There are lots of ways to direct a domain name to a different domain or subdomain and one of them is by creating a CNAME record. When you own a domain name and you have developed a site through some online service that provides you with a service subdomain, you can easily link the two by creating a CNAME record for your-domain.com that directs to subdomain.provider.com. What you are going to achieve by doing this is that www.your-domain.com is going to be in the web browser address bar while it opens the already mentioned Internet 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 may have will stop working, so you cannot have both a CNAME record directing to one company and working email addresses with a different one. The CNAME record is always an alpha string, not a number, and in some cases further configuration may be needed with the other provider.
