Dns lookup failed error: causes and consequences

The “dns lookup failed” error occurs when a computer cannot perform a DNS lookup of a DNS name to an IP address. DNS (Domain Name System) is a service that translates domain names into corresponding IP addresses. If a “dns lookup failed” error occurs while performing a DNS query, it may be due to several reasons.

Causes of dns lookup failed error:

Internet connection problems: If you have no or limited access to the Internet, your computer will not be able to contact the DNS server to perform the query. In this case, check your Internet connection.
** Incorrect DNS settings:** If your computer or router has incorrectly configured DNS servers, a “dns lookup failed” error may occur. Make sure that the DNS settings are specified correctly.
DNS Server Problems: If the DNS server is unavailable or malfunctioning, the computer will not be able to perform a DNS query. In this case, try checking the DNS server status or use alternative DNS servers.

Consequences of dns lookup failed error:

If a “dns lookup failed” error occurs, it may affect your ability to open web pages, send and receive emails, and utilize other network services that depend on the proper functioning of DNS. You may experience the following problems:

Inability to access certain Web sites
Long loading times for web pages
Problems sending and receiving e-mail

The “dns lookup failed” error can be fixed by following some simple solutions that will help you restore the normal functioning of DNS queries and eliminate problems with accessing network resources.

No Internet connection

When the DNS Lookup Failed error occurs, there may be a problem with your internet connection. Check the following items to make sure you have a connection:

Make sure you are connected to Wi-Fi or using a network cable.
Reboot your router or modem.
Check other devices connected to the same network. If they are also experiencing problems connecting to the Internet, the problem may be related to your service provider.
If you are able, check the connection via mobile data to rule out possible problems with the dedicated network.

If the internet connection problem persists, contact your internet service provider for further assistance and to diagnose the problem.

DNS server problems

The DNS server is one of the key components of the Internet, responsible for translating domain names into corresponding IP addresses. However, sometimes there can be problems with its operation, which can result in a “DNS lookup failed” error. Let’s take a look at a few common problems and how to solve them.

1. Unavailable DNS server

One of the most common causes of the “DNS lookup failed” error has to do with the unavailability of the DNS server your computer is trying to access. This can happen for several reasons:

Network connectivity problems;
DNS server is temporarily unavailable or out of service;
Incorrectly configured network settings.

To fix this problem, you can:

Check the network connection and make sure it is working properly;
Restart your router and modem;
Change your DNS servers to a more reliable and public DNS server, such as Google Public DNS or Cloudflare DNS;
Update or reconfigure the network settings on your computer.

2. DNS settings are not correct

Sometimes, the cause of “DNS lookup failed” error may be due to incorrect DNS settings on your computer or in your router. In this case you can:

Check that the DNS servers specified on your computer or in your router are correct;
If you are using automatic network setup, try manually specifying DNS servers;
Restart your computer and router after making changes to the DNS settings.

3. DNS caching problems

Another reason that causes the “DNS lookup failed” error may be due to DNS caching problems. DNS cache stores data about previous DNS queries to speed up access to websites. Sometimes, the cache may contain outdated or incorrect entries, resulting in errors. To fix this problem, you can:

Clear the DNS cache on your computer;
Reboot your computer and router after clearing the DNS cache.

If the DNS server problems do not disappear after performing the above steps, it may be due to other technical problems or configuration errors. In such a case, it is recommended to seek help from specialists or your ISP.

Incorrect configuration of DNS settings

The problem with DNS lookup failed may be caused by incorrect configuration of DNS settings on your device or router. DNS servers are responsible for translating domain names into corresponding IP addresses. If the DNS settings are incorrect or missing, the device will not be able to find the correct IP address for the domain and an error will occur.

Here are some steps you can take to correct the problem with misconfigured DNS settings:

Check the DNS settings on your device: Open the network settings on your device and make sure the DNS servers are specified correctly. You can use public DNS servers such as 8.8.8.8.8 (Google Public DNS) or 1.1.1.1.1 (Cloudflare DNS).
Reboot your router: Sometimes the problem can be caused by misconfigured DNS settings on your router. Try rebooting your router and see if the problem is fixed.
Change DNS settings: If the problem persists after checking the settings and rebooting the router, try changing the DNS settings on your device or router. You can manually specify DNS servers or use automatic configuration via DHCP.

If the DNS lookup failed problem continues to occur after following these steps, it is recommended that you contact your internet service provider or system administrator for further assistance and to verify your network configuration.

3 ways to fix dns lookup failed

The “dns lookup failed” error may occur when trying to open a web page and indicates a problem accessing the DNS server. In such a situation, you can try the following solutions:

Check your DNS settings First of all, you should make sure that your DNS server settings are correct. To do this, you can use the command “ipconfig” in the command line (for Windows users) or the command “ifconfig” (for Linux/Mac users). In the output of the command you need to find the “DNS server” section and make sure that the correct DNS server address is specified. If the address is incorrect, you can correct it in the network adapter settings.
Reboot the router and computer Sometimes rebooting your router and computer can help fix the dns lookup failed error. Just unplug them for a few minutes, then plug them back in.
Use an alternate DNS server If the problem still persists, you can try using an alternate DNS server. To do this, you can change your network adapter settings and add an alternative DNS server address, such as Google Public DNS addresses (8.8.8.8.8 and 8.8.8.4.4) or OpenDNS (208.67.222.222 and 208.67.220.220).

If none of these solutions help, the problem may not lie in the DNS server settings, but in other aspects of your network connection or computer. In this case, it is recommended to contact a specialist or ISP for further diagnosis and correction of the problem.

Rebooting your router and computer

One of the first and easiest ways to fix the “DNS lookup failed” error is to reboot your router and computer. This can help fix temporary problems with your network or network settings.

To perform a router and computer reboot, follow these instructions:

Reboot the router by pressing the power button or unplugging it from the power source.
Wait a few seconds and turn the router back on.
Reboot your computer by pressing the power button or selecting the Reboot option from the Start menu.

After rebooting, check to see if the “DNS lookup failed” error is corrected. If the problem persists, move on to the next fix method.
