Fix DNS Errors. A web page you’re trying to load won’t open when you’re working on your computer. You attempt repeatedly, but it is unsuccessful. What is happening?
There’s a strong probability that the issue you’re having is a DNS problem. You will learn how to identify and resolve DNS issues on Windows, Mac, and Linux in this tutorial. Additionally, we’ll demonstrate how to stop them from occurring in the first place.
Why Do DNS Errors Occur?
A DNS server issue, improper computer settings, or networking problems are just a few of the potential causes of DNS errors.
There are various techniques for finding and fixing DNS problems. Your DNS settings can be checked and adjusted on Windows using the command prompt. You can utilize the Network Utility on a Mac. Additionally, you can utilize a graphical user interface like GNOME NetworkManager or the command line on Linux.
Windows DNS error diagnosis
If websites are taking a very long time to load or won’t load at all, you might be dealing with DNS problems. We’ll go over some of the ways to see if you’re experiencing DNS issues below.
You might start by checking your computer’s DNS server settings. Open the Control Panel on Windows, then select Network and Internet > Network and Sharing Center to carry out this action. Then, select Properties by right-clicking on your active internet connection after clicking the link for Change Adapter Settings. From this point, you should scroll down to the Internet Protocol Version 4 (TCP/IPv4) section and select the Properties option. In the next window, you’ll want to enter the DNS server addresses provided by your ISP.
If the DNS server settings appear to be accurate, there may be a problem with your network architecture. You can ping the important domain nameservers to verify this and see if they are responding appropriately. You can accomplish this on Windows by using a Command Prompt window and entering “ping google.com” (without quotes). If you’re getting timeout errors or other odd replies, your network probably has a problem that has to be repaired.
Windows DNS Error Repair
The first thing you should do when encountering a DNS problem is verified your DNS configuration. By doing this on Windows, it is simple to accomplish the following:
Launch the Control Panel first.
Choose the Internet and Network.
Choose Network and Sharing Center in step three.
Choose Modify Adapter Settings.
Select Properties by right-clicking on your active network adapter.
Select Internet Protocol Version 4 (TCP/IPv4) and then click Properties in the Properties window.
Type the primary and secondary DNS server addresses provided by your ISP or domain name provider in the space for DNS server addresses.
If you’re still having problems after changing your DNS server addresses, there could be a problem with your network adapter or router. In this case, you should contact your ISP or router manufacturer for help in resolving the problem.
Identifying a Mac OS DNS Error
The procedure for identifying and resolving DNS issues is slightly different if you’re using a Mac. What you must do is as follows:
- Launch the Terminal program. This can be found in the Applications folder’s Utilities folder.
- Enter the command as follows: execute killall mDNSResponder: -HUP
- Hit Enter. By doing this, the DNS cache will be cleared, perhaps solving the issue.
- Restart your computer if that doesn’t work.
Fixing a Mac OS Dhcp Error
The procedure for examining and altering your DNS settings differs slightly on a Mac. However, it’s still fairly easy, so don’t worry.
You must first launch the System Preferences program. You can do this by selecting “System Preferences” from the Apple menu in the top-left corner of your screen.
Go to the System Preferences program and select “Network” from the menu.
Make sure your connection’s “Status” is set to “Connected” on the next screen. Click the “Disconnect” button and try connecting again if it isn’t.
When you are connected, select “Advanced” from the menu at the bottom of the screen.
Identifying and Resolving a Linux DNS Error
There are a couple of different techniques to check for DNS problems if you use Linux. The dig command is one approach. Enter “dig +short myip.opendns.com @resolver1.opendns.com” once you have finished typing.
Your DNS is operating correctly if you can see your IP address. However, if you encounter an error message, something is wrong.
You can try switching your DNS server to see if that fixes a DNS issue on Linux. This can be done by making changes to the /etc/resolve.conf file. Simply open it in a text editor and enter the IP address of the DNS server you want to employ. By including the following, you can utilize Google’s public DNS server as well as lines:
