    User IP addres is not valid

    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.

    http://www.doc.ic.ac.uk/~ih/doc/pc_conn/tcpip/intro/intro7.html

    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.
    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.

    It's reporting it because that is what the server is reporting. vB does not independently make up IP addresses.

      By "server" do you mean the server operating system, Linux?

      So this is something I need to talk to my hosting company about?

        The server that your vB is running on.

            is a valid IP, it is not a broadcast IP. A broadcast IP ENDS in .255, this is not the same.

            Also, your IP address can have 0 in it, but the IP cannot begin or end with 0.

            Consider:

            192.168.0.1 (A very popular private network IP address)
            10.0.0.1 (another popular private network IP address)

            10.0.255.1 is valid, also. It's when you have:

            10.0.0.255 that it is invalid.
