    For eth0 with dhcp:

    # The loopback network interface
auto lo eth0
iface lo inet loopback

# The primary network interface
iface eth0 inet dhcp

    For eth0 static:

    # The loopback network interface
auto lo eth0
iface lo inet loopback

# The primary network interface
iface eth0 inet static
    address 192.168.10.33
    netmask 255.255.255.0
    broadcast 192.168.10.255
    network 192.168.10.0
    gateway 192.168.10.254 
dns-nameservers 192.168.10.254

  2. Mine looks like:

    auto lo
iface lo inet loopback

  3. Following the Debian network configuration page, if you're just using DHCP then all you need is something like:

    auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

  4. Here are the default contents of /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
