There are lots of ways to redirect a domain name to another domain or subdomain and one of them is by creating a CNAME record. If you own a domain name and you've created a site through some online service that provides you with a service subdomain, you could easily link the two by setting up a CNAME record for your-domain.com that points to subdomain.provider.com. What you'll achieve as a result 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 provider. It is essential to know that if you create a CNAME record, any other records your domain address may have will stop working, so you can't have both a CNAME record pointing to one provider and functioning e-mail address with a different one. The CNAME record is always an alpha string, not a number, and sometimes more configuration may be needed with the other company.
