Having an issue with using OpenDNS with my desktop PC.

[mister-jay]

I tried to send a message to the OpenDNS support, but nobody has messaged me back. Apparently i have got OpenDNS for my laptop to work, but i can't get it to work on my desktop I followed the setup instructions for Windows 10 like i did with my Laptop, but it didn't work after following instructions. I've got the desktop wired into a Netgear EX7000 Wifi Extender since the router is in the basement. Is there any other information that you will need?

You don't say how or when you sent this message to support, but for OpenDNS Home they have been saying it can take 3 business days for an initial response, longer if they are dealing with a lot of issues. Not ideal, but it is a free product after all.

As for information you can provide, you could start with what you mean by it not working. Is this desktop using the same connection to the internet as your laptop? What happens when you visit https://welcome.opendns.com/ ?

Also, copy & paste the complete plain text output of the following diagnostic commands from your desktop to here:

nslookup -type=txt debug.opendns.com.
nslookup whoami.akamai.net.
netsh interface ipv4 show config

The message was sent over two weeks ago. And by what i mean by OpenDNS Isn't working on my desktop pc, is that after following the necessary steps for setting up OpenDNS Updater on my desktop it is not running or blocking any websites. When i visit the link you sent me , it says:

Oops!

You aren't using OpenDNS yet. Let's fix that

If you haven't restared your computer yet, please do that now.

I'm running both computers off the same connection, only difference is the laptop is running wirelessly from the extender and the desktop is wired to it.

Some, or all, of your problem is that you're sending your DNS traffic out via IPv6 to Comcast DNS servers and it's not even reaching OpenDNS.

You need to disable IPv6 at (preferably) the router level or worst case you can disable IPv6 on your computer. There are "alternative" IPv6 OpenDNS addresses that you can use along with the regular one, but I don't advise anyone to use them because I don't currently have an IPv6 connection and can't test it for myself.

One other thing, it sounds like you are running the Updater from both your laptop and desktop. You only need to (and should only) run it from one device on your network, Running an updater from multiple devices not only is unnecessary, but can actually cause problems and conflicts.

As mattwilson9090 said, this is where your DNS traffic goes, clearly not OpenDNS.

Try with configuring ::ffff:d043:dedc and ::ffff:d043:dcde as DNSv6 server addresses either on your computer or on your router.  It works for me and my dual-stack (IPv4 and IPv6) internet connection.  Else disable IPv6 connectivity.

"Running an updater from multiple devices ... can actually cause problems and conflicts."

I disagree.  ;-)
But it's indeed not ideal to run the Updater from multiple devices unless only one device is switched on and the user being logged in to it at most times.  (Prerequisites for updates to function with this Updater.)
