There are various ways to direct a domain name to a different domain or subdomain and one of them is by creating a CNAME record. If you own a domain and you have created a site through some on-line service which supplies you with a service subdomain, you can easily link the two by setting up a CNAME record for your-domain.com that points to subdomain.provider.com. What you will 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 site from the servers of the third-party provider. You should know that if you create a CNAME record, any other records your domain name may have will stop working, so you cannot have both a CNAME record directing to one company and working email addresses with another one. The CNAME record is always an alpha string, not a number, and sometimes further configuration may be required with the other company.
