What's to stop spammers from doing this to cycle through blocks in rapid-fashion? This proposal seems easily abusable to me. - S ________________________________________ From: Peter Beckman [beckman () angryox com] Sent: Tuesday, September 08, 2009 10:04 PM To: Tom Pipes Cc: nanog () nanog org Subject: Re: Repeated Blacklisting / IP reputation How about a trial period from ARIN? You get your IP block, and you get 30 days to determine if it is "clean" or not. Do some testing, check the blacklists, do some magic to see if there are network-specific blacklists that might prevent your customers from sending or receiving email/web/other connections with that new IP block. If there are problems, go back to ARIN and show them your work and if they can verify your work (or are simply lazy) you get a different block. ARIN puts the block into another quiet period. Maybe they use the work you did to clean up the block, maybe they don't. Cleaning up a block of IPs previously used by shady characters has a real cost, both in time and money. The argument as I see it is who bears the responsibility and cost of that cleanup.
