Hello, as Marcel wrote before, i also think the step between category M and L is to big. The Charging Scheme 2011 said: LARGE € 4,100 I think € 3,500 for catecory L should be ok, because it is between category M and L in the Charging Scheme of 2011. At this moment we have to calculate the Charging Scheme from IPv4 allocations, and IPv4 is running out. This mean, in future all LIR´s cannot get any IPv4 in big blocks so that they can use the free space in his category for growing. By Jens Winter X-NCC-RegID: de.zexotek
