, you can achieve the same result by binding your domain name to a different instance. For more information, see Upgrade, detach, replace, or downgrade an instance.

• If your domain is bound to a high-tier DNS instance and you want to move to a lower tier, you can bind the domain to a lower-tier paid instance instead.

• You can also use this method to downgrade the security protection level or reduce the number of supported domains for your current plan.

The Public Zone global cluster nodes are distributed across the following locations:

• Global nodes: US (Virginia), US (Silicon Valley), Mexico, Indonesia (Jakarta), Malaysia (Kuala Lumpur), Singapore, Japan (Tokyo), SAU (Riyadh - Partner Region), UAE (Dubai), Germany (Frankfurt), UK (London), France (Paris), Thailand (Bangkok), South Korea (Seoul), Philippines (Manila), China (Hong Kong), China (Beijing), China (Shanghai), China (Shenzhen), China (Hangzhou), China (Chengdu), China (Qingdao), China (Dalian - Local Region), China (Xi'an - Local Region), China (Tianjin - Local Region), China (Taiyuan - Local Region), China (Zhengzhou - Local Region), China (Nanjing - Local Region - Decommissioning).

• Cluster deployment is subject to change based on Alibaba Cloud's infrastructure development and is not covered by the SLA.

Each Public Zone instance supports one primary domain name by default, such as example.com. To support additional primary domain names, such as example.cn and example.net, you can increase the domain quota for your instance, up to a maximum of 100,000.

The DNS query limit and the number of DNS records under a single primary domain are two different concepts:

• DNS query limit: The maximum number of DNS queries that a single primary domain can receive per day. Free Edition has a limit of 100,000 queries per day per domain. Exceeding this limit may trigger dynamic rate limiting. All paid editions have no daily query limit.

• DNS records per primary domain name: The total number of DNS records (such as A, CNAME, and AAAA records) that can be configured under a single domain name. Free Edition, Personal Edition, and Enterprise Ultimate Edition support up to 100,000 records. Premium Edition has no limit.

No. None of the Alibaba Cloud DNS editions include DNS health check capabilities. To use health checks, you must separately activate the Global Traffic Manager 3.0 service. The service uses a pay-as-you-go billing model. For details, refer to Billing of Global Traffic Manager 3.0

Consider the following when selecting an edition:

• Enterprise account restrictions: Enterprise-verified accounts cannot purchase new Personal Edition instances. Existing Personal Edition instances can still be used and renewed.

• Global DNS coverage: Free Edition has only 4 DNS nodes in the Chinese mainland and 0 overseas. It does not support overseas acceleration or intelligent resolution. For global DNS coverage, upgrade to a paid edition (12 nodes in the Chinese mainland, 15 overseas).

• URL forwarding quota: Free Edition supports 2 URL forwarding records per domain name, Personal Edition supports 5, and Enterprise Ultimate Edition supports 10. Purchasing an SSL certificate does not increase the URL forwarding quota.

• Intelligent Resolution lines: Free Edition supports only basic region and carrier lines (China Unicom, China Telecom, China Mobile, CERNET). Province-level carrier lines and region subdivision lines are not available. Custom lines are only available for Enterprise Ultimate Edition and Premium Edition.
