There are various ways to direct a domain to a different domain or subdomain and one of them is by setting up a CNAME record. In case you own a domain name and you've developed 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 redirects to subdomain.provider.com. What you'll achieve by doing this is that www.your-domain.com will be in the Internet browser address bar while it opens the already mentioned 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 functioning, so you can't have both a CNAME record pointing to one provider and working e-mail address with another. The CNAME record is always an alpha string, not a number, and sometimes further configuration may be necessary with the other provider.
