    After a lot of testing, I hope to be closer to pinpoint the problem: it seems not like DNS requests fail, but a range of OpenDNS IPs are (ilegally) redirected instead.

    Lately this behavior had changed, as I've got OpenDNS working correctly for the last few months; but now the problem has arised again, without any further explanation from my ISP.

    Example: examining DNS packets, when querying for an inexistent domain name, I got the reply "", which corresponds to OpenDNS. But when I open a TCP connection to and read, I've got the content corresponding to the Speedy advertisment page,

    Any comment regarding if I'm on the right path or if I'm missing the point will be welcome. Any other test you can suggest?

    Note: In Argentina, there is a law (Nr. 26388) passed by Congress and effective since Jun-24-2008, establishing that inappropriately redirecting any communication not addressed to you is a crime; and this is what I'm trying to prove.

    To see if your ISP redirects your DNS traffic post the output of the following command:
    nslookup -type=txt
    (This is for Windows, for others see
    The redirection to could be a different issue though.

    Rotblitz, it sounds to me they are not redirecting his DNS traffic, but his traffic to the OpenDNS block page. In other words, they are quite happy to let OpenDNS do the work, and then they steal OpenDNS revenue.

    Dariox, if they redirect to their own advertising page, you have all the proof you need that they are breaking your new law.

    Yep, that would be the next test:
    If this doesn't return, then they redirect IP address to their advertisement page.
