The graphs below record, on a weekly basis (every Thursday at 16:00 CET) the fraction of endpoints listed in the CERN central BDII (lcg-bdii.cern.ch) where the DNS returns an IPv4-only (A) resolution (orange line), a dual-stack IPv6-IPv4 (A+AAAA) resolution (green line) or an IPv6-only resolution (blue line). The graph is meant to provide a bird's eye view of the IPv6 transition at WLCG sites.
