Add name servers to the configuration file. On most Linux operating systems, the DNS servers that the system uses for name resolution are defined in the /etc/resolv.conf file. That file should contain at least one nameserver line. Each nameserver line defines a DNS server. The name servers are prioritized in the order the system finds them in
After making changes, you will need to turn off and reconnect the network to apply new settings. On Ubuntu 16.04 and older versions of Ubuntu, there was a file, /etc/resolv.conf, that was used to configure DNS name servers.

Domain Name Service (DNS) Domain Name Service (DNS) is an Internet service that maps IP addresses and fully qualified domain names (FQDN) to one another. In this way, DNS alleviates the need to remember IP addresses. Computers that run DNS are called name servers. Ubuntu ships with BIND (Berkley Internet Naming Daemon), the most common program Setting custom DNS servers on Linux can increase performance, security and even thwart some websites using Geo-blocking via DNS. There are several ways to do this including Network Manager GUI that's included in many Linux distros like Debian, Ubuntu and derivatives, Netplan which is now included as standard in Ubuntu 20.04; or using resolv.conf (not directly, but via the head file). The /etc/resolv.conf is the main configuration file for the DNS name resolver library. The resolver is a set of functions in the C library that provide access to the Internet Domain Name System (DNS).The functions are configured to check entries in the /etc/hosts file, or several DNS name servers, or to use the host's database of Network Information Service (NIS).
