How to manually input DNS information on a Mac

Often when you connect to a network, your computer will be provided with certain network information automatically, such as IP address, gateway, and DNS settings.  However, there are some times when you will need to type in the DNS information manually.  This post shows you how to enter DNS information for your network on a Mac.  (The wording may vary slightly depending on which version of Mac OS X your computer is running.)

- Click on the Apple icon in the upper left corner of the screen.
- Select System Preferences.
- Select Network.
- Select the network whose DNS settings you want to change (if it's not already selected).
- Select Advanced.
- Select DNS.
- Click on the plus sign (+).
- Type in (or copy and paste) the DNS server's IP address.
- Press the <ENTER> or <RETURN> key.
- If you have a secondary DNS server, input that information as well by repeating the previous three steps.
- Select OK.
- Select Apply.
