IP address troubles

Every couple days, my cPanel server will stop being communicating on one of its IPs. If I look in WHM, the IP isn't listed, but if I try adding it, it says it's already been added. Running /etc/rc.d/init.d/ipaliases restart
from the console fixes the issue. What am I actually doing when I run that command? I'd like to figure out what's actually causing the problem so I don't need to keep fixing it. Is it something that's possibly the server host's fault, or more likely a misconfiguration on my end?

  Check the IPs are up with: ifconfig

  I'm not having the issue at the moment, but as I recall the problem IP does not show up in ifconfig. All the functioning addresses do. I'll double-check next time it happens and update this post.

  It looks like a misconfigured firewall was blocking access to the data center's DHCP server. My guess is that's what was causing issues.

  You may also want to review the files in /etc/sysconfig/network-scripts to verify the proper entries are added for the IP address in question. Thank you.

  Make sure that you are adding valid IP range via whm with correct subnet. This may also cause the problem.
