Hi, The damage potential of accepting "up to /29 from 3 distinct /8" is huge. Please remember that one single /8 can contain up to 2 millions /29. If today's count of "/25 up to /29" is still quite low, this would open the way to hell on transfer market (which is self-limiting to /24), with possibility to go into "portable adresses" land (like in phone number portability). In IPv6 land situation is even worse (let's just hope we won't reach the 200-300K v6 routes very soon). -- Radu-Adrian FEURDEAN fr.ccs
