OPENDNS is not blocking sites please help

[kean26]

I've configured my PC's DNS to 208.67.222.222 and 208.67.222.220. But opendns is still not blocking sites. I've already flushed my dns and also cleared my browsing data but its still allowing me to access sites that are supposed to be blocked in my settings. I've checked in http://welcome.opendns.com/ and it says welcome to open dns with orange check mark so I know I am realy using opendns. I've typed  nslookup -type=txt debug.opendns.com and got this result

Server: UnKnown
Address: fe80::1

*** UnKnown can't find debug.opendns.com: Non-existent domain

For some reason even disabling ipv6 didn't work so I re enabled ipv6 and put in the provided DNS ipv6 servers and VIOLA! Thank you so much!

I know this is an old post, but trying to make sense on why some devices on the network seem to block the correct things, but not everything. Can I set up the IPV6 DNS numbers on my router? I currently have IPV6 turned off on my only windows machine, and it's turned off on the router, but I just wanted to see about making sure all my Apple devices always route to the correct OpenDNS servers too.

Thanks in advance.
