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 on-line service which supplies 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 are going to achieve in this way is that www.your-domain.com is going to 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 very important to know that if you set up a CNAME record, any other records your domain may have will stop working, so you cannot 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 sometimes further configuration may be needed with the other company.
