ifup
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

DNS Resolver
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".
