M = million. Some RIPE NCC address space has EU as its country, meaning that the address space is used in more than one country. Small amounts of address space are given out by RIRs to entities in countries that aren't normally served by that RIR.

Note that the figures above just show new allocations and assingments during the specified period that's currently still assigned/allocated. Returned address space doesn't show up at all.
