There are several ways to redirect a domain name to another domain or subdomain and one of them is by creating a CNAME record. When you own a domain and you have developed a site using some online service which supplies you with a service subdomain, you could easily link the two by creating a CNAME record for your-domain.com that redirects to subdomain.provider.com. What you are going to achieve as a result is that www.your-domain.com will be in the Internet browser address bar while it opens the already mentioned 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 directing to one provider and functioning email addresses with a different one. The CNAME record is always an alpha string, not a number, and sometimes more configuration may be necessary with the other company.
