| Should I be able to ping my ISPs DNS servers? OK I know that might seem like a simple question, but I am having a big problem..... I was switching out routers today and long story short it wasn't working out. I put my old router back in and it still had all the same settings.
Now I can not get on the net. Under the status bar on my router, it shows my static ISP IP along with the DNS servers from my ISP. It seems as though my router is connecting to my internet connection but I can not get on the net on any of my machines, wired and wireless.
I can ping my static IP address that my ISP assigned to me, but I can not ping either of my ISPs DNS servers.
What gives? I am not sure if my ISP is down and it was just coincidence with me switching out routers. If my ISP was down I would not think my router would detect all the settings from my ISP that it is..... | |

| Re: Should I be able to ping my ISPs DNS servers? In short, you should be able to ping DNS servers unless they are down.
I would try bringing up a command (DOS) prompt and typing ipconfig /release and then ipconfig /renew .
Then, see if you can ping the DNS servers. This may seem silly since you have a static IP, but try it anyway.
If that does not work, try using nslookup. Again, go to command prompt and type nslookup. That program can be used to troubleshoot several things. You can then type help at the prompt for more info. | |

Perhaps. Some ISPs drop pings to any of their infrastructure systems (or maybe just allowing pings from their "NOC"). Others use some form of QoS to drop the pings if the network or systems being pinged are busy. I had a discussion with an ISP about this awhile back. The benefits to them of blocking pings outweighed the drawbacks. | |

Atlanta, GA | Ping is part of ICMP and as such does not have to be transmitted or responded too, its very possible the DNS servers ignore pings.

| Re: Should I be able to ping my ISPs DNS servers? Like I said, my router detects my static IP address, ISP DNS servers, ISP gateway, and ISP subnet. It looks like it has everything to be connected to the internet, but NO CONNECTION on any of my machines. I get the damn error page when I open IE. Any thoughts? | |

Emmett, ID | Re: Should I be able to ping my ISPs DNS servers? Well everything is working fine now...... after several calls into tech support, it was a problem on their end. Works great now. Now that it is working ok, I can ping their DNS servers. Thanks for the help. | |

| Re: Should I be able to ping my ISPs DNS servers? I had a feeling it may have been an ISP issue. However, it is unusual for that sort of an issue to last more than a few hours. Nevertheless, all of the recent bad weather around the country could have caused some serious problems and may very well be the explanation for such a long outage.
I'm glad that you are back up and running.
