Not really.
The easiest way is have your rDNS/PTR set already at your host.
Change the IP for CWP in the support section.
The log into your server, and manually change the base IP, if you only have 1 IP you are changing.
Reboot the server, CWP will see the change.
You then can goto CWP Settings -> Edit Settings, and confirm your new IP is listed as the Shared IP.
It will pull that IP the same as the Base IP.
Click Save Changes, and the IP should propagate to all accounts.
Changing an IP isn't easy.
