Here's a section from my /etc/network/interfaces file:

#
# Loopback interfaces.
#
# We define the standard lo loopback interface as well as two aliases
# on it (lo:1 and lo:2). These interfaces are used to run private DNS
# servers (lo:1 for private root DNS servers and lo:2 for private non-
# root DNS servers). This use of private DNS server IP addresses is
# documented at http://cr.yp.to/djbdns/faq/cachex.html .

auto lo lo:1 lo:2

iface lo inet loopback

iface lo:1 inet static
  address 127.53.0.1
  network 127.53.0.0
  netmask 255.0.0.0

iface lo:2 inet static
  address 127.53.0.2
  network 127.53.0.0
  netmask 255.0.0.0
