Good question.
For a better explanation I invite you to read the docs on the site.
Netsukuku uses a reactive protocol, and a path vector algorithm [1],
hence the data you need to "announce" and memorize for each
destination is even bigger. The key mechanism to reduce this data is
to use a hierarchical topology of the network. Nodes are grouped in a
so called g-node, g-nodes are grouped in g-g-nodes, and so on. In
analogy of IP classes of addresses.
So the real problem that netsukuku had to solve (we did it) is to
assign IP addresses that are consistent with this hierarchy and
dynamically react to changes in the topology.
