i cannot find 127.0.0.1 in loopback.

$ ping 127.0.0.1 ping 127.0.0.1 (127.0.0.1) 56(84) bytes of data.
it's no response long time.
$ cat /etc/network/interfaces # file describes network interfaces available on # system , how activate them. more information, see # interfaces(5). # loopback network interface auto lo iface lo inet loopback # primary network interface auto eth0 iface eth0 inet static address 128.199.xxx.xxx netmask 255.255.xxx.0 gateway 128.199.xxx.1 dns-nameservers 8.8.4.4 8.8.8.8 209.244.0.3
/etc/network/interfaces. it's default.
