There are numerous ways to direct a domain to an alternative domain or subdomain and one of them is by creating a CNAME record. In case you own a domain name and you have created a website using some on-line service which supplies you with a service subdomain, you could easily link the two by creating a CNAME record for your-domain.com that directs to subdomain.provider.com. What you will achieve by doing this is that www.your-domain.com is going to be in the 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 create a CNAME record, any other records your domain may have will stop working, so you cannot have both a CNAME record directing to one provider and working e-mail address with another one. The CNAME record is always an alpha string, not a number, and sometimes additional configuration may be required with the other company.
