To make this useful as "public unicast", you need to upgrade *everything* in the path between a device using 240/4 and "whatever it wants to talk to", because un-upgraded routers or firewalls will just drop your packets otherwise - so, if RIPE were to give out a subnet of 240/4, it would not be very useful for "Internet" usage. OTOH, if you're willing to upgrade your multi-million enterprise network to make sure all devices support 240/4, it's all under your own control and can be done. (Would I do it? No... anything old won't grow support for it, and anything *new* can do IPv6 for new deployments - on islands, with gateways in between, but incidentially that's the only way a 240/4 deployment could succeeed as well. But hey, not my career to bet on 240/4 being useful :-) ) Gert Doering -- NetMaster -- have you enabled IPv6 on something today...? SpaceNet AG Vorstand: Sebastian v.
