Unable To Ping DNS Server On PC

  • 1

I’ve tried pinging my ISP’s, Google’s, Comcast’s, they all time out. I’ve run the gauntlet in cmd as well, I’ve /flushdns and /registerdns, I then tried pinging Yahoo.com and then /printdns. Still, no cure. I even attempted booting I to safe mode to see if that would perhaps fix it, but no such luck, I was still unable to ping the address and was unable to access the internet. I tried seeing if the firewall was perhaps blocking it, so I turned it off and it did nothing. I saw a *very* similar thread on here about 5 or 6 years back about a guy who had essentially the same problem and got it fixed. Someone mentioned ISP’s block DNS packets because of DDOS attacks? But that wouldn’t explain Google and Comcast’s unless if they block them too. I installed the telnet client to see if it would help ping DNS servers but to no avail.

The DHCP server’s ip address is: 192.168.0.1
DNS server’s address is: 97.64.183.164
Default Gateway Address: 192.168.0.1
When I typed the gateways address into my browser it did indeed take me to the router manufacturer’s website. Something new that didn’t pop up before when I typed in ipconfig /all is “lease obtained” and “lease expires” then dates and times following. The date for both was today and the time for obtaining this lease was 3:38:36 pm and the time that it expired was 3:47:41 pm. What does that mean, this worries me. It is currently 3:57 in Central Time where I am.

Thanks!

  1. The lease time indicates, at what time your computer got the ip address assigned to.
    When the lease expired is reached, and the computer has not used the ip address til that time, it gets released to use for other computers.
    So when you turn on the computer, that had assigned this ip address, and it was released already, it gets a new ip address of the address pool.

    Nothing, you have to worry about. Quite normal thing.

    But, when you put in the gateway ip address to your internet browser and login to your router, you should be able to figure out your online status.

    If the router shows, that there is no connection to your ISP, you have to call your ISP, that’s right.

    If your router is connected to the internet, you got an in house issue, where I guess, your ISP won’t or can’t help you.

  2. The DHCP server’s ip address is: 192.168.0.1
    DNS server’s address is: 97.64.183.164
    Default Gateway Address: 192.168.0.1
    Ok, the DNS server address is likely the root cause of the DNS resolution issue you’re experiencing. It should be 192.168.0.1 also. If calling your ISP’s support line doesn’t work, try checking your router’s settings and ensure it’s doing DNS and also that the DNS IP is the router’s LAN IP as well. If you’re having trouble doing it yourself, call the router manufacturer’s support line.

    When I typed the gateways address into my browser it did indeed take me to the router manufacturer’s website

    That actually should be the router’s web based management interface. Not the manufacturer’s website.

  3. This is because 97.64.183.164 is not a dns server but the ip of mospanxc01.mcomdc.com as shown by nslookup

    C:\Users\Charlie>nslookup google.com 97.64.183.164
    Server: UnKnown
    Address: 97.64.183.164

    *** UnKnown can’t find google.com: Query refused

    Here are dns servers in Missouri or you can use google’s dns servers

  4. Here is the nslookup results if I just look at the com

    C:\Users\Charlie>nslookup mospanxc01.mcomdc.com
    Server: cdns01.comcast.net
    Address: 75.75.75.75

    Non-authoritative answer:
    Name: mospanxc01.mcomdc.com
    Addresses: 2607:fdc8:1400::11
    97.64.183.164

    This is not a dns server
