The 41st Workshop of the DNS Operations, Analysis, and Research Center (DNS-OARC) held in Da Nang, Vietnam, brought together a diverse group of 115 attendees on-site, with many more joining remotely. The two-day hybrid event featured a series of insightful presentations that covered a wide range of topics, from insightful research into the inner workings of the DNS protocol to operational and security aspects of the Domain Name System.
Despite the challenges of long-distance travel, monsoons, and canceled flights, attendees had a memorable time in the idyllic setting of the Melia Da Nang Resort, where the warm and picturesque scenery provided the perfect backdrop for networking and knowledge exchange. OARC 41 was somewhat unlike previous OARC events: sunrise strolls, social dinners on the beachfront, and poolside discussions create a unique and enjoyable experience for participants to engage and network with their peers.
Participants can still fill out the OARC 41 Survey for a chance to win a 3-D Printer, the drawing was originally to be drawn on September 28, 2023, but has been extended to October 1st — so get your responses in ASAP.
The event included a wonderful dinner of local fare in Hoi An on September 5, adding a delightful cultural touch to an already enriching workshop. OARC 41, hosted by the Vietnam Internet Network Information Center (VNNIC) and co-located with the ICANN DNS Symposium, successfully fostered innovation and advancements in DNS security and infrastructure, reaffirming its importance for DNS professionals and experts worldwide.
