We have no idea HOW you are adding a new address, you've told us nothing useful about this. However, you must be doing something wrong though, as there should never ever be a need to reboot for something like that. Update the entry in the ifcfg-eth0 file and and a "ifdown eth0; ifup eth0" should have it all put into place.

I forget what it is called but most distro's say after you change settings like that you need to restart network manager or services. A reboot would do that but pretty sure it can be done from command line. A RH person ought to know exact command to do that.

sudo service network restart

no need for sudo, in fact subo is not configured by default in CentOS. this needs to be done as root.


# service network restart
will do the trick.
