Cannot find the issue with setup on a Comcast / Dlink DIR860L connection
I really have read many, many posts in this forum on the issues with routers and setup.
I have a Comcast RCA internet&phone connection - it's internal DNS settings are:
RCA DHG536G 75.75.76.76 / 75.75.75.75
We have a new DLink DIR860L router connected to the Comcast unit.
I have done the OpenDNS setup with 208.67.222.222 / 208.67.220.220 There are only two DNS entry spaces. It looks just like the example for the Dlink 855 on the OpenDNS router setup page.
I also already flushed my dns cache, based on the website instructions. ipconfig /flushdns
I also cleared my browser cache.
I have restarted all devices.
Right now on my iphone it shows all four DNS entries 208.67.222.222 / 208.67.220.220 / 75.75.76.76 / 75.75.75.75
When I check the OpenDNS updater it shows "No, Learn how to setup at ....."
The result of nslookup -type=txt debug.opendns.com
C:\Windows\system32>nslookup -type=txt debug.opendns.com
Server: resolver1.opendns.com
Address: 208.67.222.222
*** resolver1.opendns.com can't find debug.opendns.com: Non-existent domain

If this is your manual, then you would configure the resolver addresses in the DNS fields as from page 27 on. If you still see other non-OpenDNS resolver addresses, then these may be hardcoded in the end devices, or your router firmware has a bug. Try with the latest firmware then or contact D-Link support.
Before you take any efforts regarding your router, ensure that your ISP does not redirect your DNS queries:
nslookup -type=txt which.opendns.com. 208.67.220.220If they do, your router settings will not take effect.

I did reboot and reset the Comcast device.
I am not sure why however, we are now working, filtering pages and have a "yes" on the OpenDNS updater.
I ran "nslookup -type=txt which.opendns.com. 208.67.220.220"
C:\Windows\system32>nslookup -type=txt which.opendns.com. 208.67.220.220
Server: resolver2.opendns.com
Address: 208.67.220.220Non-authoritative answer:
which.opendns.com text ="11.ash"
So for the moment we seem to be OK.
Thank you

And now 10 min later we are down.
Still connected to the internet but when at http://www.opendns.com/welcome/ i get the "Oops" page.
Nothing was changed or reset or off and on.

You can use OpenDNS, and your ISP doesn't redirect your DNS queries.

75.75.75.75Yes, beside OpenDNS' you're also using Comcast's DNS servers. As I initially said "your router firmware has a bug. Try with the latest firmware then or contact D-Link support" if you got the router from them. If you got it from Comcast, they may have amended it this way, and you have to contact them, or you may be able to overcome this by flashing the router with D-Link's OEM firmware.

Thanks for the feedback so far.
Some newb questions...
The Dlink DIR860L is a brand new router I purchased with the newest firmware (ver. 1.04) on the site they only offer up to ver. 1.03.
The RCA DHG536G is the Comcast device that is adding the 75.75.76.76 / 75.75.75.75.
I called Comcast and there was no interface that allows me to change the DNS entries.
I might have to buy my own cable modem to gain access to all the DNS entry areas within our connections?

Well, you could start to configure the OpenDNS resolver addresses also on the computers:
https://store.opendns.com/setup/computer/
This would remove the Comcast addresses at least from these computers.Also, you could try to downgrade the D-Link firmware to v1.03 or earlier to see if this helps.
Or you try to tweak your cable modem in some way:

It is a Thompson device, so the Thompson website may provide firmware and other stuff for it. -
Same issue here. DIR-860L. IPCONFIG/all shows 4 DNS servers. First 2 are OpenDNS the next 2 are Comcast DNS. http://www.opendns.com/welcome/ returns Oops.
Firmware Version : 1.05
