Alibaba Cloud DNS is a distributed database that maps domain names to IP addresses. You can use Alibaba Cloud DNS to resolve a domain name to the public IP address of an SLB instance.
ContextFor example, the domain name of your website is www.aliyun.com and the website runs on an ECS instance that uses the public IP address 184.108.40.206. After you create an SLB instance, the public IP address 220.127.116.11 is allocated to the instance. You want to add the ECS instance where your website runs to the backend server pool and resolve the domain name www.aliyun.com to 18.104.22.168. We recommend that you use the A record to resolve the domain name to the IP address.
Log on to the Alibaba Cloud DNS console.
On the Domains tab, click Add Domain Name to add a domain name.
On the Domains tab, find the added domain name, click Configure in the Actions column, and complete the DNS settings.
