How to configure DNS resolver.
To configure DNS resolver, you can follow these general steps:
Determine the DNS resolver configuration file location. The location of the configuration file can vary depending on the operating system you are using.
Open the DNS resolver configuration file with a text editor. For example, on Linux systems, the DNS resolver configuration file is typically located at /etc/resolv.conf.
Edit the configuration file to add the IP addresses of the DNS servers you want to use. You can add multiple DNS servers by listing them one after the other, each on a separate line. For example:
nameserver 8.8.8.8
nameserver 8.8.4.4
Save the configuration file and exit the text editor.
Test the DNS resolver configuration by running a DNS lookup command, such as nslookup or host, and verifying that the results are correct.
Note that some operating systems may use different methods for configuring the DNS resolver, such as network settings or system preferences. It is recommended to consult the documentation for your particular operating system for more detailed instructions on configuring the DNS resolver.
