The Domain Name System (DNS) is a system for naming resources (such as websites) that connect to the internet. If you're using Microsoft Windows, you can find your DNS Server Address by going to Start > Run. Type in 'cmd' (without the apostrophes) and hit Enter. Another window will open which is the command prompt. Type 'ipconfig /all'. This command will give you the Local Area Network (LAN) adapter that you currently have on your computer. Among the information on display is your DNS Server Address. If you're on a Mac, go to System Preferences > Network. Click on the Ethernet icon (if you're using ethernet) or on the Airport icon (if you're using WiFi. Your DNS Server Address will be found under the TCP/IP tab.
