What do you mean by domain parking?

[Imrat Khanna]

Domain parking is a popular practice in the Internet world where people get cheap domains reserved for future use and keep (park) them idle until they are constructed and hosted. Such domains won’t be accessed, and if tried, will appear an “under construction” message on their default pages.

There are some domain registrars that allow you to get your domain parked free of cost.
