OpenDNS no longer working

[psimmond]

When I go to http://welcome.opendns.com I get the Oops page that says I'm not using OpenDNS.
I have it configured in my router:

IPV6 is disabled

In my Dashboard, my "current IP" matches my Settings:

I did see that my updater doesn't show IP address (see image below). Is this normal?

• I cleared browser cache
• flushed DNS
• rebooted computer
• rebooted router

I don't know why but it just started working!

Well, it seemed to work for about a minute, I got a checkmark on that Welcome page, but now it's back to Oops.

You‘re clearly using Charter‘s DNSv6 service, not OpenDNS. I suggest you configure IPv6 with DNS addresses from this list:
::ffff:d043:dedc ::ffff:d043:dcde ::ffff:d043:dede ::ffff:d043:dcdc

[psimmond]

Strange! I just checked router settings and IPV6 was "Enabled." Is it better to disable it, or to use 2 of the addresses from the list you just gave me? (I thought I read somewhere that it was better to disable it if using OpenDNS.)

[rotblitz]

If these addresses work for you, then this is the better option than to disable IPv6. Disabling IPv6 causes that you cannot reach IPv6-only sites and that your Internet may be slower.

I tried the first 2 together and it didn't work, I tried the second 2 together and it still didn't work, so I went back to "Disable." Thanks so much for helping!
