Adding more specifics of a /8, /16, or /24 prefix seems to have a disproportionate impact; my guess is it has something to do with the data structure used to store the prefixes. (If they use a 256-way mtrie like they do for CEF, more specifics of a /8, /16, or /24 would require creation of an additional internal node.)
Good point. I'd made the simple assumption that scanner spikes were due to table churn, as when redistributing connected and/or static routes to unstable interfaces. It happens that most such will be... unnaturally specific. [...] Peter E. Fry
