Sorry xxx.xxx.xxx.175 is not a valid ip address!

[PPNSteve]

So we transferred an account from another cPanel server to our new one and have need to change the assigned IP .. we went to WHM's change a sites IP and selected the IP we wanted.. and promptly got this error message:
Sorry xxx.xxx.xxx.175 is not a valid ip address!

any ideas here? The IP is indeed assigned to the box, shows up in list IPs and pings.. In fact ALL of my IPs are failing with this error.

We need this resolved ASAP as this .180 IP is to used for another site (we've published it for users to use during our move/dns propagation)

This will be fixed in the next CURRENT build. It is working properly in all other branches.
