The 24th DNS-OARC Workshop will take place in Buenos Aires, Argentina between March 31st and April 1st 2016, Thursday and Friday before IETF95. This will be the first time DNS-OARC is held in the Southern Hemisphere. To attract the best DNS minds and local audience, DNS-OARC is requesting proposals for presentations, with a preference for Operational Practices Reports, and "How we solved this problem" presentations. This workshop intends to build from previous strong DNS-OARC workshops, where both operational content and research are welcome. Presentations from DNS operators are particularly desired, as well as from DNS researchers. All DNS-related subjects are accepted. If you are an OARC member, and have a sensitive topic you would like to present for members-only, we will accommodate those talks too. A timeslot will be available for lightning talks (5-10 minutes) on April 1st, for which submissions will be accepted during March 31st on a first-come first-served basis.
