The Big Squeeze

From a single data point on my router, /24's currently account for 64% of
the routing table entries and for 65% of the flapping prefixes. /16's
account for 12% of the routing table entries, and 10% of the flapping
prefixes. It doesn't appear to me there is a significant difference
between flap behaivor of long prefixes and short prefixes. There are
more long prefixes than short prefixes. But as a group they both tend
to flap the same proportion of 2% of the routes within the group.

Sorry, I'm not convinced this is the case. There is not enough
empirical evidence.

Is there any empirical evidence to show otherwise? Id' be interested in
seeing it.
