      This is nothing more than another attempt to make some money off of the basic infrastructure of the Internet. DNS is free right now. And to some people, that means that there is a chance to "monetize" that service.

      As far as I know, the DNS resolution has never been the problem for MySpace loading slowly. It's slow because so many other people are hitting their servers and bandwidth. And since Win2K, Microsoft has included a caching DNS app so once you do hit MySpace, you've cached the address on your workstation. You can't get much faster than that.

      Here is how the faster claim works. Say there is a 150ms round trip between you and your ISP's name server. You computer requests the IP for www.slashdot.org. If you are lucky then www.slashdot.org is in the name server's RAM cache, and you get a fast response in just a little over 150ms. If not (and for the majority of websites, its not) then the name server has to search its disk cache (this is where it is most likely to be. If its still not found, then your ISP's server has to look up slashdot.org with the root servers, and get the name server for that domain, and next it has query the dns server for slashdot.org to find the machine named www. each of these taking more time.

      I presume what they do is have machines with loads of RAM (how many dns entries could you keep in say 4GB anyway?) and try to serve as many requests as possible from a RAM cache rather than disk cache. Thats my guess anyway.

      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.

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.

    The dns repsonse is the same as the ping so they will never get faster then my isp.

    I can understand why slashdot geeks wouldn't want their DNS servers messed with, I'm among you, however most of the internet users out there aren't nearly as computer literate as we are, and this service I believe would be really good for them. Netcraft has been trying to fight the good fight against phishing and scamming sites for a long time, and here's a group of guys who are really blocking them at the source.

    I applaud their efforts, while it may not be for me, I think a lot of people are going to find it very useful.

      Most internet users don't know or care what a DNS server is. For this to succeed you need to capture the hearts and minds of the ISPs. Luckily for them, ISPs are very concerned about DNS right now as it is critical, somewhat vulnerable, and they are lacking visibility into it. Unluckily for them, the entrenched players have all started jumping on this and providing real solutions. Why block all requests to a DNS name when legitimate researchers and security people might need to get there? What about when a cracked server that still hosts legitimate content as well? what about when the FQD is a forum with 99% legitimate traffic and 1% worms and phishing?

      This solution is a shotgun where a scalpel is needed. Block worm traffic as detected by the DNS request, not all traffic to that domain. Also, contrary to what people seem to be thinking here, the main DNS issue is not worms or phishing (ISPs don't care that much) but they do care about large chunks of their traffic to the DNS servers coming from misconfigured servers repeatedly querying them. Since, in many cases, these servers are their own, blocking them with a fancy, broken DNS server is not the best plan. Redirecting other ISPs' server to an ad a million times a day will not yield any long-term profit (since no person sees them) Rather, fixing their own servers and notifying others/filtering at the peering edge is the way to go. Since ISPs are now able to do that, I foresee a large yawn when operators see OpenDNS (what a misleading name, kind of like OpenXML).

    Personally, I have one word: Next.
  • Sites can periodically change their IPs. Is some kind of testing included in the caching app that makes sure that the cached IP numbers still work? And, even if the testing is periodic, will sites that change their IP numbers be broken longer than the usual propagation time of changes?

    And they'dk *better* not cache *.homeip.net and *.dyndns.com.....

    -b.

    • *All* recursive DNS servers/resolvers do caching. They also obey something called 'TTL' for records when doing so, and dynamic-IP services such as those you refer to set a suitably short TTL so as to cause caching to expire appropriately.

      That they cache data isn't really that noteworthy, its more them calling attention to it in their marketing more than anything else. Perhaps they have configured their servers to support a very large cache, so that it doesnt have to delete anything until the TTL does call f
      • Really the more useful part of this (for the average used) would be the blocking of known phish sites and/or typo correction, than the caching. And to be honest, I don't see that greate a value in it.

        Nor I. AFA phish scams, I type the (bank or whatever) site name into the browser myself - I don't click on links asking for account information in emails. Typo correction? What's the big deal about getting an error message that the named site doesn't exist and for you to reenter the name? What if you were

    FTFA: "Those who click on a link in a phishing e-mail that attempts to take them to a fake site and con them into entering their credit card number won't even make it to the website, if OpenDNS knows about it."

