Dns Benchmark Mac Oleh Anonim Maret 22, 2020 Posting Komentar How To Choose The Best And Fastest Alternative Dns Server.
Updated February 2021. DNS or Domain Name System look-ups play a huge role in defining how fast your broadband connection really is with ‘real world’ applications such as browsing. In this article, we’ll be show you how to speed up DNS look-ups easily and for free by choosing the best and fastest DNS server(s) for your particular broadband connection. For more tips and guides in improving your broadband, visit our Increase Broadband Speed Guide.
- Feb 11, 2017 If you've got a speedy internet connection at home, but it seems slow, it's possible its' not the connection itself but the speed of your chosen DNS server. To figure out if the DNS servers are part of the problem, check out namebench, a DNS server benchmarking app. Namebench compares your existing DNS servers to a large list of other DNS servers, and shows you how they all perform.
- Download DNS Benchmark for Windows to determine the exact performance of local and remote DNS nameservers.
Aug 30, 2017 Follow these instructions to use DNS Benchmark for finding the best DNS server: 1. Visit the DNS Benchmark download page, scroll down and download DNSBench.exe (download by clicking Download Now, or by clicking the image above or the self-explanatory link below it): 2. GRC provides a simple three-step guide for using the basic benchmarking.
What is the Domain Name System (DNS)?
The Domain Name System is the mechanism by which meaningful website domain names (such as google.com or facebook.com) are translated into the IP addresses (for example, 212.58.244.26 and 74.125.129.94) of the servers providing these websites. All web servers are assigned an IP address, which is a numerical label that is used to identify them and which enables them to be found on the Internet.
While the IP addressing system is a very useful identification mechanism for computer devices, it is not a particularly human-friendly means of identification. A domain name (for example, www.google.com) is essentially a human-friendly version of an IP address.
Not only is a domain name easier for people to remember, but a domain name provides flexibility in terms of how websites are accessed on the Internet. For example, Facebook could decide to change the server providing its web pages (and, therefore, its IP address) without needing to change the domain name.
DNS look-ups create a delay
When you enter a domain name into your browser or you click a particular link, it is necessary to first translate the name into a numerical IP address so that the contents of the website can be retrieved. This process inevitably causes a delay in the web page being rendered although, through optimisation, this delay can be minimised.
A distributed database architecture is used with the Domain Name System, with many DNS servers located across the world to allow domain names to be translated to IP addresses for all devices is existence, despite many changes in IP addresses being made every single day.
It would be impractical to have a single DNS server providing the translation of domain names to IP addresses for all Internet users in the world since a single server would soon get congested by all the DNS look-ups being undertaken. Also, broadband users located a significant distance from the server would suffer from large time delays.
Many ISPs run their own DNS servers to provide domain name to IP address translation for their broadband users. In addition, a number of third parties (such as Google, Cloudflare and OpenDNS) provide independent, so-called “Public” DNS servers.

In general, most routers supplied by ISPs are set up to use the DNS servers operated by the ISP. Office tab for mac os. This means that your browsing experience is determined in part by the performance, reliability and location of your ISP’s DNS servers.
If your ISP’s DNS servers are unreliable or slow (for example at peak times), your web browsing experience may be significantly affected. Furthermore, if your ISP’s DNS servers are located a considerable distance away from you, there may be significant DNS look-up delays.
There may be nothing wrong with your ISP DNS servers in terms of performance; it just may be that they are located much further away than a Public DNS server.
You can view the DNS server settings for the most popular ISPs by clicking on the following link:
According to Google, with the increasing complexity of web pages that reference resources (e.g. images) from numerous domains, DNS look-ups can become a “significant bottleneck” in the browsing experience.
Three ways to identify the best DNS servers
Since many broadband users use the router supplied by their ISP (using default settings), they will be using the ISP’s default DNS servers by default. Super mario 3d land rom download mediaf?re.
The good news is that you are generally able to choose whatever DNS servers you want and the best Public DNS servers may deliver improved DNS look-up performance compared to the DNS servers operated by your ISP. This is often a great performance tweak that will not cost you anything.
In increasing order of time and complexity, here are three ways to identify the best DNS server settings for your connection:
- just pick some from our ‘Top Three’ Public DNS services
- measure the ping to/from several DNS servers and pick the ones with the smallest ping
- download and run software (e.g. DNS Benchmark or Namebench) that thoroughly tests available DNS servers to identify the best for your location.
Let’s take each approach in turn.
Method 1: Just pick some DNS servers from our ‘Top Three’
Public DNS servers across the world have been extensively tested by different organisations and we have undertaken our own testing. We have found three Public DNS services consistently deliver excellent results: Google, Cloudflare and OpenDNS. You cannot go too far wrong by simply randomly picking one or more of these!
Here are some more options for Public DNS services:Provider | DNS servers |
---|---|
8.8.4.4 8.8.8.8 | |
Cloudflare | 1.1.1.1 1.0.0.1 |
OpenDNS | 208.67.222.222 208.67.220.222 |
Quad9 | 9.9.9.9 149.112.112.112 |
Level3 | 4.2.2.1 4.2.2.2 4.2.2.3 4.2.2.4 4.2.2.5 4.2.2.6 |
Sprintlink | 204.117.214.10 199.2.252.10 |
NTT | 129.250.35.250 129.250.35.251 |
Comodo Secure | 8.26.56.26 8.20.247.20 |
Verisign | 64.6.64.6 64.6.65.6 |

