And even if networks were only getting an 8 bit slide, that's 256 trips
back to the RIR to get to their current allocations sizes (over 1000
years if they had to return once every 5 years). However, 12-16 bit
slides seem more common (perhaps John knows the exact slide ratio,
though I suspect many ISPs haven't really nailed down what they need in
v6 yet) and that can exceed 10 year allocation rates for some ISPs.
