Charter Implements SiteFinder-Like DNS 206

paulbiz writes "Charter Cable's DNS servers have just started resolving all invalid hostnames and pointing them to their own error page. The About page states: 'This service automatically eliminates many of the error pages you may encounter as you surf the web. No software was installed on your computer for this service to work.' It has an 'opt-out' page, but when you use it Charter simply sets a cookie that makes their page redirect errors to Microsoft Live Search instead!" One more reason to use OpenDNS, where you can actually opt out of the custom error page.

      I run my own resolver, too. In fact everyone runs their own resolver. The resolver is the bit of the DNS infrastructure that runs on client machines and is responsible for performing lookups. Every computer that can access the Internet tubes has a resolver on it.

        Not true! When I got my sun3/260 (long since gone, although I did upgrade it to a 4/260 while I still had it) I installed SunOS 4.1.1 on it, as it was the latest and greatest that you could even get on there. It came with TCP/IP but the resolver was not linked in! I actually had to link the DNS resolver into libc (IIRC) before I could use DNS. But I could still access things by IP, and actually did so.

Last time I checked, they were just as bad as ever. I've pointed several friends to OpenDNS and they were all amazed at the difference. Charter's customer server is horrendous and the only reason they have a market lead in this area is because they have exclusive service in so many apartments and subdivisions.

    Of course, if you're running your own BIND server on your NATted network, which forwards non-local queries to the upstream DNSs, you can use something like what ISC recommends in case of SiteFinder. In /etc/named.conf:

    zone "COM" {type delegation-only; };
    zone "NET" {type delegation-only; };

He had no idea this was going on, and rightfully thought it was a malware/spyware problem at first, until I explained a little more clearly what was going on, and he did some poking around and found other blog and forum posts about this. He seemed somewhat surprised that Charter would engage in such a practice and that no one had been told about it.

    He was talking with level 2 support while he was on with me and said that they just kept telling him it was probably malware/spyware. Hilarious that they at least see it that way too, but sad that their company pulls this shit on them without telling anyone first. I asked him for a followup, he said he'd pass it along to level 2, I gave him my email address, and that was that.

    - Will they provide options for customers who don't allow or regularly clear cookies, such as a non-redirecting DNS?

    I'm not surprised ISPs are doing this. More will be doing this. What does surprise me is how ISPs try to do this silently and behind closed-door without informing their customers, or even their tech support in some cases.

    Think about it this way: Any change an ISP makes that results in 1% (or more) of their customer base calling in for technical support is a cost nightmare. Customer Service is a (*the*) major cost center for ISPs. I guess we have to imagine that they are making more money than the pain of doing the customer service is costing them.

    The other thing that surprises me (and obviously I'm biased since I run OpenDNS) is that the search results page linked above is 100% ad-driven. There are no no organic search results for my typo (as far as I can tell). Moreover, when I click on a category to "refine" my results they totally remove the typo'd domain that I had there in the first place instead just giving me generic ads for a category (which is a mediocre CPC on their side) and a crappy search experience on the user side. There is absolutely no user-benefit to what Charter has done here.

    I'm proud to say that our page [] is getting better and better every single day. Compare [] and contrast []. Not only that, but we're driving more and more innovation in both user navigation and fundamental DNS operations. These things go hand in hand. Fundamentally the DNS is about navigation. It's about helping users get where they are trying to go. That's exactly what we intend to help our users do. We know that the changes we have made to how our DNS servers operate aren't for every user which is why we are so clear about how our system works and is why make sure we can manage account settings on a per IP basis (CIDR-style preferences down to /32's).

    As usual, I'm happy to answer questions where I can.

  • Just how does a DNS error page work? Is this a specially crafted UDP packet on port 53? Don't think I've seen one of them. Returning the IP of a charter http server instead of NXDOMAIN for non resolvable domains is NOT a DNS error page (FFS). And thats the problem, its DNS and it should return a DNS error. TCP/IP is not the intraweb. HTML infomercials don't help one iota when you've mistyped a hostname into anything other than a web browser, whereas NXDOMAIN does.
