There are lots of ways to redirect a domain name to another domain or subdomain and one of them is by setting up a CNAME record. In case you own a domain name and you have set up a site through some on-line service which supplies you with a service subdomain, you can easily link the two by creating a CNAME record for your-domain.com that points to subdomain.provider.com. What you will achieve as a result is that www.your-domain.com will be in the web browser address bar while it opens the already mentioned Internet 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 can't have both a CNAME record pointing to one provider and working email addresses with a different one. The CNAME record is always an alpha string, not a number, and in some cases additional configuration may be required with the other company.
