If your business has a website, be sure you understand who is in charge of maintaining your domain name registration. Anyone can find out who owns a domain by conducting a whois query on the address. The registration and expiration dates are listed in the report as well as the name of the company that can help renew an expiring domain. Most web hosts will register and maintain a .com or other top level domain name for your website, and some will charge hundreds of dollars to gain or regain ownership of your own domain.
