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

[PowerClicks <david@xxxxxxxxxxxxxxx>]

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
