And to put things into perspective, now that the IANA have allocated the final 5, some RIR's are already considering setting their minimum and/or maximum allocations to LIR's at /22 in one case, and their minimum of /27 in other cases. Expect things to start getting interesting as these remaining /8's are allocated to end-users and LIR's alike. We are yet to stress our kit. Cheers, Mark.
