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.
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.
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.
To find and check the DNS server on your Mac, go to the Apple menu > Preferences > Network. Then, select the network that you want on the left. After that, click the “Advanced” button as well as the DNS tab. Remember to unlock the preference panel if there's a lock icon at the bottom.
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.
In this part, we are going to show you the easiest and quickest way for you to be able to clear out the DNS cache on your Mac. All you need to have is the FoneDog PowerMyMac and rest assured that you will be able to do this task as quick and easy as possible.

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.
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.
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
This method can be both applied on the El Capitan and Yosemite version of Mac. So here is how to do this.
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.
sudo discoveryutil mdnsflushcache
sudo discoveryutil ednsfushcaches
sudo discoveryutil mdnsflushcache;sudo discoveryutiludnsflushcaches;say flushed
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. This way, your problem will be resolved quickly.
