Parked domains (or aliases in the cPanel interface) are secondary domains that points to the user’s primary domain. If users visit the parked domain’s website, the primary website appears.
For example, cpanel.com is a parked domain that points to http://www.cpanel.net/. When you access http://www.cpanel.com, your browser returns the http://www.cpanel.net website.
Normally needing your parked domain nameservers to point to the server it is parked on.
