'''''ANDNA''''' (Abnormal Netsukuku Domain Name Anarchy) is the distributed, non hierarchical and decentralised system of
hostname management in [[Netsukuku]]. It substitutes the [[Domain Name System|DNS]].
The ANDNA database is scattered inside all Netsukuku network. In the
worst case, every node will have to use few hundred kilobytes of memory.

ANDNA works basically in the following way:
in order to resolve a hostname we just have to calculate its hash.
The hash is nothing more than a number and we consider this number as an ip
and the node related to that ip is called andna_hash_node.
Practically the hash_node will keep a small database, which associates all
the hostnames related to it with the ip of the node, which has registered
the same hostnames.

<pre>
Node n
ip: 123.123.123.123
hash( hostname: "netsukuku" ) == 11.22.33.44
||
||
Node i
ip: 11.22.33.44
{ [ Andna database of the node i ] }
{ hash("netsukuku") ---> 123.123.123.123 }
</pre>

The revocation requests don't exist, the hostname is automagically deleted when it isn't updated.

=== SNSD ===

ANDNA implents the [[SNSD (netsukuku)|Scattered Name Service Disgregation]], a system to register multiple IPs and hostnames to specific [[network service]]s.
