What's the use case for using IPv4?
Main reason for using IPv4 today is compatibility with existing devices. But with official IPv4 adresses becoming a scarce resource you end up with dozend and hundreds of 192.168.0.0, 172.16.0.0 and 10.0.0.0 networks which are horrible to interconnect. So one IPv6 subnet for every child should be the logical choice to use with OLPC. This way every child could use his OLPC to boot a broken OLPC of another child with an rescue system, without clashing with other OLPC in the area, as it is common with IPv4 if somebody accidently installs it's own DHCP server an hand out wrong IPs. Add an IPv6 to IPv4 Gateway to the 100$ Server and you end up with a system that should work quite well. cu andreas Christopher Blizzard <[EMAIL PROTECTED]> schrieb am 04.10.2006 02:23:24: > Any time you are unrouted, you have limited your system management > options. > > In this case, to the local island, forcing that any software repository > to also be local.
