Quite often, Internet users have difficulties accessing the network due to the fact that the Internet provider's DNS server is temporarily out of order. That is, the Internet channel is physically stable, but there is no access to resources due to the server's inoperability. A locally configured DNS server can help in these situations. The only problem is that most Microsoft user operating systems (Windows 2000 / XP / Vista) do not have a built-in DNS server, so you will have to use third-party developments.
It is necessary
- - a computer connected to the Internet;
- - unbound DNS server distribution.
Before you start installing your own DNS server, consult with the provider's support service to see if this process will interfere with the stable operation of your Internet connection, if it contradicts the general settings for a particular provider.
Download unbound-DNS from https://unbound.net/. The installer of this DNS server will be located in the Downloads section. You must select the installer that is designed for 32-bit Windows operating systems (even if you have a 64-bit operating system from Microsoft installed, most likely this application will run in compatibility mode).
Run the installer unbound (unbound _setup_X. XX, where X is the digital designation of the version you downloaded, on the developer's website, as a rule, you can find the most recent version at the moment), in the dialog mode follow the recommendations of the installer (where required, click "Next", where asked - read the license agreement and mark that you have read it). At the end of the installation, you just need to confirm its completion by clicking the “Finish” button. This completes the installation of the DNS server. You do not need to enable it - it starts automatically after the installation process is complete. After a reboot, it will automatically start too, unless you forcefully disable it.
Configure your network connection by specifying your local host as an additional DNS (the default Localhost IP address is 127.0.0.1) - this option is suitable if two DNS were specified in the network connection settings - primary and secondary. If the option "Obtain DNS server address automatically" was checked in the settings, then forcibly change the settings to manually enter the DNS server address and specify the localhost address (127.0.0.1) for both the primary and secondary DNS servers.
Check the availability of Internet sites - try to go to one of them. If the Internet is working, you can forget about this problem. If not, check the availability of your ISP's gateway, it is possible that the problem is with the physical connection to your ISP.
