said by Archangel83:Should I use AT&T DNS servers or switch out for Google or Open DNS. I have been warned about using an open public DNS system but also told by just as many the OpenDns or Googles DNS will be Better then my own ISP's. Thoughts Suggestions?
Whether public DNS service is better then ISP DNS service really depends on the ISP. In a little over ten years with AT&T (all the way back to "PacBell") I never had trouble with ISP DNS. And my current ISP, which service I've had for just over one year, seems equally reliable. However, some areas of California outside of the S.F Bay Area, and AT&T Midwest (former Ameritech) have had problems.
Drawback for OpenDNS is "redirect on error", which requires signing up an account to opt out.
