Domain Parking allows you to redirect a domain name to another website. For example: If you have a hosting for http://www.domain1.com & you have also registered http://www.domain2.com then you can park it so that when someone visits http://www.domain2.com then they are instantly redirected to http://www.domain1.com
If you have a web hosting service with Pickaweb then you can redirect another domain name to it for free. This is called domain parking & is really easy to set up through your hosting control panel using the Parked Domains link.
The first thing that you need to do is to amend the nameservers of any domains that you wish to park to be exactly the same as those of your main hosting domain.
Check this if you need to change your nameservers.
Once you have done this please watch & listen to the following tutorial which will demonstrate how to Park the new domain.
