v6 deagg

in a discussion with some fellow researchers, the subject of ipv6 deaggregation arose; will it be less or more than we see in ipv4? in http://archive.psg.com/jsac-deagg.pdf it was thought that multi-homing, traffic engineering, and the /24 pollution disease were the drivers. multi-homing seems to be increasing, while the other two were stable as a relative measure to total growth. so, at first blush, we thought v6 would be about the same as v4. but then we considered that v6 allocations seem to be /32s, and the longest propagating route seems to be /48, leaving 16 bits with which the deaggregators can play. while in v4 it was /24s out of a /19 or /20, four or five bits. this does not bode well. randy
