There are lots of ways to redirect a domain name to a different domain or subdomain and one of them is by creating a CNAME record. When you own a domain and you have created a website through some online 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 will achieve with this 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 set up a CNAME record, any other records your domain name may have will stop functioning, so you cannot have both a CNAME record directing to one provider and functioning email addresses with another one. The CNAME record is always an alpha string, not a number, and frequently additional configuration may be necessary with the other provider.
