I already have, but his IP changes all the time. Using a wildcard doesn't do it as the IP range allocated is too large.
That's why I want to find out all the possible IP addresses that the member can have, and ban them.
So it goes back to my original question:
Thanks.
How would I find out the IP address ranges that are leased to a particular ISP? I have a troublesome member who has a dynamic IP address, and I would like to ban all IP addresses that the member could possibly have from their ISP.
Thanks very much.
