States:
- Incomplete — Address Resolution is in process. The neighbor has not yet responded.
- Reachable — Neighbor is known to be reachable.
- Stale — Previously-known neighbor is no longer reachable. No action is taken to verify its reachability until traffic must be sent.
- Delay — Previously-known neighbor is no longer reachable. The interface is in Delay state for a predefined Delay Time. If no reachability confirmation is received, the state changes to Probe.
- Probe — Neighbor is no longer known to be reachable and Unicast Neighbor Solicitation probes are being sent to verify reachability.

The part of the IPv6 address space set aside for unicast addresses is structured into an address format that uses the first 48 bits for the routing prefix (like a network ID), the next 16 bits for a subnet ID, and the final 64 bits for an interface ID (like a host ID).

FAQ
Can't ping link-local
ping -6: Invalid argument
or
Destination unreachable: Address unreachable
append "%eth0" or whatever interface name to the address
