        Longer term plans to remove IPv4 from LHCOPN and LHCONE

        Discussion

        Remove IPv4 from all remaining LHCOPN links - end of 2026, before DC27

        Then discuss plans for LHCONE.
        We aim to stop using IPv4 for WLCG data transfers on LHCONE before DC29 in time to test for start of HL LHC Run4.

        How would we (the WG) like to see this happen?
        Remove IPv4 peering?
        Or just stop using IPv4 on LHCONE data transfers?

        Not our decision - WLCG MB, Experiments, LHCONE community, etc ....