    A false sense of security is worse than no security at all. "if OpenDNS knows about it" indeed ... so when can the user trust that OpenDNS has successfully caught the phishing attempt, and when should they check that it has failed? The answer is simple; they should perform the same checks WITH OpenDNS as without, except now there will be a whole raft of users who don't know that and the phishing will get worse.

    I'm sorry. When I think of system I think of daemons. Improvements to the DNS system would be appreciated. Someone to provide me with commercialized redirections and pay per use DNS service doesn't equate to improvement.

    Sites providing free email without protecting their URIz with spf protection is what needs to be fixed. This would help to kill spammers pretending to be google, yahoo, aol, et al.

    Your company advocates a

    (*) technical ( ) legislative ( ) market-based ( ) vigilante

    approach to fighting spam. Your idea will not work. Here is why it won't work. (One or more of the following may apply to your particular idea, and it may have other flaws which used to vary from state to state before a bad federal law was passed.)

    ( ) Spammers can easily use it to harvest email addresses
    ( ) Mailing lists and other legitimate email uses would be affected
    ( ) No one will be able to find the guy or collect the money
    ( ) It is defenseless against brute force attacks
    (x) It will stop spam for two weeks and then we'll be stuck with it
    ( ) Users of email will not put up with it
    ( ) Microsoft will not put up with it
    ( ) The police will not put up with it
    ( ) Requires too much cooperation from spammers
    (x) Requires immediate total cooperation from everybody at once
    ( ) Many email users cannot afford to lose business or alienate potential employers
    ( ) Spammers don't care about invalid addresses in their lists
    ( ) Anyone could anonymously destroy anyone else's career or business

    Specifically, your plan fails to account for

    ( ) Laws expressly prohibiting it
    ( ) Lack of centrally controlling authority for email
    ( ) Open relays in foreign countries
    ( ) Ease of searching tiny alphanumeric address space of all email addresses
    ( ) Asshats
    ( ) Jurisdictional problems
    ( ) Unpopularity of weird new taxes
    ( ) Public reluctance to accept weird new forms of money
    ( ) Huge existing software investment in SMTP
    ( ) Susceptibility of protocols other than SMTP to attack
    ( ) Willingness of users to install OS patches received by email
    (x) Armies of worm riddled broadband-connected Windows boxes
    ( ) Eternal arms race involved in all filtering approaches
    ( ) Extreme profitability of spam
    ( ) Joe jobs and/or identity theft
    ( ) Technically illiterate politicians
    ( ) Extreme stupidity on the part of people who do business with spammers
    ( ) Extreme stupidity on the part of people who do business with Microsoft
    ( ) Extreme stupidity on the part of people who do business with Yahoo
    ( ) Dishonesty on the part of spammers themselves
    ( ) Bandwidth costs that are unaffected by client filtering
    ( ) Outlook

    and the following philosophical objections may also apply:

    ( ) Ideas similar to yours are easy to come up with, yet none have ever been shown practical
    ( ) Any scheme based on opt-out is unacceptable
    ( ) SMTP headers should not be the subject of legislation
    (x) Blacklists suck
    ( ) Whitelists suck
    ( ) We should be able to talk about Viagra without being censored
    ( ) Countermeasures should not involve wire fraud or credit card fraud
    ( ) Countermeasures should not involve sabotage of public networks
    ( ) Countermeasures must work if phased in gradually
    ( ) Sending email should be free
    (x) Why should we have to trust you and your servers?
    ( ) Incompatiblity with open source or open source licenses
    ( ) Feel-good measures do nothing to solve the problem
    ( ) Temporary/one-time email addresses are cumbersome
    ( ) I don't want the government reading my email
    ( ) Killing them that way is not slow and painful enough

    Furthermore, this is what I think about you:

    (x) Sorry dude, but I don't think it would work.
    ( ) This is a stupid idea, and you're a stupid company for suggesting it.
