In addition to how to add a record more commonly used, how to add a CNAME record is also a domain name related to common problems, today and we share how to add CNAME record resolution。
I. What is a CNAME record
The CNAME is an alias record (Canonical Name). When the DNS system queries the name of the CNAME on the left, it will turn to the name of the CNAME to the right and then query, tracing to the last PTR or A name, after a successful query will not respond, otherwise fail.
In layman's words, point a domain name to another B domain name, and then another B domain name A to provide an IP address, so that is a CNAME record.
second, the role of the CNAME record
CNAME records allow you to map multiple domain names to the same computer, typically for servers that provide several different services at the same time, such as the WWW and mail services computers.
third, how to add CNAME record parsing
We use www.elsyy.com to bind as an example to explain how to add CNAME record parsing.
1, the Host Records Office to fill in the search
For example: need to add search.elsyy.com resolution, only need to fill in the host record search, if you just want to add elsyy.com CNAME record resolution, the host record is left blank, the system will automatically fill in a "@" into the input box, @ The CNAME will affect the normal parsing of MX records, when added, we will explain the MX records later.
2. The record type is CNAME
3, the line type (the default is required, otherwise it will cause some users can not be resolved; The default effect is: All users except Unicom users, will point to) if your site is multi-line multi-IP or multi-server redundant load, according to the service of different IP corresponding to the line to set, other conditions set by default.
4. The record value is the domain name that the CNAME points to, such as: search.discuz.qq.com. Only the domain name can be filled in, the record will be automatically after the domain name to fill a ".", this is normal phenomenon
5, the MX priority does not need to fill in
6, the TTL is not set, the system will be automatically generated when added, the default is 600 seconds.
of course, can also be modified, but the general parsing time is determined by different regions of different DNS cache to delay, not necessarily set short is effective will be fast. For more Web site production Tutorials , please login to e-mentor network.
