What is CNAME?
A Canonical Name record (abbreviated as CNAME record) is a type of resource record in the Domain Name System (DNS) used to specify that a domain name is an alias for another domain, the "canonical" domain. All information, including subdomains, IP addresses, etc., are defined by the canonical domain.
CNAME stands for Canonical Name. CNAME records can be used to alias one name to another. For example, if your portal hosting is done in Foradian's server, it might normally be accessed through myportal.foradian.org. You may also want to access it through schoolname.myerp.com. One way to make this possible is to add a CNAME record that points schoolname.myerp.com to myportal.foradian.org. When someone visits schoolname.myerp.com they will see the exact same content as myportal.foradian.org.
How can I create a CNAME?
Each hosting service has slightly different ways to create CNAME records. Guidelines are provided here for some of the common services. When in doubt, check with the particular company you're using for additional help or instructions. Contact the support team of the company where you purchased the domain name.

I recently signed up for a service. It allows me to use my online portal application with my domain name. My domain is hosted with you and I need help in creating a CNAME record. To verify that I own my domain name, I want to create a special CNAME record. Since the portal is not a domain host, they aren't able to create the CNAME record.
The information I have is a unique string for the CNAME record and a destination. The string is demo The destination is ws1.portal.com
Basically, there should be a CNAME record for demo.[my_domain.com] that points to ws1.portal.com Remember to replace [my_domain.com] with your actual domain name. Once the CNAME record is created correctly, I'll be able to use the portal application for my domain.
