Optimizing your DNS Server

post #1 of 9
Thread Starter 
In this thread I'd like to help you improve your DNS Server choice in a few simple steps.
I recommend it to everybody who feels like it takes to long to resolve name addresses or is a power user.

What this does and doesn't:
Changing your DNS settings to a different DNS server CAN improve the lookup times for domain names,
making opening NEW pages on the internet faster. However, it will in no way whatsoever affect your bandwidth, download speeds, etc.

Let's get right into it: For benchmarking we will use Namebench to figure out the fastest DNS Server.
Namebench will automatically test available and public DNS Servers such as Googles DNS 8.8.8.8 (8.8.4.4) and OpenDNS 208.67.222.222.

Running Namebench at default settings gave me this result:

Now you can choose your prefered Servers (I recommend picking the second best as an alternate server).

To note: 192.168.178.1 is my router. In my router I can configure my DNS servers manually or use the one from my Internet Service Provider (ISP),
which in my case is the fastest. This will change the DNS Server for ALL your devices using this network.


You can also configure your DNS servers individually for each adapter: Please be aware (Click to show)
that this will then ONLY affect the specific device and that your personal internal addresses e.g. "fritz.box" (my router)
can't be resolved by Googles DNS Service (So put your router as an alternate DNS if you need this or don't know your routers address
and want to connect from this device to it.).
  1. Right click your network icon and get into your Networking Center.
  2. On the left click on adapter settings.
  3. Next click on properties of your Wlan or Ethernet Adapter (in my case I use "Ethernet" to connect to the Internet).
  4. Then select Internetprotocol, IPv4 from the list and then press properties.
  5. Afterwards select "use following DNS" and enter your desired servers.
  6. Finally save your settings by ticking "Test settings after closing" and pressing OK.

I hope this guide will improve your browsing experience and for criticism and suggestions feel free to comment or contact me.


Thanks to coachmark2 for contributing.

Interesting, will give this a try later, see if I'm currently connected to the fastest smile.gif

Good post and lots of good documentation. smile.gif A few notes:

1. Changing your DNS settings to a different DNS server CAN improve the lookup times for domain names, making opening NEW pages on the internet faster. However, it will in no way whatsoever affect your bandwidth, download speeds, etc

2. Setting external DNS servers instead of your router which then forwards it on only changes the DNS settings for your device. it won't affect any other devices on your network. If you want to change it network-wide, you'll need to change the DNS servers for your router.

3. Lookups of internal addresses won't work if your computer is throwing all of its queries at Google or something.

Other public DNS servers include those found here: http://pcsupport.about.com/od/tipstricks/a/free-public-dns-servers.htm

Tell me how it turned out. smile.gif

@coachmark2
Thank you for your good reply biggrin.gif. I agree to your points and I think to people to whom this is new it is important to know. Am I allowed to/should I include your additional information into my post? Or can I link it somehow?

Sure, you can copy/paste it in there. smile.gif But only at your discretion. You are in no way obligated to do so. The information you posted isn't in any way harmful or bad, I was just offering some additional considerations.

I'll have to check this out tonight... I believe my ASUS router doesn't specify a DNS server currently... I'll have to make the switch to say Google and give it a try... We've noticed quite a slowdown on wireless devices since moving to a new place. Maybe this could help?

I would highly suggest running an instance of namebench first, to figure out the best service for you, instead of just using Googles and risk worsening it.
Please tell me if it worked out for you biggrin.gif.

@coachmark2
Have a look at the main post, I updated it.
post #8 of 9
I actually didn't need to change anything... ran the test which took forever...

Google was apparently 43% slower than the current DNS which I had..which I haven't specified..maybe its Comcast, maybe its ASUS? Not really sure...but it said my current DNS is the fastest so no changes needed.

Can't really complain here... I'm actually hoping my Sky Lake build will increase the speed of Chrome and web pages loading... I feel like my 2500k is holding me back even web browsing.

Your processor is more than able to drive chrome. I would check for unnecessary or outdated plugins/addons (Like Flash, Java 32/64...) aswell as deleting temporary files such as Cache/Cookies. I would suggest installing Chrome on your SSD, if you own one.
This should help. Furthermore I would advice you to use piriforms CCleaner to maintain your windows. I can make a Tutorial on how to use this neat tool and do Chrome/Firefox maintenance, if you want to.
