CNAME

The CNAME record, which stands for Canonical Name, is a specific entry type within the Domain Name System (DNS). Its function is to point one domain name to another domain name, indicating the location where web pages are accessible to internet users. We utilize CNAME records when we need to associate a custom domain name with a service, such as linking a custom domain to a blog platform.

For example, if you have a domain and wish to use a subdomain like "blog.mondomaine.com" for your blog, you would create a CNAME record to point "blog.mondomaine.com" to the designated service address, such as "ghs.googlehosted.com". The process involves creating the CNAME record for the desired subdomain and associating it with the target host address.

We note that the process of creating a CNAME record can take time to propagate across the DNS system, potentially requiring up to 48 hours for full effect. The specific method for creating a CNAME record varies depending on the hosting service provider we use.
