Dns Benchmark For Mac

By Adela D. Louie, Last updated: December 18, 2019

Ever wonder what DNS servers on your Mac are? Would you want to know on when or how are this DNS servers work? Well, in this article, we are going to know more about the DNS server on your Mac and on how you can find them. So if you are one of those people who are actually curious about it, then this is for you.

Part 1: What is A DNS Server?

  1. This article will explain what DNS cache is, why your computer saves it, and how to flush DNS cache on Mac. What Is the DNS Cache? DNS servers convert domain names, like www.abc.com, into numerical web addresses that computer systems can process. By default, browsers contact the DNS servers whenever a web address is being accessed.
  2. This portable Windows application includes all the common network utilities for diagnosis.
  3. DNS Speed Benchmark Test the performance of your DNS provider from all over the world using this benchmark tool. Free test limit reached. This tool is limited to 6 benchmarks. You can contact us at [email protected] If you need to run more tests as soon as possible.

If a certain device such as your Mac does not have a DNS server, then you will not be able to access the internet on your device. This is because a DNS server is one of the most crucial parts of the DNS infrastructure. DNS stands for Domain Name System.

If you are using Windows for any part of the time, you might be familiar or even used.

Pro

This is where you will be able to find the IP addresses and as well as the hostnames and the data that is used for you to fix any problems that the user might encounter on a certain website, a device or some other network system that is using an IP address. Truly, DNS is very handy.

Part 2: When Do We Use DNS Servers?

Once that a user types in a certain host or website or a URL on the address bar on one of their browsers, the DNS resolver will then immediately contact the DNS server for it to be able to find the IP address that is somewhat connected to the website that you are trying to access. And, once that the DNS server is not able to locate any information that it needs, then it will move along to the DNS server in the DNS hierarchy until such time that it was able to locate the data that it needs.

Part 3: How to Find DNS Server on Mac

Now, for you to be able to check on the DNS server that you have on your Mac, here are the steps that you should follow.

  1. Go ahead and launch System Preferences. You can see this from the Dock of your Mac or you can also go to the Apple menu and then choose “System Preferences”.
  2. And then, once that the System Preferences appears on your screen, go ahead and choose the “Network” icon. Then the network configuration will be shown on your screen. This will show you the status of the active ports.
  3. Then, in the left-hand area, go ahead and select the network that you would want to see.
  4. After that, go ahead and click on the “Advanced” button and as well as the DNS tab.

NOTE: If you were able to enter the setting manually, then the MIT DNS servers will be listed on your screen in black font. If you have this, you can go ahead and click on the minus (-) sign for you to remove it. However, once that the DNS server appears grey on your screen, then that means that they were assigned automatically. And once that you have left the MIT campus, then the DNS settings will be updated on your local network provider.

That is how easy to find the DNS server on your Mac if you are wondering about where you can check on it.

Part 5: Cleaning DNS Cache Manually on Mac

Before we go ahead and proceed with the cleaning of your DNS cache on your Mac, we have to warn you that doing this will interrupt any active web. That is why it is better for you to close any browsers first before doing this.

The methods that we are going to show you will depend on what type of Mac you are using. So, just go through the methods and look for the one that has the type of the Mac you are using.

Method #1: Flushing DNS Cache on macOS High Sierra

  1. Go ahead and launch Finder on your Mac.
  2. And then, choose Applications, then click on Utilities and then Terminal.
  3. After that, go ahead and enter these commands: sudo killall -HUP mDNSRespoder; sleep 2; echo macOS DNS Cache Reset say
  4. After entering the command, go ahead and press on the Return button and then enter your password. And once again, press the Return button.
  5. Then, you will be able to see a message on your screen that says “macOS DNS cache reset”.
  6. Then once you are done, go ahead and exit Terminal.

Method #2: Flushing DNS Cache on macOS Sierra

This method is actually a little similar on flushing DNS on a High Sierra Mac. However, only the syntax for this one is different. Here is what you need to do.

