There are numerous ways to direct a domain to another domain or subdomain and one of them is by creating a CNAME record. In case you own a domain name and you have developed a site using some on-line service which provides you with a service subdomain, you could easily link the two by setting up a CNAME record for your-domain.com that redirects to subdomain.provider.com. What you are going to achieve in this way is that www.your-domain.com is going to be in the Internet browser address bar while it opens the already mentioned website from the servers of the third-party provider. It is essential to know that if you set up a CNAME record, any other records your domain name may have will stop working, so you cannot have both a CNAME record pointing to one company and functioning email addresses with a different one. The CNAME record is always an alpha string, not a number, and often further configuration may be needed with the other provider.
