The graphs below record, on a weekly basis (every Thursday at 06:00 CET) the fraction of service endpoints listed in the VO Feeds of the 4 major LHC experiments (Alice, Atlas, CMS, LHC-B) where the DNS returns an IPv4-only (A) resolution (red line), a dual-stack IPv6-IPv4 (A+AAAA) resolution (green line) or an IPv6-only resolution (cyan line). The graph is meant to provide a bird's eye view of the IPv6 transition at WLCG sites.
