There are many ways to redirect a domain name to a different domain or subdomain and one of them is by creating a CNAME record. When you own a domain and you have created a site through some online service that provides you with a service subdomain, you can easily link the two by creating a CNAME record for your-domain.com that redirects to subdomain.provider.com. What you will achieve with this is that www.your-domain.com is going to be in the browser address bar while it opens the already mentioned Internet site from the servers of the third-party provider. It is very important to know that if you set up a CNAME record, any other records your domain name may have will stop functioning, so you cannot have both a CNAME record pointing to one company and functioning e-mail address with a different one. The CNAME record is always an alpha string, not a number, and in some cases more configuration may be needed with the other company.
