Uh, while the IPv6 routing table is not crouded, the amount of ("few")
deaggregated prefixes is actually somewhat unsettling - we see about
the same amount of prefixes announced "as allocated" and "more specific" -
about 4100 prefixes matching LIR allocations, and about 4000 being
"more specifics from LIR allocations", plus about 1200 "PI as assigned"
and 700 "more specific than assigned" (which might be due to aggregation
*in the assignment records* - like, 8 /48s given out, but documented as
a /45).

Further, the ratio between "exact match" and "more specific" has shifted
significantly in the last 18 months, from about 2:1 to about 1:1 now.

Numbers are here: http://www.space.net/~gert/RIPE/weekly/2012/29/ - pretty
far down the page, "Routing Table by Class of Prefix".