Method 2: Measure the ping and pick the smallest
Ideally, you want to use a DNS server that is geographically close to you because this will minimise the distance that the DNS look-ups will travel to the DNS server and the response travels back to your device.

We recommend that you measure the ping (e.g. using a computer or mobile phone application) for a broad range of Public DNS servers (for example, using our list above). Here are the results we got:
IP address of DNS server | Average ping (ms) | Minimum ping (ms) | Maximum ping (ms) |
---|---|---|---|
4.2.2.2 | 6.8 | 7.2 | 7.5 |
129.250.35.250 | 7.0 | 6.6 | 7.6 |
4.2.2.1 | 7.2 | 6.8 | 8.2 |
4.2.2.5 | 7.2 | 6.8 | 7.8 |
4.2.2.6 | 7.2 | 6.8 | 7.4 |
9.9.9.9 | 7.2 | 6.9 | 7.8 |
4.2.2.3 | 7.2 | 7.0 | 7.5 |
4.2.2.4 | 7.2 | 7.0 | 8.4 |
204.117.214.10 | 7.4 | 7.0 | 7.8 |
129.250.35.251 | 7.8 | 7.4 | 8.4 |
199.2.252.10 | 8.0 | 7.6 | 9.0 |
8.26.56.26 | 8.6 | 8.2 | 9.5 |
149.112.112.112 | 11.1 | 10.8 | 11.4 |
8.8.4.4 | 11.6 | 11.4 | 12.0 |
8.8.8.8 | 11.6 | 11.4 | 12.4 |
208.67.222.222 | 11.7 | 11.4 | 12.0 |
208.67.220.222 | 11.7 | 11.4 | 12.7 |
8.20.247.20 | 12.4 | 12.1 | 12.8 |
64.6.65.6 | 12.9 | 11.9 | 17.6 |
1.1.1.1 | 14.9 | 14.5 | 15.4 |
1.0.0.1 | 15.4 | 15.0 | 16.2 |
64.6.64.6 | 17.3 | 15.8 | 22.2 |

Namebench Mac
Bear in mind that you may get very different results. In our case, there was a substantial difference (about 10.5 ms) between the best and worst average ping time. We were also interested to find out that the ping to Google’s DNS servers (which are used by many broadband users to maximise performance) could be improved upon at our particular location. This shows the importance of determining the best DNS servers to use at your specific location as there is not one best setting for everyone.

Method 3: Identify the best DNS servers using DNS Benchmark or Namebench
If you are a perfectionist and want to test a large number of DNS servers, then two software programs can potentially help:
- DNS Benchmark (for Windows and Linux)
- Namebench (for Mac, Windows and Unix).
DNS Benchmark, which works with Windows (including Windows 10) can be downloaded from the following site:
After several minutes of processing, the DNS Benchmark program provides an ordered list of DNS servers.
Namebench runs on Mac OS-X, Windows and UNIX and can be downloaded from the link below:
Namebench has been the only option if you use a Mac. Sadly, the software has not been developed since 2010 and does not work with macOS Catalina.