Benchmark
  1. Go ahead and launch the Finder on your Mac.
  2. And then, go ahead and choose Applications and then choose Utilities and then choose Terminal.
  3. After that, go ahead and this command: sudo killall -HUP mDNSResponder;say DNS cache has been flushed
  4. After entering the command, go ahead and press the Return button and then key in your password. Once done with the password, press the Enter command again.
  5. And then lastly, listen to the audio alert. Once that you hear that alert, then that means that the DNS cache was successfully removed from your Mac.

NOTE: If the command that we have provided above does not work for you, then you can go ahead and use this alternative syntax.

sudo killall -HUP mDNSResponder;sudo killall mDNSResponderHelper;sudo dscacheutil -flushedcache;say Mac DNS cache has been cleared

Method #3: Flushing DNS Cache on Mac OS El Capitan and Yosemite

This method can be both applied on the El Capitan and Yosemite version of Mac. So here is how to do this.

  1. Go ahead and launch Finder on your Mac.
  2. After that, go ahead and click on the Applications and then choose Utilities and then click Terminal.
  3. Once that you are in Terminal, go ahead and enter the following command:
  4. sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder;say cache flushed
  5. And then, go ahead and press on the Return button and then key in your password. Once done, press on the Return button again.
  6. After that, wait for the alert tone which means that the process is successful.
  7. Then once that you are done, go ahead and exit Terminal.

TIP: If you are using the OS X Yosemite version 10.10, 10.1, 10.10.2 and the 10.10.3, then the process of these are a bit different. For you to be able to completely flush your DNS cache, you have to clear out the Multicast DNS and as well as the Unicast DNS.

  • For you to clear the MDNS cache, all you have to do is to enter these command in the Terminal:

sudo discoveryutil mdnsflushcache

  • And then, for you to be able to clear the UDNS cache, just do the same process above but enter this syntax on Terminal:

sudo discoveryutil ednsfushcaches

  • And then, for you to be able to clear both the MDNS and UDNS cache at once, go ahead and do the same steps but enter these command line:

sudo discoveryutil mdnsflushcache;sudo discoveryutiludnsflushcaches;say flushed

Part 6: Conclusion

Now, you already know how you can find the DNS server on your Mac both manually and the easiest way. Now, if you are actually facing some problems about the websites that you are trying to visit, then it is a great idea that you clear out your DNS cache on your Mac.

Whenever you try to access a website, a DNS server is the one that is responsible for resolving the IP address of the website address you just typed. Typically, your ISP (Internet Service Provider) provides with a default DNS server so that you can access the internet properly. However, the default DNS server provided by the ISP may not be that fast, secure, or reliable. Especially, they won’t have a huge infrastructure like Google Public DNS or OpenDNS which arguably provide faster and better DNS services.

Fortunately, there are a ton of third-party DNS services to choose from. However, you can’t just randomly choose one and hope it is faster than the one provided by your ISP. To deal with that, here are some of the best DNS benchmarking tools that can reliably test the speed and security of a wide range of DNS servers so that you don’t have to do the guesswork.

Best DNS Benchmarking Tools

1. DNS Jumper

If you are using Windows for any part of the time, you might be familiar or even used some free and small software from Sysinternals or Nirsoft utilities. One such other developer who creates small, lightweight and free software is Sordum.

Off all the software from Sordum, DNS Jumper is the one that I’m using for years. Personally, it is one of the best when it comes to finding and setting fastest DNS on your system. The good thing about DNS Jumper is that it is not only lightweight but is also portable. Moreover, the software packs a lot of features within its small file size. For instance, DNS Jumper has a pre-configured list of 27 different DNS services. If you cannot find the DNS service you are looking for, you can add it with the name of your choice with just a few clicks.

Of course, you can benchmark all the DNS services in the list with a single click. To benchmark the available DNS services, just click on the “Fastest DNS” button appearing at the left-hand side of the window.

