Setup Alibaba Cloud DNS

Alibaba Cloud DNS is a highly available and scalable Domain Name System that provides authoritative DNS servers and DNS management services. Alibaba Cloud DNS uses globally distributed databases and synchronizes your data to global servers in real time. This ensures that all queries are rapidly responded to by the server in closest geographic proximity.

To use Alibaba Cloud DNS is quite easy.
Goto Alibaba Cloud DNS console, click on Add Domain Name

To use Alibaba Cloud DNS, you must add a domain name first. You can add domain names that are registered either with Alibaba Cloud or a third-party platform.

• For domain names registered with Alibaba Cloud, they are automatically added to the Alibaba Cloud DNS list after registration, and they cannot be deleted.
• For domain names registered with a third-party platform, you must manually add them to the DNS list in the Alibaba Cloud DNS console. Additionally, if the domain name is used by a DNS service provider other than Alibaba Cloud DNS, you must retrieve the domain name before adding it. The domain name can be deleted after being added.

After a domain name is added to the list, next is to update NS server to point to alidns.com.

Once the NS Server is validated by Alibaba Cloud, you can add DNS record to it to enable the service.

Alibaba Cloud DNS support all DNS record type.

Pay attention to a few configuration settings which are unique to Alibaba Cloud. These settings are not available in other DNS providers such as Cloudflare.

Alibaba Cloud DNS uses multiple backend connections to deliver intelligent GEO DNS services. That is, based on the visitor’s IP address, the most optimal resolution address is returned to allow users a fast and smooth access user experience.

For example, if a visitor is identified as a China Unicom user, the domain name is resolved to the IP address of the China Unicom server. If a visitor is identified as a China Telecom user, the domain name is resolved to the IP address of the China Telecom server.

You must specify an ISP line when adding a record. Alibaba Cloud DNS supports the following ISP lines:
China Telecom
China Mobile
China Unicom
CERNET (China Education and Research Network).
World Line (non-China based lines and specified at three different levels: the world, a continent, or a country).
