Open DNS

post #1 of 18
Thread Starter 
Hi, I was wondering if anyone here has ever used Open DNS. We're looking to impliment it at the company where I work for the phishing and web filtering it offers. I'm just trying to find out how they make their money. I know they show you adds on pages that would have been blocked which means when you request the host name of a site that is blocked then their service actually lies to you and sends you to a different page that is not the actual one that you requested. What is to keep them from doing this more often or using their service for collecting information about where you do most of your browsing. I'm concerned with the security aspects of allowing someone other than your ISP do DNS for you. Any opinions or experiences?

The blocking works great, and their servers are uber fast compared to what my ISP offers. The automatic resolve to search feature is handy too, although it's a bit slow. There are just so many advantages to this free service: DNS shortcuts, all the censorship stuff, and all.. It's pretty cool. And overall, it's super easy to administer.

Go for it.

I've used it for quite a while now and I like it very much. I haven't had any issues at all with misdirections, but that's mostly because I never use the bar. I always use google to find what I need and so OpenDNS is completely transparent to me other than the great speed improvement over my ISP. In my opinion everyone everywhere would do well to assume big brother is watching. I think every company is trying it's best to make the most money with as little effort as possible so it's a safe bet that at all times there is someone watching. Just use common sense and run your firewalls, spywaredetection, antivirus and a nice ip blocker like peerguardian 2. Nothing is perfect but we can make it more of a pain for them.

I've always used them, Qwest DSL's DNS servers take FOREVER to update after I reset my modem, so I switched to OpenDNS and haven't any trouble since.

Why not run phishing and web filtering on your routers?

Hmm, sounds like you've all had good experiences. The thing is, my organization's ISP has pretty fast DNS servers. I'm using the service right now on my local desktop and I'm not noticing any difference in performance between the new servers and the original servers. The main reason we're looking at adopting this service is for the phishing protection as well as content filtering. We don't really care about the advanced filtering abilities just the basic protection. The thing is though, we run multiple domains here as well as have our own mail server. So if our mail server is behind the device that is pointing to openDNS's servers we could potentially have unwanted mail blockage (though i doubt it). One other thing that I don't like is that the way openDNS blocks websites is to essentially lie to my pc about where the particular website i requested is located, it's redirected to their own servers. So my question is, whats to keep them from doing that all the time. In addition at that point they know exactly what I was looking for on the requested page that was blocked. I'd like to know what they do with this information. In addition it concerns me that this company is offering the service for free. Whats to stop them from redirecting me to false websites (other than the fact that they say they don't). Whats to keep their chache from being poisoned by inside personell or people on the outiside. They don't really seem to have a whole lot to lose if somehting like this were to happen as they aren't even charging for the service anyway. What are your opinions, I only ask this because I'm looking at implimenting openDNS for a medium sized organization rather than for home / office use.

I got rid of it after months because I got sick of typing things into the address bar and having it take me to the Open DNS search page instead of the actual site.

Well that wouldn't happen if you typed them correctly in the first place.

OP, OpenDNS isn't going to send you to false websites or do malicious things because then they would lose their reputation and risk going out of business.

I've been using open DNS for the best part of 3 years and not had one issue with advertising or privacy.

How about their cache being poisoned, do you know how often they clear and rebuild it. Also how do domains provided by say dyndns.com work with it. Since those change often is there any way to compensate for this. Would you have to add an exception for it or something.
