Given that much detail your average tech would wait for more details.
Hi, today I faced a problem that was funny.
My ISP's default DNS is 208.67.222.222, 208.67.220.220 (OpenDNS public DNS IPs). Few days back I was able to changed the DNS to something else, like 8.8.8.8 (Google's public DNS), but right now when I try to change it, it disconnects my Internet. The interesting part is that I can still ping 8.8.8.8 with no problem.
Appreciate your help.
