ifup is one of the utilities that can be used to configure the network interfaces. It reads its configuration from /etc/network/interfaces:
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). source /etc/network/interfaces.d/* # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto ens5 iface ens5 inet static address 192.168.1.10 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 184.108.40.206 220.127.116.11 18.104.22.168
DNS resolver is configured with resolvconf, which writes /etc/resolv.conf. Normally, resolvconf is invoked by network interface configuration programs, such as ifup, NetworkManager or dhclient. resolvconf can be run by administrators, but this s normally necessary. /etc/network/interfaces contains DNS-related configuration keywords: "dns-nameserver", "dns-search", "dns-nameservers".
