The Netsukuku project is based on the very simple idea of exploiting the great potentiality of the wifi connectivity, making the PCs of wireless communities act as routers and handle together an ad-hoc network even bigger than the Internet.
Netsukuku is an ad-hoc network system designed to handle massive numbers of nodes with minimal consumption of CPU and memory resources. It can be used to build a world-wide distributed, fault-tolerant, anonymous, and censorship-immune network, fully independent from the Internet. Netsukuku does not rely upon any form of backbone router, internet service provider network, or any centralized system, although it may take advantage of existing systems of this nature to augment unity and connectivity of the existing Netsukuku network.
A new Netsukuku user needs do little more than install an antenna within range of other local nodes, linking themselves into the network, and run the Netsukuku software on their computer to take advantage of it. The number of interconnected nodes can grow endlessly. If a node is out of the range of any wifi signals, a “virtual tunnel” over their Internet connection will supply the missing radio link.
Over the Netsukuku network various primary distributed services are guaranteed. One of these is ANDNA (A Netsukuku Domain Name Architecture), which is the non hierarchical and decentralized system of hostname management used in the Netsukuku network. It fully replaces the DNS and any node can register up to 256 hostnames.
