This article shows you how to parse the domain name cname, which is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

For domain name CNAME resolution, the domain name owner is in the domain name resolution operation center, select the CNAME resolution type, and then add "www" and "@" resolution records.

CNAME is called a canonical name, also known as an alias record. Such records allow multiple names to be mapped to the same computer, typically for computers that provide both WWW and MAIL services.

Domain name CNAME resolution elements: hostname, type, line type, corresponding value, TTL, priority, etc.

Hostname: the default is "www" and "@". If it is a second-level domain name, resolve the name of the second-level domain name, such as www.yisu.com, and the host name is "news".

Type: select CNAME here. There are 6 kinds of records, such as A record, MX record and TXT record.

Corresponding value: for example, in the virtual host we purchased, there is a "resolution alias" information. When we do domain name resolution, we can enter the resolution alias into the "corresponding value".

TTL: generally fill in 600,900, etc., indicating the meaning of 600s or 900s. TTL refers to the effective time of resolution (in seconds), which only affects the effective time of modification of resolution records. Additions take effect in real time, and the minimum is not less than 200s.

If the domain name and virtual host are purchased, the domain name resolution is done automatically by the system, without the need for us to add it manually, and the default is CNAME record type.
