Origin DNS error |
Have you encountered a strange browser error when trying to access a website? These are usually DNS errors. You can still use services like Skype and play online games, but websites won't load. It happens that this error pops up selectively, only on some sites. So what is this “DNS error”, why does it prevent certain or all sites from opening, and how can it be fixed?
DNS stands for Domain Name System and is usually associated with a "DNS server". To understand how a site loads in general, it is worth understanding what the role of DNS is in this process.
The DNS server is like a phone's address book. Of course, you can manually dial the desired number each time, but it's much easier to memorize all the numbers and give each one a name - "Vova", for example, so that when you want to call Vova, you can simply find his name in the list and press call.
The same is true for your computer. He doesn't know what "Google", "Facebook" or "Twitter" is. But he knows wh Origin DNS error | at an IP address is. When you type in a website address - say www.facebook.com - the computer understands that it's a URL and goes into the "address book" of URLs to find out where Facebook is located on the web. That's what a DNS server does - it's like an address book for URLs.
What happens if the address book on your phone gets corrupted or deleted? You enter "Vova", but the phone cannot find his number and call him. Similarly, if you enter a URL in a browser and the DNS server is not available, your computer cannot get the IP address of the desired site. And instead of loading the site, you get a DNS error message.

Interesting to read: How to find out the IP address, read here!
The smartest readers have already guessed that if you enter the IP address of the desired site directly into the address bar, the site will open, and so you can technically surf the network even if the DNS server is not available. And although it is possible, you don't really want to remember all the IP addresses in case the next "fall" of the DNS server. Where better to deal with the problem.
You now know enough about what DNS is. Let's see what can be done in case of problems with DNS.
If you frequently visit the same pages, it is more convenient for the computer to remember their addresses so that it does not need to contact the DNS server each time. This address store is called the DNS cache. It happens that if this cache is corrupted, the computer, turning to it for an address, gives an error.
Clearing the DNS cache in Windows is very easy. Press the Win key and type cmd. How to clear the cache in Mofilla FireFox or on an Android phone, I already wrote. When the command prompt appears in the search results, right-click on it and select "Run as administrator". A command prompt window will open where you can make changes at the system level.
To clear the DNS cache, enter the command:
The commands for flushing the DNS cache on Apple operating systems seem to depend on the direction of the wind. There are at least four different commands for every single version of OS X. So here we present only the most "new".
To clear the DNS cache in MacOS X, you need to launch a terminal command window. Go to Applications, find an app called "Terminal" and launch it. Next, enter the following command.
