What is the difference between a parked domain and an active domain?

A parked domain and an active domain serve different purposes and have distinct characteristics:

Active Domain:
An active domain is one that is actively being used for a website, email service, or other online activities.
It typically has associated DNS records pointing to a web server or email server where the content or services for the domain are hosted.
Visitors accessing the domain name will be directed to the content or services hosted on the associated servers.
Parked Domain:
A parked domain, also known as a domain alias or domain pointer, is a domain name that is registered but not actively used for hosting content or services.
Instead of displaying a website or providing email services, a parked domain usually displays placeholder content provided by the domain registrar or hosting provider.
Parked domains are often used for reserving a domain name for future use, preventing others from registering the same domain, or for monetization purposes such as displaying advertisements.
In summary, an active domain is actively used for hosting content or services, while a parked domain is registered but not currently associated with any specific content or services
