    What does http://welcome.opendns.com/ return?

    Copy & paste the complete plain text outputs of the following diagnostic commands here:

    nslookup -type=txt debug.opendns.com.
    nslookup netflix.com.
    nslookup www.netflix.com.

    When I clicked on the welcome.opendns.com link, it brings me to a website that tells me that

    I am not using opendns yet and I need to restart my computer.  I restarted my laptop and tried again.

    Still I see the same website which tells me that I am not using opendn.

    If you don't use OpenDNS, then you cannot block anything with it.  Start over with review of the configuration of the OpenDNS resolver addresses.  I can give no more details, as you didn't post the command outputs.

    Do I need to add 208.67.222.123 and 208.67.220.123 in addition to specifying my current IP address

    in my OPENDNS account?

    Thanks.

    Do I need to add 208.67.222.123 and 208.67.220.123 as my DNS servers in my router setting in addition to specifying my current IP address in my OPENDNS account?

    Thanks.

    Did you think you will start using OpenDNS if you configure different resolver addresses?  Hardly!  But worth a try.  At least it keeps you busy with irrelevant things...

    You should better decide to collaborate and answer the questions being asked.

    The following is what I see after applying the commands you wanted me to try.

    Thanks.

    As can be clearly seen, you do not use OpenDNS, but another DNS service's IPv6 address.  You either disable IPv6 connectivity on the router or on the computer, or you try to configure the following IPv6 resolver addresses:

    ::ffff:d043:dedc
    ::ffff:d043:dcde

    Also, you forgot the trailing dot, therefore you didn't query netflix.com, but netflix.com.Broadcom.net.

    Hi,

     

    I disabled the IPv6 connectivity and the following is the internet setting report on my Linksys EA6700 router.

    Could you take a look?

    Thanks,

    This looks good.  Does it work now?  http://welcome.opendns.com/
    Is www.netflix.com being blocked?

    When I tried it at home last night, it still didn't work.

    Are the DNS settings for IPv4 OK?

    68.105.28.11 doesn't look to be OpenDNS server.

    Is that OK?

    "When I tried it at home last night, it still didn't work."

    Last night IPv6 was not disabled, right?  This was the identified reason for not working.

    "Are the DNS settings for IPv4 OK?"

    No reason to ask, as you cannot change them on this router.  These ISP DNS addresses are not really ok, but this is how this Linksys router firmware is built.  These values should be overwritten by the DHCP/LAN settings which are to propagate this information to the end user devices, with the downside that local name resolution will be impacted or broken.  But you'll have to live with this as long as you use this router and firmware.

    Unless this router is impacted by a known Linksys problem it should work now for using OpenDNS.  If you are in doubt, visit the two links above, and post the outputs of the diagnostic commands again (this time regarding the trailing dots).

    It worked maybe for one minute, but after a while, somehow, I was able to access netflix.com.

    Afterwards, I can't access my rounter homepage to check out the internet settings any more.

    Could you remcommend a router that will work with OpenDNS?

     

    Thanks.

    I meant to say that I can't access my router homepage anymore after somehow netflix.com is unblocked.

    Thanks.

    Despite the configuration page you pasted, the diagnostic commands clearly show that your DNS traffic is going out via IPv6, which OpenDNS does not filter.

    Perhaps whatever caused you not to be able to reach your routers home page reset the settings on your router, but if it is letting DNS traffic to go out via IPv6 OpenDNS will not work for you. You need to review the settingso n your router to make certain that IPv6 is disabled.

    "I can't access my rounter homepage to check out the internet settings any more."

    You didn't say how you are accessing your router.  It should always work with using its IPv4 address instead of a hostname.

    "Could you remcommend a router that will work with OpenDNS?"

    There are so many routers out there which perfectly work with OpenDNS.  Just go through the huge list of router instructions provided by OpenDNS here.  But we are still not at the end with your current router.

    Regarding your last command output, this non-OpenDNS DNSv6 address is even not responding to any DNS queries at this time.  It would look like no internet connection at all.  And therefore Netflix seems to be blocked as everything else too.  It's  because you have disabled IPv6 on the router, but not so on the computer.  You must disable IPv6 on the computer too to prevent it from attempting IPv6.  Go into the network properties of your active connection and uncheck the box beside Internet Protocol Version 6.  Then confirm everything with "Ok".

    Then try again with visiting http://welcome.opendns.com/ and maybe post the command outputs again:

    nslookup -type=txt debug.opendns.com.
    nslookup netflix.com.
    nslookup www.netflix.com.

    I can't access the router by using 192.168.1.1 which is what I have been using.  Even though I can access Internet

    using chrome browser, when I type in your commands, I got those responses.  

     

    Even if I can disable my computer IPv6, I would also have to disable all other computers's IPv6 in the house.

    That doesn't seem like a good solution for me.    To me this means no matter what I do to the router settings,

    users can bypass those restrictions.  Is there any other way?

    My suggestion to you is that rather than continuing worrying about being able to block Netflix via OpenDNS you set that aside and figure out what is going on with your router and it's console. You have far more serious problems going on if you can't access that.

    Once that's resolved, and you can see what your router is actually configured to do you could then revisit OpenDNS.

    I just changed my router setting to static IP from DHCP and specified OpenDNS server for DNS.

    Now it seems to work.

    Thanks.

    "To me this means no matter what I do to the router settings, users can bypass those restrictions."

    Rather not.  It merely looks like you will break the internet connection or at least DNS, so that nobody can access anything at all.

    "I just changed my router setting to static IP from DHCP and specified OpenDNS server for DNS."

    In case you did this on the WAN side and your ISP didn't provide you with a static IP address, this will soon cause IP address conflicts, resulting in no internet connection for your network when your ISP changes your IP address, currently 68.101.97.31.

    "I can't access the router by using 192.168.1.1 which is what I have been using.  Even though I can access Internet"

    As mattwilson9090 suspected, your router seems to be really problematic and doing funny things when settings are changed.  This is merely a case for your router support and unrelated to OpenDNS.

    After I reset the router, I can access the router the same way as before.  However, I think my router doesn't behave correctly as it is configured when the connection type is DHCP.  As you mentioned I need to get more support from the router vendor and it is unrelated to OpenDNS.

    At least for the time being, when I configure the IPv4 connection type to static IP.  It seems to work, but in order to have a permanent solution, I need to get some help from the router vendor or get a new router at this point.

    I have one more question.  After specifying youtube.com to be blocked, if I try to access youtube.com by typing the address in my internet browser, I see that it gets blocked.  But if I access youtube using an youtube app on my iphone, it doesn't get blocked.  Is there a way to have the youtube app access to be blocked as well?

     

    Thanks.

    "if I access youtube using an youtube app on my iphone, it doesn't get blocked."

    This is an indication that a browser uses different domains than the iOS YouTube app.  You can possibly find the related domains at https://dashboard.opendns.com/stats/all/topdomains
