Domain Name

Domain Name, the name of a computer or computer group on the Internet composed of a series of dot-separated names, is used to identify the electronic location of the computer during data transmission (sometimes it also referred to as geographical location, geographic domain name, a local region with administrative autonomy). A domain name is an IP address with a "mask" on it. The purpose of a domain name is to facilitate the memorization and communication of a set of server addresses (website, email, FTP, etc).

CNAME Domain Name

After Baidu AI Cloud CDN accesses the accelerated domain name, the system assigns a "CNAME domain name " to the corresponding domain name. The accelerated domain name is used to complete the CNAME configuration at the domain name service provider to point to the CNAME domain name. After the configuration takes effect, the work of domain name resolution will be officially transferred to Baidu AI Cloud, and all requests for this domain name will be transferred to the Baidu AI Cloud CDN node.

CNAME Record

Namely: Alias record This record allows you to map multiple names to the same computer. It is usually used for computers that provide both WWW and MAIL services. For example, there is a computer named "host.mydomain.com" (A record). It provides both WWW and MAIL services in order to facilitate user access to the service. Two aliases (CNAME) can be set for this computer: WWW and MAIL. The full names of these two aliases are "www.mydomain.com" and "mail.mydomain.com". Actually they all point to "host.mydomain.com".

DNS

Domain Name System, a distributed database on the Internet that maps domain names and IP addresses to each other, enables users to more easily access the Internet without having to remember IP strings that can be read directly by machines. The process of obtaining the IP address corresponding to a host name from a host name is called domain name resolution (or host name resolution).
