There are numerous ways to direct a domain to a different domain or subdomain and one of them is by setting up a CNAME record. When you own a domain name and you have developed a site using some online service which provides you with a service subdomain, you could easily link the two by setting up a CNAME record for your-domain.com that directs to subdomain.provider.com. What you will achieve in this way is that www.your-domain.com will be in the web browser address bar while it opens the already mentioned Internet site from the servers of the third-party company. It is important to know that if you create a CNAME record, any other records your domain name may have will stop working, so you cannot have both a CNAME record directing to one provider and working e-mail address with a different one. The CNAME record is always an alpha string, not a number, and sometimes further configuration may be needed with the other company.
