There are various ways to redirect a domain name to an alternative domain or subdomain and one of them is by creating a CNAME record. In case you own a domain name and you have created a website using some online service which provides you with a service subdomain, you can easily link the two by setting up a CNAME record for your-domain.com that directs to subdomain.provider.com. What you're 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 Internet site from the servers of the third-party company. It is very important to know that if you create a CNAME record, any other records your domain may have will stop working, so you can't have both a CNAME record pointing to one company and functioning e-mail address with another one. The CNAME record is always an alpha string, not a number, and frequently additional configuration may be required with the other company.
