There are various ways to point a domain address 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 website through some on-line service that provides you with a service subdomain, you can easily link the two by setting up a CNAME record for your-domain.com that redirects to subdomain.provider.com. What you will achieve by doing this is that www.your-domain.com will be in the browser address bar while it opens the already mentioned Internet site from the servers of the third-party provider. It is very important to know that if you set up a CNAME record, any other records your domain may have will stop functioning, so you cannot have both a CNAME record pointing to one company and working email addresses with another one. The CNAME record is always an alpha string, not a number, and sometimes additional configuration may be necessary with the other company.
