it is not there but it does show up in ifcfg-eth0:0

DEVICE=eth0:0
IPADDR=OOO.OOO.OOO.OOO
NETMASK=255.255.255.0
NETWORK=OOO.OOO.OOO.AAA
BROADCAST=OOO.OOO.OOO.BBB
ONBOOT=yes
ALIAS=yes
BOOTPROTO=none

"ifcfg-eth0:0" 8 lines, 139 characters

Now my question is this, the file  it resides in is, I expect, not needed.
the contents of the directory are here listed:

root@bluefish:/etc/sysconfig/network-scripts$ dir
ifcfg-eth0         ifdhcpc-done       ifup               ifup-sl
ifcfg-eth0.master  ifdown             ifup-plip          network-functions
ifcfg-eth0:0       ifdown-post        ifup-post
ifcfg-eth0:1       ifdown-ppp         ifup-ppp
ifcfg-lo           ifdown-sl          ifup-routes
root@bluefish:/etc/sysconfig/network-scripts$

Which of these should remain, and which should be removed.

Right now I am not too concerned with the name issue, I know it will take
time to clear the name from the name servers.  MY concern was moving this
box to a new ip due to hacking concerns.  I just want to be sure it does not
respond to more than one ip.
