Security Update 2008-005 (#4): Internet connection broken; fix

Internet connectivity via a number of methods (AirCards, cable modems, DSL, etc.) is broken for many users who have applied Security Update 2008-005. Some sample reports:

1. "I discovered some time after installing the update that I intermittently had problems accessing the Internet using Safari.

• 208.67.222.222
• 208.67.220.220

to the DNS server list. If you currently have DNS entries, note them and keep them in a separate location but replace them with the aforementioned.
