The REAL Napster

I had a plan in place 7 years ago that would have prevented this very type of attack. It utilized dispersed local copies of DNS info at the client level and worked just like a P2P network. The whole idea of rootservers and DNS servers is a disaster waiting to happen and has been for years. Decentralize and you increase security and performance
