Re: OpenDNS not working via IPv6

pnutts · ‎08-09-2014

All is fine with IPv4. My router is configured with the IPv4 OpenDNS server addresses all my devices retrieve their DNS server addresses from the router (the gateway address of 10.0.1.1 is specified explicitly as the default gateway and DNS server).

IPv6 isn't working and I don't know anything about IPv6 and not much networking, but I can follow instructions. I've read the support articles, searched the forum, and referenced externally linked resources, and pass all IPv6 tests. I'm using an Apple TimeCapsule 4th generation os version 7.6.4 (latest). I've entered 2620:0:ccc::2 and 2620:0:ccd::2 in the router as the IPv6 DNS server addresses. My computer is set to retrieve all IPv6 settings automatically. I prefer static IP addresses but I don't have many (if any) IPv6 dependencies on my home network so I'm good with dynamic IP addresses.

My router shows the IPv6 Default Route as fe80:2::72ca:9bff:fea8:10e2. It obviously also has the IPv6 WAN address and IPv6 delegated prefix, but it does not show an IPv6 LAN address. I don't know what static IPv6 address to enter for the IPv6 gateway. My computer has and IPv6 address, a temporary IPv6 address, and a link-local IPv6 address. Remember I don't know anything about IPv6. :) The router is set to not allow Teredo tunnels but does allow incoming IPsec.

I should re-evaluate if IPv6 is necessary for my home network. IPv6 functionality was enabled for Windows Homegroup functionality but if it's not needed for anything else I can do without Homegroup.

Thank you for any assistance. Thx.

Well... as a workaround on the PC I specified the IPv4 compatible address (::FFFF:10.0.1.1) for my router/DNS server and now the OpenDNS check reports I am successfully using OpenDNS. Maybe this is good enough if I want to keep IPv6 enabled.

...but the additional features like content filtering and stats do not reliably take effect, because you cannot register an IPv6 address with OpenDNS.

After opening a support incident I've disabled IPv6 as the solution.

I will mirror some content from the support ticket here for the benefit of other users looking for an answer.

IPv6 with content filtering is currently not supported with OpenDNS; however, we do have IPv6 capable DNS resolvers that you've mentioned (2620:0:ccc::2 and 2620:0:ccd::2); however this cannot be associated with your account since registration is IPv4 only.

I'd suggest setting IPv6 to Local Link only on the devices on the network, or ensuring that only a IPv4 DNS server is provided. With IPv6 enabled, it may not be possible to use OpenDNS since OpenDNS is currently an IPv4 product.

I have ASUS router RT-AC56R I used (2620:0:ccc::2 and 2620:0:ccd::2); in the ipv6 dns setti ngs 1 &2 with 3 blank. saved then reset the router not the ipv6 test shows 10/10 and the open dns updater shows yes.

As stated in the post before yours, "IPv6 with content filtering is currently not supported with OpenDNS". If you want to use OpenDNS with IPv6 internet connections you'll have to accept that some portion of your DNS traffic isn't going to be filtered by OpenDNS. If you want OpenDNS to filter all of your DNS traffic then you'll need to turn of your IPv6 internet connection at the router.

If you were asking for something else you'll have to restate what it is that you want because I had a very difficult time understanding what it is that you were writing.

My post should read "I put those ipv6 values in entry 1,2 (there is space for 3 entries) and left 3d space blank, in my routers IPv6 dns area, I then saved the settings and reset the router,. Now (err not) my router tests 10/10 for IPv6 functionali6ty and the Open DNS updater reports Yes (working)"

What is the URL to the router test you are referring to? When say the OpenDNS updater reports it is working are you referring to a specific webpage, or to the updater software you have installed on a computer?

Those two IPv6 DNS addresses are the sandbox addresses OpenDNS announced (https://www.opendns.com/about/press-releases/opendns-announces-ipv6-dns-sandbox-first-available-public-ipv6-recursive-dns-service/ and https://www.opendns.com/about/innovations/ipv6/) a long time ago (2012 I think). At the time they stated that they would only be used to provide recursive DNS service, but not filtering, and when IPv6 filtering is available it will be with a different set of addresses.

If you were referring to the OpenDNS Updater you should be aware that it is only updating your public IPv4 address on your account, it has nothing to do with IPv6, so relying on it regarding your IPv6 traffic would be misleading.

If you go to http://welcome.opendns.com I suspect that you'll get an "Oops, you aren't using OpenDNS yet" message. That's the message I get, and though I'm not using any IPv6 DNS addresses, I still get a 10/10 on the http://www.test-ipv6.com/ page.

A significant portion of my DNS traffic is not being filtered by OpenDNS because the way I have things configured many of my look-ups are going out via IPv6 rather than IPv4. I'm aware of that and accept the loss of protection, but since I want to keep working with an IPv6 internet connection I accept it. You should look closer, but like I said, I suspect if you go to the welcome page you'll get an "Oops" message as well, which leaves you needing to decide between IPv6 and full OpenDNS functionality.

No matter what it should read, you will not be using your dashboard settings as long as you use IPv6 connectivity.
