That's like asking them to state the obvious...

Well, forcing a periodic renumbering whenever adress gets freed and
there's a potential agregation is a good thing. It should be stated in
service agreements, IMHO.

Unless many contiguous blocks are assigned as different objects : a
RBL must NOT presume of one end-user's inetnum unless it has been
cathed doing nasty things AND didn't comply to [email protected] requests.

But most RBL managers are shitheads anyway, so help them evade,
that'll be one more proof of spamhaus &co. uselessness and negative
impact on the Internet's best practices.
