VBulletin version: 3.7.2 pl1
On my forum, a certain members profile, VBulletin is reporting their IP address as 63.167.255.152 - This is not a valid IP address,
63.167.255 <---- the .255 is the broadcast address. Valid IP addresses are from 1 - 254, 0 is the network range and 255 is the broadcast.

Why is VBulletin reporting the IP address this way? This is a problem member that I want to ban on the server level, but Cpanel is rejecting the IP address because it is not a valid address.

0 and 255 have special meanings. 0 is reserved for machines that don't know their address. In certain circumstances it is possible for a machine not to know the number of the network it is on, or even its own host address. For example, 0.0.0.23 would be a machine that knew it was host number 23, but didn't know on what network.
255 is used for "broadcast". A broadcast is a message that you want every system on the network to see. Broadcasts are used in some situations where you don't know who to talk to.
