Do we have any empirical research of this, i.e. can someone who uses
large chunks of v4 calculate a model that shows what the effect on
the routing table would have been if they'd had to apply for smaller
chunks of non-contiguous space more regularly ? Room to breathe in
your v4 allocations could have also encouraged sloppiness and
wastefulness. (Do we think all of - picking on some companies at
random - all of 9/8, 13/8, 15/8, 44/8, etc.,etc. are effective use of
A big routing table is bad, we all agree. Running out of v4 is
really really bad.
