[anti-spam-wg@localhost] Proposal: list of unassigned IP space

[furio ercolessi <]

It now happens more and more frequently that spammers, or possibly
other abusers, hijack parts of IP space that nobody owns to carry on
abusive activities.   Sometimes it is space that has never been
assigned; sometimes space that was assigned in the past, then
withdrawn (no whois record); sometimes space that was assigned in 
the past, still looks assigned (whois record exists), but is no 
longer in use.

I was wondering whether there is a way to know, by automatic methods
and on a (say) daily basis, what are the IP blocks in the RIPE area
which are not assigned to anyone at present, as far as the registry
knows.  If not, I propose to make such a list available.  People could 
download it and use it to filter mail, or nullroute, or whatever.

Most problems of this kind are not in the RIPE area; but if RIPE
starts such a service, then this could help in getting the other
IP registries to do the same, and this could make the world a
better place ;-)
