We need to think about how IPs are allocated, a constant sticky problem in mesh networks. reseaucitoyen.be are suggesting to use IPv6 with the nodes' MAC addresses as a base, with tunnels for inter-mesh communication. The non-MAC part of the address remains to determine obviously...

Freifunk have been using unallocated IP space. Opennet has been using 192.168.0.0/16.

So far, i've been using 10.0.0.0/8, but we should really look at ipv6. See also http://wiki.freifunk.net/6mesh.freifunk.net.

Update: done, see ip for configuration et numbering for policy and allocation.
