That is probably your routers address. I have much better luck using the DNS my isp provides or using openDNS. If you are dual booting you can get this information from windows or go to your isps website and it should list the proper DNS. If you are using dhcp you can go: System->Admin->Network, hilight the device that connects of internet, hit edit. Check the box that says automatically obtain DNS infomation from provider. That should get it.
