Alibaba Cloud DNS is an intelligent domain name resolution service developed by Alibaba Cloud based on the DNS server of HiChina. Alibaba Cloud DNS aims to provide stable, secure, and efficient domain name resolution and supports the resolution of domain names that are not registered with HiChina to IP addresses outside mainland China.

After you register a domain name, you have only the ownership of the domain name. You cannot directly use the domain name to visit your website or use the domain name as an email address suffix to send and receive emails. This is because a domain name is translated from an IP address and is used to facilitate memorization. You must use the original IP address to access a server over the Internet. A DNS server maps a domain name to the relevant IP address. Domain name resolution is required when you use a domain name.

The topics in API Reference describe how to call API operations to manage domain names.

Before you call these operations, make sure that you have read the introduction to Alibaba Cloud DNS and the API usage specifications.
