-Yggdrasil is an early-stage implementation of a fully end-to-end encrypted
-IPv6 network. It is lightweight, self-arranging, supported on multiple
-platforms and allows pretty much any IPv6-capable application to communicate
-securely with other Yggdrasil nodes.

-When enabled the Yggdrasil service creates a tun device with a unique IPv6 in
-the <literal>200::/8</literal> address space. This device and address can be
-used to communicate with all other connected nodes in the
-<literal>200::/7</literal> Yggdrasil network. Each Yggdrasil node can also
-route a subnet using the first half of its address with the eighth bit masked
-as a prefix, that is to say, within the <literal>300::/8</literal> space. This
-prefix may be announced to locally attached networks.

-Despite the normal distribution of nodes within the <literal>200::/8</literal>
-space, the addresses of connected nodes can be readily enumerated, unlike the
-the traditional global IPv6 network. For this reason, all open services on a
-node should be considered public, or the system firewall should be enabled.
