Have you ever checked out the InvisiLAN technology? InvisiLAN is seemingly developed by ex-KGB and CIA directors. It's a random IP change technology inside LAN by a set of secureID like network cards and special router. Anarkey Network security, a Dutch company started to distribute InvisiLAN in Europe recently. I saw that they started "hacker's challenge 2003" to let hackers to break their invisible LAN security, however the news disappeared right away. I'm very curious about the technology. Are there someone who're knowledgeable about a security method to change randomly individual PC's IP?
