A Quick Way to Change or Check your DNS Setting

A DNS server is that great big internet-based lookup table which turns textual addresses such as google.com into numerical ones such as  Without DNS, you'd have to type those numbers into your browser's address bar, so it's clearly a Good Thing.

But which DNS server does your computer use?  Chances are, you've probably got it configured to use the one provided by your Internet Service Provider.  But there are some other, free alternatives out there too.  Some of them offer additional features, such as deliberately omitting entries for any sites known to host malware, which means that they'll automatically be unreachable if you inadvertently click on a link to such a site. 

Changing the DNS server that your PC uses isn''t particularly difficult.  Just go to the control panel and change the relevant Properties page for the TCP/IP protocol of your network card.  Or, if you prefer, you could use a simple utility program such as DNS Jumper to do it.  DNS Jumper is a handy, free download for Windows XP and above, which you can get from http://www.sordum.com/?p=4573.  The latest version, 1.04, is only a 0.5 MB download, and it's portable so there's no need to install it.  Just download, zip, then click to run.

Not only can you choose from the program's built-in list of free DNS servers, you can also add your own to the list if you know of any that are particularly good.  Plus, there's a facillity to time how long a particular DNS server takes to do a lookup, and you can even automatically set your PC to use whichever DNS server is currently the fastest.

Note, however, that DNS Jumper only changes the DNS server setting for a particular PC.  If you have multiple computers that are connected to the internet via a router, and those machines are configured to pick up their DNS server setting from the router, you may prefer to change the setting on your router instead of each PC.  That way, you can change every machine on your network in one step, whether wired or wireless.  For that, though, you'll need to refer to your router's manual as it's not something that DNS Jumper can do.

We are the developers of the Dns Jumper , Dns jumper is not relevant to Dns changer, and unfortunately Dns Helper's developer (he has stolen the dns Jumper's first version's code , please compare The Dns jumper's first version's release date and Dns helper's first version's release dates) spreading childish lies for example ; Dns Jumper caused him to stopping using the internet , or bluescreen ... (nonsense) Dns Jumper downloaded more than 1.500.000 times and it is the world's first portable virus - free Dns changing App , and v1.0.5 ist the worl's firs Portable IPv6 virus-free dns changing App , till now Nobody Complained like that except dns Helper's developer he try to calumniate our freeware , probably because of the lack of ability to develop better Application
Please use Dns Jumper's latest version (v1.0.5)
Best Regards

An interesting side note. Read the last paragraph of the "Readme" file in the Dns Jumper download from http://www.sordum.org/7952/dns-jumper-v1-0-5/, focusing on the last two words, "Dns Changer". Then look at:


and then google "Dns changer". It's just something I noticed that may have nothing to do with the Dns Changer script mentioned in the Readme, or with Dns Jumper, but it does suggest some questions.

Received to daily e-mail > The current article with the highest user rating at Gizmo's is "A Quick Way to Change or Check your DNS Setting"

The article is 20 months old ,with current available speeds is it likely to be of any use to anyone now ?

by clas on 16. May 2013 - 12:23  (107780)

yes, been using dns helper for years and its always worked fast and easy....tried and true.

On the same topic, Google allows you to route your calls through its own DNS servers. It claims they are faster and more secure. More information's available here: https://developers.google.com/speed/public-dns/

Right - it will update your computer which will override the DNS settings on the router. This can be very handy if, for example, you want to use OpenDNS's kids-safe servers that will block unsafe, porn, etc sites on the kids computer but don't want blocks on the others. (or block all systems from the router but override on one)

Also, if you're wanting to access US-only services (like Hulu) from Canada or Britain, for example, some DNS servers present you as coming from the US, allowing access to those services. (like #22) These however are not fast DNS servers, so its handy to then switch it back to your fast ones after use.

To clarify what I've wrote before,

DNS Jumper works fine. Do flush your DNS with the manual way. Or, using Run command. To ensure that current DNS cleaned or flushed before using the new ones.
From Start Menu:
Start - Run - on the dialog box type "ipconfig /flushdns"
without those " marks.

Thank you for the info and your good works.

This DNS Jumper has been stopping me using the internet for hours. Since I thought it really does do the work whenever I changed the DNS setting. Whereas actually it does nothing but just showing that blue box flashing saying "Please wait..." or something.

