  1. Re:Neither new nor useful on New(?) Anti-Fraud DNS service · · Score: 3, Informative

    So true.

    What happens is nobody has tried the service that's posting this stuff. There's so much misinformation it's hard to know where to start. But I think the best thing I can say is this:

    People at EveryDNS have been using my services for years. We're one of the largest and most free services on the Internet. We've stood up to lawsuits from assholes like Diebold and others in the past in the name of our users. I wouldn't ever scam or do that nasty stuff this thread is saying I would. I have an open email, open door, and open phone policy. I am me, and there's a good amount of clue behind me, and even smarter people around me.

    So when I say this service is not going to spy on you or tell your parent that you look at porn, I'm serious. Read our privacy policy and know that we use the service too.

    Here's the last thing, These can all be preferences. People that don't want typo's caught or other things can have a preference set that gives them just a better and more optimized DNS. When people ask us about our privacy policies I ask you, what does your ISP do? I mean, ATT just said they own all your data and they're being accused of working with the government to spy on you. We don't do that.

    Check it out,

    OpenNIC is a totally different organization. They are an alternate root. We're (OpenDNS.com) not anything close.

    We're about giving you control over your recursive DNS, something you should want. If you don't want us catching typos for you, that's fine. Just check out our FAQ and learn a bit more.

    This POS is neither new nor newsworthy nor useful, at least not for the reasons they try to sell it to you for.

    Well, to be fair, you're responding to the article and not the service. But I'm going to go through and answer each of your points because this post seems to cover a lot of the really important topics.

    An alternative-root DNS system will never work (since Critical Mass is impossible to attain).

    I couldn't agree with you more and we are *NOT* an alternate root. If you are using our service, you are using the real ICANN assigned roots. Period. Full Stop.

    OpenDNS is new particularly because of how we do what we do. We have built a recursive nameservice. That means that we are making the changes only for a client and not for the entire Internet. The article, while good at trying to cover a hard topic, fails to mention that not only are we opt-in but we can set preferences for different users.

    So if you don't want us catching typos, we won't. If you just want straight, normal DNS that's just using a bigger and faster cache, that's just fine by us. We aren't going to mess with you later for deciding that you just want a more reliable DNS. But when you setup your neighbor or mom or brother or friend you might decide they are better off with an added layer of security. The choice is, of course, yours and always will be.

    Myspace will not get faster. Whoever made you believe that is selling snake oil, too.

    First, MySpace is just an example, of course. It does like 10 DNS requests on the homepage loading web,ad,image server FQDNs. But to respond, empirical evidence thus far (from really smart people) would disagree with that statement. Hopefully we'll have some good and more scientifically grounded data soon. If you want to help out with that, let me know.

    In fact, your DNS will actually slow down by a good bit; at least if you belong to the majority of the world (unlike root DNS servers, which actually deliver geographical and network dispersion). The big cache they are so proud of will create lots of problems if they actually do it differently from regular DNS resolver caches that you have at every major (and minor) ISP -- and those will be a lot closer to you than OpenDNS ever will.

    Most resolvers tend to churn through their cache long before TTLs expire so what you're saying isn't exactly true. In many instances most recursive DNS servers toss out a bunch of glue that is consistently being re-fetched. While it's important to respect TTLs (and we absolutely do), it's also important to keep stuff in your cache to get the benefit of the TTL that was set by the zone owner. That's not happening and that's making your DNS not perform well. And it's more than just adding more ram to the system. DNS is 20 years old and it's now a quite critical piece of infrastructure. It's beautiful in many ways, but one way in which it isn't is with how resolvers work. Really, nobody has ever spent much time working on making a killer resolver until recently.

    Fixing typos is a double-edged blade. Sure it's nice if slashdo.torg works. How about whitehouse.gom, though ? And who decides that microsaft.com is really typo-squatter ? (They might just make nice juices !)

    We don't redirect typos like that. We have a ton of requests to do that, but we don't yet for exactly the reason you point out. It's a tough road to go down, and if we do it, it'll be a preference you set with a little checkbox or something. Not a choice I should be making for you. Our goal is to empower you to control what used to be this black box of a memory structure in a DNS server and add some transparency to it for you. That was lost a bit in the article as it focused mostly on the security aspects of our service but there's more; much more.

    Their business model is funny, too.

    Ususally the sites hit were the former home of a spamsite or spammer and at the time of being hit were just the compromised box of an innocent webhost, university computer or other bystander. You can argue all you want about the 1:1 ratio of it, or that networks should be more responsible (I agree) but that doesn't make it right.

    And to the person who said I should suggest something better -- how about a botnet reporting engine to let responsible ISPs know they have compromised machines on their network? Or a system of sifting through whois and domain registration data to determine who the good or bad registrars are out there (like are all phishing sites coming from one policy-loose registrar or not?). Or a system to combat phishing and fraud on the net.

    I can come up with a 100 good ideas to make the net a better place and teach you 1000 things about system administration, networking, running big networks, building scalable systems. Take advantage of that, not of the Internet.

    Being an operator (sysop/netop) is infinitely better than being a hacker. A hacker just needs to know one way into your system, an operator needs to know all the ways in. :-)

    Building software to construct botnets is a totally unproductive use of time. Running botnets that DDoS sites all over the net is illegal. Blue Security isn't out of the woods yet legally and their DDoS of SixApart is far from a closed case.

  9. Re:WikiAds? on Wikipedia Founder Releases Personal Appeal · · Score: 1

    Slavemowgli,

    I understand, completely. I started EveryDNS about five years ago and we are now one of the largest free DNS providers in the world (and likely the most reliable). But growing large and being reliable has its downsides too -- and I suspect wikipedia is facing similar issues. Here's how it breaks down: At the core, it's what we call the tragedy of the commons. As EveryDNS has grown and had more and more users around the world relying on our service they seem to pick up a perception that "wow, there are 78,000 OTHER users, I don't need to donate, the others will." -- This is in stark contrast to what happened with the original 1000 members or so. They had the impression that if they found value in the service I gave them that they should put up money to keep it sustained. Now that is lost, but only slightly.

    That said, I never email my users, so they probably just forget they are even using my service and that they haven't donated in a few years. Hard to say.

    When you serve out a website that pushes in excess of 200,000,000 pageviews a day (yes I really do, dynamic even!) then you start to use a lot of metrics to try to gauge how your code changes and network changes affect things. There are lots of companies that specialize in this sort of thing. This runs from the application level all the way down to the network level, sometimes even the transport layer if you buy their marketing. :-)

    Certainly from the network (RouteScience, Internap, etc) to the application (Zend, Urchin, Webtrends) there are all kinds of companies willing to provide you metrics and solutions, usually at a high cost.

    The trick is to build your own metrics and then find or build the products you need to solve your bottlenecks or improve your user experience.

    Just some ideas, not sure if it is the answer you want.
