Blacklisted 4channel.org but still accessible

[hobe8000]

I have blacklisted 4channel.org along with blog.4chan.org & a.4cdn.org.  The latters are blocked but I cannot get 4channel.org to be blocked.

Did you flush your two local caches once after the settings change?

Else copy & paste the complete plain text output of the following diagnostic commands to here:

nslookup -type=txt debug.opendns.com.
nslookup whoami.akamai.net.
nslookup 4channel.org.

Thank you but after doing this on several computers running windows, linux and mac os, the site is still accessible.  I checked DNS records for the site and I have blocked all domains.

Where are the command outputs?

When doing nslookup 4channel.org I get the following results:

user@Desktop-Computer:~$ nslookup 4channel.org
Server: 127.0.0.53
Address: 127.0.0.53#53

Non-authoritative answer:
Name: 4channel.org
Address: 104.17.79.75
Name: 4channel.org
Address: 104.17.78.75

When doing

nslookup -type=txt debug.opendns.com.
nslookup whoami.akamai.net.

The results are fine. There are no authoritative results.

DNS Caches are flushed and have tried accessing 4channel.org on multiple computers and operating systems, yet there is still access even when blocked directly from the OpenDNS panel.

Would the problem be with 4channel.org obfuscating their domain name or IP so that users can access it even under a custom DNS or big-brother situation?

I can’t help without seeing all command outputs.

And no, the problem is not what you think it is.

What exactly is the problem then? I've also blacklisted this site from the panel and followed the steps to flush and it's still accessible. Seems like a GAPING_SECURITY_HOLE
