The CNAME record will point your domain or subdomain to the IP address of the destination hostname. So, if the IP of the destination hostname changes, you won’t need to change your DNS records as the CNAME will have the same IP.

1) Sign in to your Listedhosting account (The Sign In option is available in the header of the page)
2) Select Domains from the left sidebar and click the My Domain
3) Click on the Domain date of the domain you want to make changes to.
4) On the right side, click on DNS Management option to make changes.