I gave another try with my DNS Helper. Now the internet works fine again.

One irritant about this program is that regardless of which DNS I choose, when I fire up the program again, it shows 'Default' instead of the one I had chosen.

As a result, if I fire it up some time during the day, I have no idea which one I had chosen earlier..

by someone (not verified) on 13. March 2011 - 23:14  (67881)

Just do that: Under select Network Card , please choose your Network card instead All network card then you can see which Dns you have ;)

by Janaki (not verified) on 20. February 2011 - 23:23  (66814)

Before selecting a new DNS server you need to run the test a number of times. Run the test at different times of the day. You then choose the one that gives you the best consistent fastest times.

Weekday versus weekend traffic can also make a difference to the results you see.

Please be aware that some DNS servers are very fast but are very easily hackable. It is easy to corrupt popular sites with false addresses that take you to a malware site.

Only go with trusted DNS server names. Do a google search to learn about the DNS server you want to select.

Here in India there are some ultra fast DNS servers that they are testing and tweaking. But due to all this testing and tweaking they are actually very unreliable. Therefore, I stay with OpenDNS, Google and certain production BSNL DNS servers.

They match the criteria I've selected -

* fast
* consistent
* reliable

for choosing a DNS service provider.

Don't forget the Hosts file.
It uses them in sequence so the first valid one is used.

by Burn-IT on 20. February 2011 - 10:53  (66793)

The sequence is that physically followed by the data and it uses the DNS as it comes to them.(remember that software may come first, so that HOSTS file is used first).
It is effectively a branch instruction if a valid target(IE an IP address) is found.

I tried it and chose the fastest DNS Server and I can feel a difference compared to how it was with my internet provider.

One thing though. It changed the IPV4 settings but not the IPV6

Is that normal?



by someone (not verified) on 19. April 2011 - 13:50  (70532)

Its normal because non of the Dns providers support IPv6 yet, such as google :

Does Google Public DNS support IPv6?
Google Public DNS can respond to requests for IPv6 addresses (AAAA requests), but it does not yet support native IPv6 transport and cannot talk to IPv6-only authoritative nameservers. Clients should use IPv4 network connections to use Google Public DNS.

by Chip W (not verified) on 20. February 2011 - 2:52  (66765)

I'm sure changing the DNS server is easy if you know how to do it, but telling us rum dums to go to the Control Panel and figgle with some TCP/IP thing isn't sufficient.
Control Panel > Internet Options or Network Connections? Don't find nothing there.

by MidnightCowboy on 20. February 2011 - 7:04  (66783)

One of the most secure DNS services, and also (according to them) the most frequently updated is ClearCloud. The good news is they provide a utility which installs and does all the configuration changes for you.


One negative is if ClearCloud blocks a site and for some reason you still wish to go there (not recommended), there's no option to do this like there is with say Comodo DNS. You can toggle the service on/off from the tray icon though which reverts to your default DNS settings until you switch ClearCloud back on again. This would enable to to visit a blocked site should you wish to.

Check out also their FAQ about the differences between ClearCloud and OpenDNS.


by pratomorone on 16. May 2013 - 13:47  (107783)

regretfully, clearclouddns has ended their beta period (as of January, 2013).

if you have another such as clearcloud, I would be very eager to test it.

Here's a good utility to compare DNS speeds.

by eikelein on 20. February 2011 - 2:23  (66762)

I played a little with it, nifty.

With only 1ms difference in response time I think I will go with OpenDNS.

Hoping for a reference for an answer to my question below. TIA.

by Dontemailme (not verified) on 20. February 2011 - 3:20  (66768)

This answers your question as well --> http://code.google.com/speed/public-dns/docs/using.html

I'll give it a try.

I have AT&T U-Verse service. The gateway that AT&T gave me has AT&T's DNS servers hardwired, they can not be changed - and sometimes they are so slow that I get time-out errors.

Here my question:

Does the DNS setting in the computer override what the router (gateway) is set to - or does the router setting override the computer setting?

Thank you in advance for enlightening me.

by castiel (not verified) on 22. February 2011 - 1:57  (66896)


Local computer DNS setting will be the one working instead of your ISP gateway hard-coded DNS since it will bypassed the equipment's DNS and go directly to the DNS configured in your local machine. Hope it answer your query.
