RE: [cobalt-users] RAQ1 urgent question: renumbering IPs

["ISP" <isplists@xxxxxxxxxxxx>]

You're welcome. Had to do this twice in one month recently. I wish I could
find a script that could do it but I'm no Perl whiz. It's tedious but if you
make use of your shell history (arrow keys on keyboard)& backspace you can
do it fairly quickly. I believe your Broadcast IP should be 216.218.208.254
but check
with your upstream provider..they should have supplied that info
to you along with your netmask which should be 255.255.255.128 if you have
126 usable IP's.

Thank you for those helpful details... That's kind of what I suspected, got
to edit all the files in /etc/sysconfig/network-scripts individually.

One last question in:

DEVICE=eth0:2
IPADDR=165.90.27.133
NETMASK=255.255.255.192
NETWORK=165.90.27.128
BROADCAST=165.90.27.191
ONBOOT=yes
ALIAS=yes
BOOTPROTO=none

what is the BROADCAST IP? My new allocation is 216.218.208.128/25 (if that
can be of help)

Again thank you very much.

Regards,

David
