    I just hade a IP conflict where 2 of my servers did not respond at all.
    Suddenly it worked again and my NOC say it might be someone else using
    the IP adressess so it's a conflict. They should look into it soon.

    But - is it so easy to "steal" IP adesses from the same NOC ??
    They said they could bind the IP's to the mac address or something but they did not
    wanted to do that.

    Anyone have any info, experience or feedback about this ?

    When I add IP's that has not been given to me, in cpanel they turn up green
    and working. I deleted them again quick offcoruse, just wanted to test..

    Steal is a strong word. I had clients do the same. They try to add new addresses to their IP pool without requesting them from the datacenter. Ends up they get assigned an address already provisioned to another server.

    After looking into why an additional nameserver ip would not work, I found that it was indeed provisioned elsewhere. Although it can be done maliciously, most of the time I would think its an innocent mistake.

    It's harder across the net to impact a server that way but if you
    have any 2 servers behind the same router that attempt to
    use the same IP address, they will effectively jam each other
    and take each other off the network.

    This is actually a common (but stupid) problem and
    usually occurs for 1 of 2 reasons:

    1. Setting up an IP without getting authorization first.
    (Some people assume they can add IPs in the same
    subnet arbitrarily to their servers even though those
    IP numbers haven't been assigned to them)

    2. Simple typographical error.

    It is actually very rare (though possible) that someone
    using your server's IP really meant to be malicious or
    otherwise a deliberate attack on you.

    Stealing? Really wouldn't use that word here

    Stupid? Absolutely!

    Probably misinformed for the lack of a better definition. How many users actually read or look at the cPanel manual or for that matter, log into their billing account at their datacenter and overlook the little button "Request an IP address".
