New PA code + pseudorandom = not win #33

(IRC log)

10.32 pseudorandom does not seem to work that well with AA etc 10.33 given it has 128 candidates, and it is trying to pick random address from /64 that hits it.. 10.33 odds of a hit are 1/2^57 10.33 oryon: any idea how to fix that? ;) 10.34 I suspect same problem might crop up with also normal prefixes, if ISP gives e.g. /48 and you try to allocate a /64 10.35 odds of a pseudorandom hit are 1/2^(64-48-7) 10.35 hrm, that's just 1 in 512, not so bad

Hamming distance stuff fixes this one.
