Hi Dave,

Yes it is. Address space that has previously been in use has a
reputation attached to it.

A spammer's space is less usable than, say, the space currently
employed by ARIN for its web site. It's heavily blacklisted and email
systems installed within it won't function properly for months or
years after the spammer vacates.

Similarly, a /24 within a /8 whose minimum allocation is published as
/24 is more likely to route correctly than a /24 within a /8 whose
minimum allocation is published as /22.

Regards,
Bill Herrin


ppmlでもやはりJPOPMでも議論になったように、SPAMMER跡地は欲しくないよね、という意見あり。
他には小さいプレフィックスの中の/24よりも大きいプレフィックスの中の/24の方がいいとも。
