What's the default /etc/network/interfaces?

I messed up my network configuration. Can anyone help me and copy the default /etc/network/interfaces?

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

Mine looks like:

auto lo
iface lo inet loopback

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

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
