There are lots of ways to redirect a domain name to a different domain or subdomain and one of them is by creating a CNAME record. In case you own a domain name and you have set up a website using some on-line 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 redirects to subdomain.provider.com. What you will achieve in this way is that www.your-domain.com is going to be in the browser address bar while it opens the already mentioned 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 address 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 often more configuration may be necessary with the other provider.
