Comcast DNS Redirection Launched In Trial Markets

An anonymous reader writes "Comcast has finally launched its DNS Redirector service in trial markets (Arizona, Colorado, New Mexico, Oregon, Texas, Utah, and Washington state), and has submitted a working draft of the technology to the IETF for review. Comcast customers can opt-out from the service by providing their account username and cable modem MAC address. Customers in trial areas using 'old' Comcast DNS servers, or non-Comcast DNS servers, should not be affected by this. This deployment comes after many previous ISPs, like DSLExtreme, were forced to pull the plug on such efforts as a result of customer disapproval/retaliation. Some may remember when VeriSign tried this back in 2003, where it also failed."

    Some may remember when VeriSign tried this back in 2003, where it also failed.

    Oh yeah, way back in the day. But let us not forget Earthlink's attempt at this or Canadian Rogers Cable or Charter or NJ Cabelvision or ... I'm sure you could find no end to this stream of providers offering their customers something the customers simply do not want.

    And I'm pretty certain most of those ended or resulted in customers bitching out the provider. Yet here we go again. Why? Well, that's simple: ad revenue.

      If I'm not mistaken (although I often am, sorry in advance) Cox has been doing this for months now, and nobody posted anything about that. If I 'typo' a URL at home, when connected via my (or my neighbor's) Cox cablemodem, I get a Verisign page indicating that www.whateveriswas.com is Under Construction.

      Is this not muchly the same thing??

      To "opt-out" all you have to do is change the last octet of the DNS servers they supply to you to 14. So if Verizon default DNS server is 123.123.123.12 change it to 123.123.123.14.

      No, you threaten to sue them for lost company profits caused by their DNS hijacking and interfering with your work routine, and that you can 100% prove it and have documented everything relevant. That'll get you out of your contract in a hurry.

      I just used that to help a motor sports company out here in CA get out of their contract with Comcast.

    OpenDNS does the exact same thing. To avoid DNS highjacking if you use OpenDNS, you have to have an account with them, change your preferences and always be identifiable to OpenDNS so that it can apply your preferences. It's easier to opt out at Comcast than to opt out at OpenDNS. Besides, OpenDNS also redirects www.google.com to OpenDNS servers, not just nonexistent domains.

    According to the fine article there's an opt-out button on the page you get redirected to so I'm not certain that would be necessary:

    We also understand that sometimes customers want to surf their own way, without the assistance of services like Domain Helper, so we offer an easy way to opt-out right on the Domain Helper search page.

    It doesnt redirect you to another 3rd party site owned by the NSA, it simply provides a web GUI that suggest sites on what the system thought you wanted to see.

    It doesn't redirect you to a third-party site owned by the NSA; it redirects you to a third-party site, full stop. This not only breaks a whole host of applications relying on DNS to inform them that a domain name doesn't exist, but it is in violation of the standards that hold the Internet together.

    Why do these OpenDNS posts keep getting modded up? OpenDNS utilizes the very practices this article bemoans! If you query a domain that does not exist, your browser is redirected to OpenDNS's ad-laden spam site.

    Despite their claims to the contrary, OpenDNS's servers are likely farther away from you than your local ISP's. They also keep permanent logs of all queries, which could be subpoenaed by a government entity. Their joke of a privacy policy allows them to sell your logs to "Affiliated Businesses", which pretty much means anybody. Not that it really matters - they could amend their privacy policy tomorrow morning and be selling your info by the afternoon.

    I think many people read the "Open" part of the OpenDNS name and turn their brains off.

    In what way is this relevant to OpenDNS? They actually do the same dirty trick aswell. Just because they have "open" in their name doesn't mean they're great and everyone should use them. They run their DNS servers to make profit from non-existing domains and hell, they even redirect requests to google.com to their own servers.

    Thankfully there are open dns servers that dont do such either, for example university in Gothenburg, Sweden: 129.16.1.53 and 129.16.2.53 and several others. Those that have the technical knowledge can also set up their own dns recursive dns servers on their linux box and use those directly (while it fetches the results from root servers)

    Easy, through innovation and distinct added value. Shouldn't take a rocket scientist to figure it out but apparently it does. Recently, our ISP decided to offer a brand new service allowing you to double your bandwidth simply by adding another DSL line. Guess what, they are now the fastest growing ISP in Canada.

    Schemes like DNS redirection are a scam and should be banned unless they contain no advertising or indirect revenue generation whatsoever.

    Try looking at the entire service. So far as I have been able to tell, you can turn off every single one of their "features", giving you a simple, straightforward dns service.

    And for those replying to you confused about the google thing - they don't

    redirect requests to google.com to their own servers

    . What they do is provide a dns entry for www.google.com that points to their own servers. These servers proxy the real www.google.com to strip out some functionality that opendns found particularly offensive (I have not experienced the functionality, and can't say whether I agree or disagree with their views). However, like every other "feature" I've found at OpenDNS, you can turn this off. Yes, at first you couldn't. I stopped using OpenDNS for awhile. Now you can.
