The main difference bewteen the addon domain and the parked domain is that the addon domain allows you to host more than one website on your account, while the parked domain is pointed to the main website on the account.
Sub domain * Lets say your domain is mysite.com. * You install a Message Board and put in in a directory called mysite.com/board/. * You can turn the directory board into a sub-domain by adding it as a sub-domain from your Control Panel. * Now you can access your Message board as either mysite.com/board OR board.mysite.com * This costs you nothing and is free. Parked Domain * You have two domains mysite.com and my-other-site.com. * mysite.com is the domain of your website and you want to add my-other-site.com. * You want them both to go to the same place. In other words, when someone types either www.mysite.com or www.my-other-site.com they will go to the same page(s) on your website. * In order to have additional parked domains you need to purchase them from a registry. * Register Parked domains here (open a new account if you don't have one registered) Add-On Domains * You have two domains mysite.com and my-other-site.com. * You want the two domains to be totally separate/independent websites. * In order to have additional add-on domains you need to purchase them from a registry. * Register Add-on domains here (open a new account if you don't have one registered) ---------------------------------------- http://webnet77.com/webstuff/parked-add-on-domain.html
