IPv4 loopback

[Keith E. Brandt, M.D.]

While trying to configure ntp, I discovered that my IPv4 loopback was 
not being configured. I can manually restart it with 'ifconfig lo0 
add 127.0.0.1', however, it does not survive a reboot.

Here's the output of ipconfig following boot:

rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
         options=8<VLAN_MTU>
         inet 192.168.0.100 netmask 0xffffff00 broadcast 192.168.0.255
         ether 00:08:54:dd:65:8d
         media: Ethernet autoselect (100baseTX <full-duplex>)
         status: active
plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST,NEEDSGIANT> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
         inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
         inet6 ::1 prefixlen 128

and after manually configuring:

rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
         options=8<VLAN_MTU>
         inet 192.168.0.100 netmask 0xffffff00 broadcast 192.168.0.255
         ether 00:08:54:dd:65:8d
         media: Ethernet autoselect (100baseTX <full-duplex>)
         status: active
plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST,NEEDSGIANT> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
         inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
         inet6 ::1 prefixlen 128
         inet 127.0.0.1 netmask 0xff000000


What do I need to configure to get it to come up at bootup? Any 
thoughts as to why it disappears?

Goodbye cruel world that was my home-
   there's cleaner space out here to roam
Put my feet up on the moons of Mars-
   sit back, relax, and count the stars
