CNAME record dns

 What is cname record in dns?

Say your server name is local92.avi.com and it resolves a public ip of say 103.23.24.25

Now you want the same server should be used for another purpose and also should resolve the same public ip address. 

Say you want to call your server using this name smsplus.avi.com, then the same ip should resolve. In that case you need to configure cname record in your dns server forward lookup zone configuration file. 

Create a new cname record there. 

Alias: smsplus

FQDN: local92.avi.com

It will take some time to propagate in the internet. Now when you call smsplus.avi.com then 103.23.24.25 this ip should resolve. 

Use cases:

Say in your server have some more resources to utilize. Instead of purchasing another server for another purpose, you can use the same server to do so.
