Exampleadultsite not blocked

December 20, 2020 23:58

My IP address is registered. I've tried from different devices and different browsers. OpenDNS's servers are configured correctly at the router. I do use an IP updater. I'm at a loss. I tried a couple adult sites and they were blocked, but exampleadultsite.com was not. The only reason I discovered this was because I have a specific movie streaming site (not adult) blacklisted and I found my son using it on his phone in spite of the block. So I dug in deeper and discovered this issue. I understand there are plenty of posts about this already, but I've read many of them and none appear to help me. I'm all ears if anyone has any ideas.

Update: I tried again this morning on my Windows 10 laptop. Chrome blocked it. Edge didn't. I tried on my Android phone. Chrome didn't block it. Dolphin did.

Here's the diag info:

C:\WINDOWS\system32>nslookup -type=txt debug.opendns.com.
Server: cdns01.comcast.net
Address: 2001:558:feed::1

opendns.com
primary name server = auth1.opendns.com
responsible mail addr = noc.opendns.com
serial = 1608579345
refresh = 16384 (4 hours 33 mins 4 secs)
retry = 2048 (34 mins 8 secs)
expire = 1048576 (12 days 3 hours 16 mins 16 secs)
default TTL = 2560 (42 mins 40 secs)

C:\WINDOWS\system32>nslookup exampleadultsite.com
Server: cdns01.comcast.net
Address: 2001:558:feed::1

Non-authoritative answer:
Name: exampleadultsite.com
Address: 146.112.255.155

You don’t use OpenDNS, but

Server: cdns01.comcast.net
Address: 2001:558:feed::1

You must configure also IPv6 for OpenDNS.
::ffff:d043:dede ::ffff:d043:dcdc ::ffff:d043:dedc ::ffff:d043:dcde

I entered those settings and it said that server is not valid and it has to be a global unicast address. The first 5 boxes are all 0's and the last 3 boxes are exactly as you provided.

If your device doesn’t accept these addresses or notation variations, then your other option is to disable IPv6 connectivity altogether.

That appears to have done the job. What impact does this have on the internet at my house?

You cannot reach IPv6-only destinations.

Scratch that. Now it's not working consistently. On my Windows computer it blocks in Chrome but not Edge. On my Android phone it blocks on Dolphin but not on Chrome. I'm at a total loss to what's going on and what to do here.

In Chrome you must disable Lite mode and secure DNS.

Else I ran out of ideas. Open a support ticket, link “Submit a request” above.

I submitted a ticket. Refreshing my browser 2 minutes apart can yield different results. So frustrating. Thank you for your help.
