    Sites I have in my Blacklist are accessible.
    www.opendns.com/welcome says I'm OK.
    OpenDNS Updater says Using OpenDNS?  Yes

    Router is NETGEAR WNR3500L and has not had past issues with OpenDNS name servers.

    Your IP address 69.42.6.49 is registered with OpenDNS network ID 22548695.  This may not be yours, but another OpenDNS user's network.  You should see this at https://dashboard.opendns.com/settings/

    If it is not your network where 69.42.6.49 is registered with, then you have to obtain another IP address from your ISP and to update your dashboard network.  If you cannot obtain another IP address, then open a support ticket to get your IP address removed from this other network.

    If 69.42.6.49 is registered with your dashboard network, then you would have to doublecheck your settings to see if the domains are really blacklisted, especially to raise a DNS query for domains which should be blocked to see if an OpenDNS IP address is being returned.

    "nslookup weird result"

    What exactly is so weird in your opinion?

    If figured out the weirdness.  Not so weird, just misunderstood.

    I mirrored my settings from the NETGEAR management pages (netgear.opendns.com/account.php...&c) to the OpenDNS Dashboard pages (dashboard.opendns.com/settings), went to dinner for the day & it all works, now.

    Was there something in the filtering architecture that changed recently?
    Seems like the settings I had over at netgear.opendns.com were being ignored.

    Ah, this is new information!

    It is known that Netgear LPC and OpenDNS Home are incompatible services.  You cannot use both at the same time although when you executed the nslookup above, LPC was disabled and you just had OpenDNS Home effective.  Whatever, it seems you tried to use both at some time, and this is why your filtering didn't work reliably.

    If you want to use Netgear LPC, you must delete the network at https://dashboard.opendns.com/settings/ and your only dashboard is at https://netgear.opendns.com/
    In contrast, if you want to use OpenDNS Home, you must disable LPC on the router and configure a network at https://dashboard.opendns.com/settings/.

    To the best of my knowledge, I didn't previously have both configured; I was using ONLY the interface at netgear.opendns.com and hadn't configured my network on dashboard.opendns.com at all ever.

    I'm not aware that I changed anything on my router to stop using LPC. I don't recall there being a router setting for LPC on my rev 1 WNR3500L; I don't recall the product literature touting that as a feature of that device. All of that is what drove me to use OpenDNS in the first place.

    Since I migrated the settings to dashboard.opendns.com filtering is working as expected, but I feel like it's a stop gap measure, not "the solution."

    How do I get back to just having the Netgear interface in use like I did before?

    You're confusing me.

    "hadn't configured my network on dashboard.opendns.com at all ever. "

    How can this be?  This is in conflict with: "I mirrored my settings from the NETGEAR management pages (netgear.opendns.com/account.php...&c) to the OpenDNS Dashboard pages (dashboard.opendns.com/settings)" meaning that you configured your network for OpenDNS Home.

    "I don't recall there being a router setting for LPC on my rev 1 WNR3500L"

    Weird.  How could you then ever do something at the NETGEAR management pages (netgear.opendns.com/account.php...&c).  This can be accessed with LPC enabled only.

    "How do I get back to just having the Netgear interface in use like I did before?"

    This is again in contrast to "I don't recall there being a router setting for LPC on my rev 1 WNR3500L".  How can you "get back" what never was there???

    Well, these are the instructions for LPC:
    http://kb.netgear.com/app/answers/detail/a_id/25687/

    As said above, you must also delete your network at https://dashboard.opendns.com/settings/ if you want to use LPC.

    Probably the confusion lies in that I never had Netgear LPC running locally using the NETGEAR genie app.  My use of NETGEAR LPC has always been solely through the OpenDNS website.  There's a purple banner at the top of the page at dashboard.opendns.com that says "Click here to manage your NETGEAR device..." and that is what I've always done since day one with OpenDNS, and filtering has always worked until this week on or about 20161124.  Hence, my post the following morning on the 25th.

    Now it was AFTER your first response Thursday at 12:55 that I went to the Dashboard, clicked the Settings tab, and mirrored my settings from netgear.opendns.com to dashboard.opendns.com/settings, and my filtering began behaving as expected later that day, but I hadn't done that before.

    NOW what I'd like to know is how (or maybe if?) I can get back to using ONLY the settings pages I had been using at netgear.opendns.com/account.php

    If I blow away my filtering selections at dashboard.opendns.com/settings, will my settings at netgear.opendns.com work?

    So, a couple of things, and all the little pieces now fit:

    My router is a WNR3500Lv1
    The product literature for that rev didn't include anything about the NETGEAR genie app, and it wasn't included on the install disc.
    The WNR3500Lv2 router did.

    That's ONE thing.

    The SECOND thing is the NETGEAR OpenDNS app.
    I ran it and found that LPC had been disabled, so I enabled it like it's supposed to be.

    Then I removed all of my filtering settings from the Settings page at dashboard.opendns.com/settings.

    At this moment, the only filter settings are at netgear.opendns.com and everything seems functional.

    As a cross check I opened a command window and ran the nslookup, again.  Results follow:

    nslookup -type=txt debug.opendns.com
    1.1.168.192.in-addr.arpa
    primary name server = localhost
    responsible mail addr = nobody.invalid
    serial = 1
    refresh = 600 (10 mins)
    retry = 1200 (20 mins)
    expire = 604800 (7 days)
    default TTL = 10800 (3 hours)
    Server: UnKnown
    Address: 192.168.1.1

    Non-authoritative answer:
    debug.opendns.com text =

    "server m11.sea"
    debug.opendns.com text =

    "device 000030EC1A82B130"
    debug.opendns.com text =

    "flags 422 0 8010 1940400FF0040081CC3"
    debug.opendns.com text =

    "originid 22548643"
    debug.opendns.com text =

    "actype 1"
    debug.opendns.com text =

    "bundle 22548643"
    debug.opendns.com text =

    "source 69.42.6.49:32803"


    When you wrote "If you want to use Netgear LPC, ..." an instruction to "run NETGEAR Live Parental Controls OpenDNS Management Utility, and set Live Parental Controls to 'enabled' "  would have sufficiently jogged my memory and saved us a bit of this back-and-forth.

    All good now, I think, though.

    Thanks for your perseverance.

    I see now that you have LPC enabled ("device 000030EC1A82B130").  However, your  IP address 69.42.6.49 seems now to be registered with another OpenDNS Home network 22548643.  So there is still the risk of different settings (LPC and another dashboard network) taking effect.  Just in case you're still facing issues with consistent filtering.  You had to obtain another IP address, or you had to open a support ticket, so that staff can look into this.
