There are lots of ways to redirect a domain to a different domain or subdomain and one of them is by setting up a CNAME record. If you own a domain and you have created a website through some on-line service which provides 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'll achieve by doing this is that www.your-domain.com will be in the 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 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 company and functioning email addresses with another. The CNAME record is always an alpha string, not a number, and often additional configuration may be needed with the other company.
