OpenDNS not blocking on Comcast Business

[aeredrxtrt]

I'm having trouble getting OpenDNS to work. I have Comcast Business class at home and I'm using a D-Link DIR-880L router.

Here's the link to my diagnostic info:

https://diagnostic.opendns.com/d/5195979041013760

 Also when I run

nslookup -type=txt debug.opendns.com.

I get that it's not found.

Can anyone help?

Nobody can help except staff, because your diagnostics results can be accessed by staff only.  Therefore you had to raise a support ticket, or you must post results here, so that other users can help.

Whatever, the "non-existent domain" result you get from the above command indicates that you don't use OpenDNS at all, i.e. you don't send your DNS traffic to OpenDNS.

To ensure that your DNS traffic is not hi-jacked by Comcast or otherwise, execute the following command:

nslookup -type=txt which.opendns.com. 208.67.220.220

If this returns "I am not an OpenDNS resolver", then your DNS traffic is hi-jacked, whereas if it returns something like "9.abc", then you didn't configure the OpenDNS resolver addresses correctly on your router and need to correct it.

Hi,

Thanks for running the Diagnostic Tool. Base on the results, everything seems to be set up correctly and you are using OpenDNS.