As with DNS Benchmark, Namebench thoroughly tests the performance of your current DNS servers against a range of alternatives, to help identify the best DNS settings to use.
After its testing, the software will provide recommendations on DNS settings and will indicate the speed enhancement that you would obtain by changing your DNS settings to the recommended ones.
When Namebench is first run, it can take many minutes to gauge performance of all DNS servers tested. Please ensure that, while testing is being performed, your broadband connection is not being used, to ensure accurate results.
The screenshot below (click to view in full size) shows the output produced by the Namebench utility:
Namebench outputs a great deal of information. Don’t worry about messages such as “appears incorrect” or “is hijacked” as these are erroneous and point to the use of load balancing services sometimes used by large web providers.
The key metric to look at in the table is the average look-up time in ms (“Avg (ms)”). Minimum and maximum values are also provided to give an indication of the spread in look-up times. The DNS servers are listed in terms of performance, with the best performing DNS server at the top.
Namebench also provides several graphs, as shown below (click for full size), which are useful in comparing look-up times.
We recommend that you run DNS Benchmark or Namebench multiple times, and at different times of the day, in order to accurately gauge performance.
Dns Benchmark Mac Download Windows 10
If we’re being honest, after running DNS Benchmark and Namebench many times, well-regarded Public DNS services such as Google’s DNS service (8.8.4.4 and 8.8.8.8) generally perform very well. Once you are using excellent DNS servers, there’s a law of diminishing returns on extracting more performance.
Modify your router and device DNS settings
Once you have identified the best possible DNS servers, you will need to ensure that your devices are set up to use these DNS servers rather than the default ones.
The quickest way to change the DNS settings used by your devices is usually by changing DNS settings in your router, although annoyingly some routers (for example, the BT Home Hub) do not allow DNS server settings to be modified. As described below, it is still possible to change DNS settings in such cases on a device-by-device basis.
On your router, you will probably find the DNS settings in the settings associated with DHCP. As all routers are different, you may need to look at documentation for your particular router to understand how to change the DNS settings.
As an example, a screen shot for the Billion 8800AXL is shown below. For the Billion 8800AXL, the set-up menu can be found by selecting ‘Configuration’ and ‘LAN’. You simply enter the IP addresses of the top two DNS servers you have picked. Generally, we advise you to enter two DNS addresses. In the case that a DNS look-up fails with the first DNS server, a look-up using the second (backup) server on the list will be attempted.
While changing the DNS settings in the router is usually the most convenient way of propagating DNS settings across all your devices, you can manually change the DNS settings on each individual device (which can be more time consuming). This is usually very easy to do, although you may need to refer to your device instructions if you are unsure.
As an example with macOS, DNS settings can be found by going to ‘Open Network Preferences’ and then selecting your Internet connection followed by ‘Advanced’, and then the ‘DNS’ tab. The DNS addresses can then be entered.

We’ve previously discussed how to change the DNS servers on your Mac, iPad, and AirPort Extreme. But how do you know which DNS servers to use? There are dozens of free DNS providers, and all of them claim to offer the best service. Don’t worry. In this tutorial, we’ll show you how to find the best DNS servers, no matter where you’re located or which device you’re using.
Why Can’t Anyone Tell Me Which DNS Servers to Use?
Nobody knows which DNS servers are the best and fastest for you, because there are many different factors that can impact the speed of DNS service. Just like the quality of cellular network service, which varies widely from location to location, DNS service can also be influenced by your geographic location and Internet service provider. In short, there’s no one DNS server that is right for every individual.
Using Namebench to Find the Best DNS Servers
To find the fastest DNS servers for your Mac, iPad, or AirPort Extreme, try using Namebench. It’s an open source DNS benchmark utility that can quickly and accurately find the fastest DNS servers for your location. It does this by running a series of tests on your computer and comparing your current DNS servers to many other free DNS services. When the test is complete, the results will recommend the fastest DNS servers for you, personally.
Here’s how to use Namebench to find the best DNS servers:
Download Namebench, if you haven’t already.
Open the Namebench application. The window shown below appears.
Your Mac’s current DNS servers are displayed in the Nameservers field. Just leave these alone for the time being.
Select the Include global DNS providers checkbox to test all of the popular DNS services.
Select the Best available regional DNS services to test smaller, lesser-known DNS services that are available in your area.
Click Start to run the test. Be patient - the test could take a couple minutes to complete.
Once the test is complete, Namebench will open your web browser and display the test results, as shown below.
The recommended DNS servers for your Mac, iPad, and AirPort Extreme are shown in the Recommended configuration box. For best results, you should change your DNS to these servers.
In our example, OpenDNS was a whopping 54.5% faster than the DNS servers we were using. Hopefully you can realize similar gains!
Changing Your DNS Servers
Once you’ve used Namebench to find the fastest DNS servers, you should change the DNS servers on your devices. You can use the tutorials below:
Now sit back and enjoy the speed that comes with using the fastest DNS servers available to you!
