I hope I don't spark off a huge discussion on this :-) But having said that, I am looking for personal as well as professional opinions. This email is being posted to both RIPE-EOF and NANOG as the decision could be helpful to both parties, not just those in the RIPE region. Background: A many weeks ago, SAFE (http://www.ircnetops.org/smurf) to the decision not to release the IP addresses of smurf amplifiers, only the weekly statistics on smurf amplifiers in RIPE IP space as a whole. This was to partly protect the misconfigured networks from being abused at a time when they may not be able to fix the problem immediately. Now: A number of requests have been made for SAFE to release the AS number of unco-operative[1] large (x500+ reply) smurf amplifiers, so that ISP's can filter these people out more easily. Further requests have been made that the AS numbers for *all* large smurf amplifiers be released weekly. What are the different thoughts people have on this? Kindest regards, [1] = those who fail to close an open smurf amplifier by the third check. Checks are performed weekly. Notifications are emails to 'abuse', 'tech-c' and 'admin-c' contacts as listed in the RIPE WHOIS database. -- Avleen Vig Network Security Officer Smurf Amplifier Finding Executive: http://www.ircnetops.org/smurf
