Yeah I was thinking of the age of the entry, which is why I responded, I really was thinking "that would be insane!!!". But equally a last look-up time means prefixes used more frequently due to background scatter and bots just aimless scanning looking for open telnet ports with no other genuine traffic can be favoured over more "useful" / "valuable" but less freqeuncy used prefixes - so either way I don't like that idea.
