环回网络接口没有 IP 地址

我不明白为什么我的环回设备没有 IP 地址。

这是 /etc/network/interfaces：

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
address 10.33.11.204
netmask 255.255.0.0
gateway 10.33.1.1
network 10.33.0.0
broadcast 10.33.255.255
dns-nameservers 10.33.3.21 10.33.3.150

下面是ifconfig -a：

eth0      Link encap:Ethernet  HWaddr 00:50:56:99:57:43  
          inet addr:10.33.11.204  Bcast:10.33.255.255  Mask:255.255.0.0
          inet6 addr: fe80::250:56ff:fe99:5743/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:7294 errors:0 dropped:0 overruns:0 frame:0
          TX packets:597 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:585520 (585.5 KB)  TX bytes:86074 (86.0 KB)

lo        Link encap:Local Loopback  
          LOOPBACK  MTU:65536  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

下面是ip addr show：

1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:50:56:99:57:43 brd ff:ff:ff:ff:ff:ff
    inet 10.33.11.204/16 brd 10.33.255.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::250:56ff:fe99:5743/64 scope link 
       valid_lft forever preferred_lft forever

到底发生了什么事？我有另外两台具有类似网络配置的服务器，并且均将 127.0.0.1 作为环回 IP 地址。
