There is a simple tweak you can do. Which will result in your system (PC) instantly propagate DNS.

Follow these steps :

Firstly you will need to find a file named “hosts” and open it using any text editor.

In windows, the file is in here;

Code:
%windir%\system32\drivers\etc
Note : %windir% is the windows root directory like c:\windows

Then, you need to know your IP address. For Ex :

+===================================+
| New Account Info |
+===================================+
| Domain: domainname.com
| Ip: 64.69.46.210 (n)
| HasCgi: y

You’ll need to add these lines at the end of the “hosts” file.

Code:
64.69.46.210 www.domainname.com
64.69.46.210 domainname.com
*please note that you should not add the prefix “http://” infront of the domain names.

save the file, and you’ll be able to browse to your site immediately
