There are lots of ways to point a domain to another domain or subdomain and one of them is by setting up a CNAME record. If you own a domain and you've created a website through some on-line service which 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 as a result is that www.your-domain.com will be in the Internet browser address bar while it opens the already mentioned site from the servers of the third-party provider. 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 pointing to one provider and functioning email addresses with a different one. The CNAME record is always an alpha string, not a number, and sometimes additional configuration may be necessary with the other company.
