In the video above Jeff shows how to quickly rectify the DNS invalid error that can occur when changing from Dynamic to Static IP address assignment or when making changes to the DNS settings in the Network > TCP/IP page.
To fix the DNS invalid, high-bit must be between 1 and 223 error message, set the Preferred DNS to 8.8.8.8 and the Alternate DNS to 8.8.4.4
This error occurs because there is no Alternate DNS set.
