What Is DNS Failure? Common Causes And Solutions

Everyone has had the unpleasant experience of working on a web project when suddenly a “DNS server not responding” error appears and everything stops.

Errors like these are not uncommon, but they can be annoying and slow down your work. Fortunately, there are several ways to quickly resolve DNS errors so that you can continue working without interruption.

Why do DNS errors occur?

DNS errors are primarily caused by an inability to connect to an IP address, which can mean that network or Internet access is lost. This is a network of servers that keeps track of the alphanumeric names of all devices connected to the Internet and all websites around the world, along with their corresponding numeric IP addresses.

In other words, DNS translates Internet domain names into IP addresses and vice versa. If you type “www.google.com” into your browser, the server doesn’t understand what it means and doesn’t know where to point you.

Common DNS problems: TCP/IP

One of the most common causes of DNS errors is TCP/IP software, or Dynamic Host Configuration Protocol (DHCP), which assigns IP addresses to devices and manages the addresses of DNS servers. The easiest way to resolve these issues is to simply reboot the computer, but TCP/IP tools can also be used to correct the configuration. Finally, it is recommended to ensure that DHCP is enabled on both the router and the device being used.

DDOS attacks

This requires the best security features; DNS issues can be the result of malicious hacking attacks. This is done by sending large amounts of traffic to a website and crashing it. This is why you should invest in other security features.

The Solution

Problems with the Embassy This is also more of an ISP problem. Some ISPs (such as AOL) allow all users to browse through a proxy server. Proxy servers sit between you and the real Internet and are used to cache infrequently changing content and, in some cases, to block access to certain websites and Internet services. In most cases, shortcuts work without your knowledge, but sometimes they can cause confusion and problems.

Update the network adapter drivers and reinstall them if necessary

It’s been a while since you updated your drivers. Problems may occur, especially if new hardware has been added since purchase; DNS issues can be resolved by checking and manually updating the network adapter drivers.
