    Do you run an Avast Security Suite?  Disable the "Secure DNS" option.

    If it is not Avast, then this looks like a Netgear problem, not an OpenDNS problem.

    Or feel free to raise a support ticket with OpenDNS.

    If you want to receive help here in the community forum, then enable LPC, and copy & paste the complete plain text output of the following diagnostic command to here:

    nslookup -type=txt debug.opendns.com.

    I am using an internet modem that has dhcp which assign IP address dynamically to Netgear and the dns from the ISP. Is this likely to be the problem ? if Yes how can I get it resolved?

    "unknown query type: text"

    You mistyped the command, "text" instead of "txt".  Try again now.  And the trailing dot is part of the command too.  I added a parameter because of the timeouts too.

    nslookup -timeout=8 -type=txt debug.opendns.com.

     "I am using an internet modem that has dhcp which assign IP address dynamically to Netgear"

    I'm not sure, it could be.  Copy & paste the complete plain text output of the following commands too:

    netsh interface ipv4 show config
    nslookup -timeout=8 whoami.akamai.net.

    This looks like you don't have DNS at all. :(
    Maybe even no internet connection.

    What's with the other command outputs I asked for?

    "Address: 74.125.47.5"

    It seems you used Google public DNS, not OpenDNS, when you executed this command.  Do you have Google DNS configured on the router or on the modem?  And something is wrong with your internet connection and the related configuration because of these many timeouts.

    Also, it is unusual that Netgear routers use the 10.0.0.0/24 subnetwork.  By default they use the 192.168.x.x. class of IP addresses.  Being different could be because of the use of another modem.  Is this modem or the Netgear router switched to bridged mode, or are both in NAT mode?

    As I said above, this looks like a Netgear problem, not an OpenDNS problem, so you better refer to Netgear support.  This is where the nerds for your problems are.
