The US website has the power of COICA up its sleeves and is exploiting it to their advantage. Their procedure is simple. Simply take control of the DNS entry of the website to take down. This has depicted how unsafe the current state of DNS is and to address problems like these, a new DNS protocol is being developed by a group of enthusiasts.
The project called the Dot-P2P was stated recently and is making fast progress. BitTorrent is an extremely helpful protocol for managing and keeping files synchronized across servers. The underlying technologies are being modified to work with a client to client or peer to peer basis. The system is a decentralized DNS that simply exchanges information from one client to another.
The new decentralized DNS service will also have its own TLD, the .p2p TND just like .com, .net and so on.
All domain registrations for .p2p will be managesd by the OpenNIC. The domain registration will be free. However, the the website owner should prove the ownership of that domain.
This complete decentralized DNS will be managed with an application running on each host machine using the information and forwarding it at the same time.
