Sometimes you may want to override the default DNS (Domain Name Server) settings on your computer so you can specify which DNS server is used, or which IP address should be used for a particular domain. There are two ways to do this: Specify the DNS and map IP addresses.
(1) Specify the DNS to be Used
This method tells your computer which DNS to use for all your internet browsing. Most home users have this set to “automatic” and the DNS is provided by the user’s ISP, but you can use any DNS you like (you can even make your own DNS if you’re keen).
Before you start you will need to know the IP address of the DNS to use – if you don’t know this you’ll need to ask your system administrator or ISP.
To set your DNS, you need to find the Internet Protocol window.
For Users on a Dial-up Connection:
Go to My Computer>Dialup Networking.
Right-click your internet connection and select Properties.
A window will open – click the Server Types tab. Click TCP/IP Settings.
For All Other Users:
Go to Control Panel>Network Connections and select your local network.
Click Properties, then select Internet Protocol (TCP/IP).
You will see a window like the one below – this is the Internet Protocol window. Select “Use the following DNS server addresses” and enter the desired DNS server(s) in the space(s) provided.
