Hi Colin,

You see the entries below "# Auto-generated file.  Keep your
customizations at the bottom of this file."? You can remove them.

The general format is this:

Under ...
# Entries for localhost and primary IP address:

.. you will always have the 127.0.0.1. Additionally the public IP if one
of the Network interfaces has the "real" flag set to "1". That is
usually the case for eth0, eth1, eth2 (and so on) or venet0:0 in case of
a VPS.

If you only see 127.0.0.1 there, then apparently none of your CODB
Network entries has the "real" flag set to "1". As long as the primary
IP shows up somewhere else in another entry that should still be fine.
