You can set your computer fetch the site you are working to your computer. To do this you only need to change the host file on your computer. Before you start panicking and won't read any more, have in mind this is simpler then it sounds. If you are running a Linux computer then your host file is in the following folder /etc/hosts. On the Mac you find the host file in /private/etc/hosts. On Windows 7 and 8 you will find the host file c:\WINDOWS\system32\drivers\etc\. On windows you might have to choose to show the hidden files and folder in setup. On Windows it is recomended to open notepad as Administrator
Into this file you enter the ip address of the server (your hosting at 1984) and add the name of the domain. It should look like this:
Ip address yourdomain.is
188.8.131.52 orwell.is www.orwell.is
This way your computer will fetch the web site for orwell.is at the ip address 93.95.225.
It is very important to change the hosts file in a text editor like notepad or gedit, not a wordprocessor like LibreOffice or word in Microsoft Office
