DNS

On February 1, 2006, the University of Oregon will restrict certain types of access to its DNS servers to UO users only. This change can only adversely affect those users who have manually entered DNS settings into their computer or device. Here's how to verify your DNS settings:

Mac OS X

  1. From the Apple menu, select System Preferences
  2. Click the Network button
  3. From the Show menu select your network interface (Ethernet or wireless, for example)
  4. Click the TCP/IP button
  5. Check the DNS Servers box--make sure the box is blank

Mac OS 9

  1. Open the TCP/IP Control Panel. (Apple menu -> Control Panels -> TCP/IP)
  2. Change the user mode to Advanced. (Edit-> User Mode -> Advanced)
  3. Look at the "Connect via:" setting and remember it (or write this down). It will typically say "Ethernet" or "ppp."
  4. Verify that the "name server addr.:" field is blank for each "Connect via:" drop-down. Make sure you restore the "Connect via:" setting to what you started with.

Windows XP

  1. From the Start Menu select Control Panel
  2. Right-click on your network connection and select Properties
  3. Double-click on "Internet Protocol (TCP/IP)"
  4. Make sure that the "Obtain DNS server address automatically" is selected

Unix:

If you are off-campus, and not connecting through UOnet, then check your resolv.conf, usually found in /etc/resolv.conf to verify that you are not using 128.223.*.* for name resolution.