When the software finds the fastest DNS, it highlights that specific DNS in the list. You can set it as your DNS by clicking on the “Apply DNS Server.” If need be, you can mix and match DNS addresses for more reliability and speed. Just select the checkbox “Mixed” before starting the DNS benchmark test.

To set a custom DNS server, simply select the checkbox “Custom DNS Server,” enter the DNS addresses in the available fields and click on the “Apply DNS” button appearing on the left side of the window. If you want to, you can benchmark the DNS response time by clicking on the “Check Resolve Time” button under address fields.

Like I said, for ease of access, you can add your own custom DNS servers to the list. To do that, click on the “Gear” icon appearing in the Choose a DNS Server field. Now, Enter DNS Server Name, first and second DNS addresses and click on the “Add” button and you are good to go. When you benchmark next time, your custom DNS server is also tested.

If you want to, you can create DNS groups and divide the available DNS servers into different folders like family safe, secure, unblock, etc. To create a DNS Group, click on the “+” icon next to the “Default DNS List,” type a name and press “Enter.”

So, if you are looking for a fully featured DNS benchmark tool which does more the benchmarking different DNS servers then DNS Jumper is for you. Being a free software, give it a try and see if it fits your needs.

2. DNS Benchmark

If you are looking to benchmark various DNS servers with comprehensive reports then you should try DNS Benchmark from GRC. The software may look simple at first glance but it is pretty good at what it does.

The best thing about this software is that unlike other software which just shows the response time, DNS Benchmark gives you some extensive data like minimum response time, average response time, maximum response time, the standard deviation of each DNS Server, and their reliability.

To benchmark, all the available DNS servers, simply go to the “Nameservers” tab and click on the “Run Benchmark” button. When benchmarking each DNS server, the software does three different tests like Cached Name, Uncached Name, and DotCom Lookup for accurate results. While at it, DNS Benchmark also does the DNSSEC Authentication test on every DNS server. Due to all these tests, it can take some time to complete the benchmark.

Once the test has been completed, DNS Benchmark will sort the servers by fastest first. If you go to the “Tabular” tab, you can find the detailed test results.

Dns Benchmark For Mac

Just like DNS Jumper, DNS Benchmark has 20+ pre-configured DNS Servers to benchmark. If you can’t find your favorite DNS server, simply click on the “Add/Remove” button to add the DNS server.

Unfortunately, DNS Benchmark doesn’t offer any way to set the DNS server directly. You have to manually set it on your OS or router. All in all, DNS Benchmark is a pretty good software to have in your repository. After all, it is free, lightweight, and portable. So, give it a try.

3. Namebench

Dns Benchmark Pour Mac

Namebench is one of the simplest and oldest software to benchmark DNS servers. Of course, just like the other software on this list, Namebench is also free, lightweight and portable. Though the developer has not released any new update for quite a long time, it still works like a charm. There is also a MacOS version. The DNS servers it tests include but not limited to Google Public DNS, OpenDNS, UltraDNS, RoadRunner, Comodo Secure DNS, DynGuide DNS, etc.

The cool thing about Namebench is that it can even do censorship checks on all the DNS servers in the list. Moreover, depending on where you live, it can also add best available regional DNS services which often provide better speed by virtue of being near to you. Other than that, you can also customize other settings like your location, health check, number of quires, and query data source.

If you can’t find your favorite DNS server within the list, simply enter those DNS IP addresses in the Nameservers field and then click on the “Start Benchmark” button. Unfortunately, there is no way you can add your own DNS server addresses to the list. You have to manually enter them each and every time you want to benchmark the DNS servers.

That being said, the other thing I really like and that is sorely missing from the other two software I shared earlier is that it can detect when your ISP is disregarding your custom settings and redirecting all the DNS traffic via their own servers. When an ISP is redirecting all your DNS traffic, no matter what DNS server you set in your OS or Router, the DNS quires will still go through the ISPs DNS server.

Simply put, you won’t get the benefits of speed, security, and parental control provided by the third-party DNS servers. If your ISP is doing such a thing, all you can do is ask or petition them to respect your changes or move to another ISP who respects your configurations.
