Free DNS Jumper – Easily Change Your Default DNS Settings

Popular guest writer Rick Robinette, has a knack for finding great free applications – applications that make the Internet experience smoother, safer and more interesting. See what Rick has to say about his most recent find – DNS Jumper.

If you are a regular reader of the blog (What’s On My PC), you may have read the following articles about DNS (Domain Name System) and how changing your default DNS settings on your PC to a service such as OpenDNS or Google’s Public DNS can result in a faster (and safer) internet experience. For example I use the DNS settings that is provided by OpenDNS on all of my computers.

OpenDNS … Something to try…

Google’s Public DNS Resolution Service

The DNS protocol is an important part of the web’s infrastructure, serving as the Internet’s phone book: every time you visit a website, your computer performs a DNS lookup. Complex pages often require multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day. – Google Public DNS

When I composed those articles, I wondered how many people actually followed up and changed their DNS settings, for fear they would mess up their computers?

Today, I ran across a small software utility called DNS Jumper that you simply download, run, and mouse click a button to select which DNS service you would like to use.

This little utility does all the work for you. If you desire to return to your default DNS settings, you simply mouse click on DNS Default and your settings revert to the original settings. This utility is portable and makes for a nice addition to the tech toolbox.

Note: A beta version (DNS Jumper v1.0.3), is also available. Keep in mind however, that a Beta version is not necessarily a stable release.

    Thanks Rick, and Bill.

    I’m always looking for ways to be safer on the internet.

    Good article.

  5. Okay Rick and Bill, this tool is just plain cool, and very useful. Thanks very much. So here’s a tool that lets you check out your currant DNS and see if services like Google DNS or my favorite Open DNS will benefit you. Its from the illustrious Steve Gibson.
    Thanks again.

      Hey Mark,

      Gottta love Steve Gibson. – so many great service and apps. This one, you’ve just pointed, out is definitely one of the best. This is one I was not aware of, and I thank you for that. I’ve just been running and playing with it, and it’s VERY cool! It showed me that my ISP’s primary DNS, the one I have set, is in fact, slower than the second one in line (out of 4) – so I’ll make that change right away.

      There’s an article in this for you, and I’d LOVE to run it. If you have a chance, that would be very cool.

    Oh Bill you have become a favorite site Of the nerd side of me :^) Keep up the good work!

    • Bill Mullins

      Hey Rose,

      How very nice of you to say so. You just made my day, and more!

      I do have a Twitter account, I’m just too blasted lazy to do much with it. I’m really just an accidental blogger, who VERY accidentally has been lucky in attracting some of the most technically astute, and personally charming people on the Internet, as loyal readers. People like you.

      My field is system and Internet security, so my ranting about it (and I do rant occasionally from my soapbox), in a Blog, is just a natural offshoot.

      BTW, I dropped by you site, and your Twitter page (I’m a very curious person), and I must say; you are a very strong and interesting woman. I have a great fondness for strong and interesting people.

      Please drop by often – it’s people like you, who are the “fun” factor in blogging.

    BTW are you on twitter?

    Also you may like to check out Steve Gibson’s DNS Nameserver Spoofability Test which has some very interesting info on at

    I just ran the DNS Jumper programme and according to Steve’s DNS test the server that DNS Jumper assigned to me as being the fasted was actually dead and it was using my secondary DNS.

    So I’m sorta trying to figure this one out still. But as per usual very useful and helpful information.

    I’ll be glad when I’m back at school so I have to concentrate on my studies rather than spending soo much time downloading all this great software. 🙂

      Hey John,

      You’re right – taking Gibson’s DNS Nameserver Spoofability Test is very worthwhile.

      Let me know if you figure out the problem.

      You guys are pretty lucky down under with your Summer in full bloom. I’m freezing my butt off up here in Canada, and we still have a month or two to go before Spring!

    I found you and added you on twitter

    Gee Bill,
    Don’t you ever sleep, and sorry this is a long one! 🙂

    Yes we are very much at the height of summer at the moment and we can expect it for at least another couple of months, me I’ll be extremely glad when things cool down a bit.

    You’re in Toronto, yes? I remember being there just after the 76 Olympic games in Montreal. The CN tower had just been built and there was some hoo haa about an ice hokey game between Canada,Ussr, and the Usa if I remember correctly. I do recall that there was huge excitement at the time.

    Getting back to Grc’s DNS benchmark test it has told me that I have several issues with my router.

    “X System has only ONE (router based) nameserver configured.
    It appears that only one local (router gateway) DNS nameserver, with the IP address of [], is currently providing all DNS name resolution services to this system. This configuration is not recommended because most consumer-grade routers provide inefficient and under-powered DNS resolution services.

    Unless the DNS resolvers your router is using is under your control, it may not be providing the best or complete name resolution services. For example, is it using multiple redundant DNS nameservers?

    Recommended Actions:

    Unless you have some specific reason not to, you should give serious thought to disabling your router’s provisioning of DNS services (which it is providing for all computers on your local network). After this is done, a fresh reboot of your computers will likely reveal the multiple DNS nameservers provided by your ISP. This is a superior configuration, without an under-powered router acting as a incompetent middleman and impeding all DNS access.

    Note that if you can determine the IP addresses of your ISP-provided nameservers (which may be visible in your router’s web configuration) you could manually add them to the nameservers being tested by this benchmark, while also leaving your router providing DNS. This would allow you to compare the performance when running through your router versus “going direct”.

    X One or more system nameservers is NOT 100% reliable!
    DNS reliability is extremely important, since lookup requests that are dropped and ignored by nameservers cause significant delays in Internet access while the querying system waits for a reply. The system is then finally forced to reissue the query to the same or to backup nameservers. While your system is patiently waiting for a reply, you are impatiently waiting to get on with your Internet access.

    During this benchmark test, the nameserver being tested did not reply to some of the DNS queries it was sent.

    So the question now is: Did the benchmark discover alternative nameservers having superior performance and reliability to which you could switch in order to obtain more performance and reliability?

    Recommended Actions:

    Before you make any changes, you should probably run the benchmark a few more times at differing times of day to make sure that the troubling reliability is an ongoing problem and not just a brief occurrence.

    You may also wish to consult the “Tabular Data” page which summarises all benchmark results in numeric tables. The numbers make it easier to see exactly how unreliable your system’s nameserver is compared with the available alternatives. (And also how the alternatives’ performance compares.)

    Well that is about all the problems I encountered, what does it all mean and can I rectify it myself?……… I doubt it, it’s starting to get into unknown territory for me.


    PS I very much enjoy the information that you provide for all of us readers.

  11. Hi Bill

    I switched to OpenDNS a while back. It was a tricky operation as there was no easy way to switch my router so that any wifi-connected devices would take the same route. I ran Steve Gibson’s tool when he announced it on his Security Now podcast, and OpenDNS’ performance was good enough. I’m sticking with it because it also gives me additional control options via their dashboard.

    Wow! This is a new tool sir Bill. A easy to configure DNS. Usually before changing DNS, I run DNS Bench from to get the fastest dns in my area. And then I change it manually. But this one is just a few click and ready to go.
