Hi all, we all know abuse-c data is to be filled by the IP assignee, which I call ISP in the following. I understand that, since ISPs own IP space it is their job to ensure that it isn't abused. If they give up the receiving of abuse complaints and give it to their customer instead, and they don't receive the complaints as a result, then they won't be aware if their customer is violating important policies. However, it is the ISPs' customers who are the effective users of those IPs. Any complaint, whether reporting spam or botnet activity, can probably be handled more effectively by the people who run the systems connected to a given IP than the actual owner. I propose that RIPE accepts abuse-c email addresses from verified effective users of a range of IP numbers, stores them in the database, and serves them in RDAP/ WHOIS queries besides the abuse-c addresses provided by the ISP. Various automated methods can be adopted to allow an effective user to be verified; for example publishing an HTTP URL or a DNS entry. Abuse contacts added that way can expire after a few months, forcing the effective user to renew them, so as to avoid stale entries. I'm unsure if the above requires proposing a new policy or what else. For the time being, it would be interesting to gauge if this WG likes the idea and if there are effective users, apart from me, who would be interested in publishing their abuse-c. Best Ale --
