After registering a domain name, you will have the right to use the domain name, but cannot use it to directly access your website or send and receive emails using it as an email address suffix. This is because domain names are only part of an address conversion system that facilitates memorization. To access a server on the Internet, you must use an IP address. Domain name resolution is the process in which domain names are directed to IP addresses. "Domain Name Resolution" is essential for the use of domain names.

An intelligent domain name resolution service provided by the HiChina DNS (Domain Name Service) system designed to upgrade domain names across the network, Alibaba Cloud DNS provides stable, secure, and fast domain name resolution capabilities and can resolve non-HiChina domain names to overseas IP addresses.

Users can use the APIs described herein to resolve domain names.

Before using these interfaces, please ensure that you fully understand the Alibaba Cloud DNS product instructions and usage agreement.
