Today while using a Wifi Analyzer I noted that I had 100% loss of ping packets to the DNS Server. To try to isolate the problem I hard wired my computer to my cable modem bypassing my wireless router. I then executed ipconfig /all to see all of my DNS IP addresses. I then pinged each one of the DNS addresses but noted that all of the DNS IP numbers timed out. I contacted Comcast and they said that my DNS configuration needed to be reconfigured.
What I do not understand is why I was able to browse the internet without a DNS. Furthermore at the DOS prompt I was able to ping some internet IP addresses successfully. Without a DNS server, shouldn't these requests have gone "Timed Out" as there was no DNS resolution? My pings were in the form of ping www.internetsite.com.
I cleared my ip address via ipconfig /release for both IPV4 and IPV6. I also cleared my DNS via ipconfig /flushdns. I re-registered everything with new IP addresses.
