There are various 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've created a site through some online service which supplies you with a service subdomain, you could easily link the two by creating a CNAME record for your-domain.com that directs to subdomain.provider.com. What you are going to achieve with this 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 name may have will stop functioning, so you cannot have both a CNAME record pointing to one company and functioning e-mail address with a different one. The CNAME record is always an alpha string, not a number, and sometimes further configuration may be required with the other company.
