A parked domain is a domain name that has been registered but is not associated with an internet service such as a website or email hosting. In other words, it is a domain name that was acquired but is not currently in use. It is instead "parked" for future use.
Whereas most domains we’re familiar with point to a web page (for example, the domain name humanity.com points to the TCP Humanity website homepage), parked domains usually point to either a basic “parked domain” page or can redirect visitors to the same web page as another, more primary domain name. In this case, the parked domain is referred to as an “alias domain” for the primary domain.
