There are various ways to redirect a domain name to a different domain or subdomain and one of them is by setting up a CNAME record. If you own a domain and you've created a website through 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 points to subdomain.provider.com. What you will achieve in this way is that www.your-domain.com is going to be in the Internet browser address bar while it opens the already mentioned site from the servers of the third-party provider. You should 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 provider and functioning email addresses with another one. The CNAME record is always an alpha string, not a number, and frequently further configuration may be necessary with the other provider.
