What are parked and addon domains? What about subdomains? • Parked domain is the domain name that leads to same website as other domain name. The domain is parked on the top of other domain. • Add-on domain is a domain which is displayed as a complete different website. If you are opting for giving fee for add-on domain, it means that you are giving permission for hosting another website, along with the main website. • Addon domain or parked domain makes the hosting provider to add an account to the existing hosting account. • Subdomains can work with the existing domain names and you will not be required to make a separate addition to it in your hosting account.
