There are various ways to point a domain to a different domain or subdomain and one of them is by creating a CNAME record. When you own a domain and you've set up a website through some on-line service that provides 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 as a result is that www.your-domain.com is going to be in the browser address bar while it opens the already mentioned site from the servers of the third-party company. It is essential to know that if you set up a CNAME record, any other records your domain address may have will stop functioning, so you cannot 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 in some cases further configuration may be necessary with the other provider.
