Hi RIPE-Atlas-users, one of the features often requested to add to RIPE Atlas is "enable IPv6 extension headers". We would like to know the details of your needs, so please join the discussion on the MAT-WG that Jens started: https://www.ripe.net/ripe/mail/archives/mat-wg/2013-November/000364.html (I am deliberately not copying the text here, please keep the discussion on one list...) Thank you for your input! Vesna
