I'm having a problem with a local competitor and need to get his IP address or possibly the range he is using so that I can exclude his IP/IPs from seeing my web site. I'm sure he is on a wireless network and should be able to take a laptop within range. How do I get this info? I've looked all over to see if there is software that will easily do this but have come up blank. Packet sniffing programs don't seem to do it either.
