There are various ways to redirect a domain to a different domain or subdomain and one of them is by creating a CNAME record. In case you own a domain and you have created a site using some on-line service that 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 will achieve with this is that www.your-domain.com is going to be in the browser address bar while it opens the already mentioned Internet site from the servers of the third-party company. You should know that if you set up a CNAME record, any other records your domain address may have will stop working, so you cannot have both a CNAME record directing to one provider and working e-mail address with another. The CNAME record is always an alpha string, not a number, and often further configuration may be necessary with the other provider.
