The fraction of general internet traffic carried over IPv6 continues to grow rapidly. The transition of WLCG central and storage services to dual-stack IPv4/IPv6 is progressing well, thus enabling the use of IPv6-only CPU resources as agreed by the WLCG Management Board and presented by us at CHEP2016. By April 2018, all WLCG Tier-1 data centres should have provided access to their services over IPv6. The LHC experiments have requested all WLCG Tier-2 centres to provide dual-stack access to their storage by the end of LHC Run 2. This paper reviews the status of IPv6 deployment in WLCG.
