Hello Daniel,

The prefix is for enabling autoconfiguration of a full IPv6 address
(without hardcoding anything) for all nodes connecting to the network
and to the border-router.

the full IP is: <prefix>:<802.15.4 MAC address>.

You will set the prefix if you start the tunslip6 program.
(or you hard-code a prefix instead).

Best regards,
-- Joakim Eriksson, SICS
