Description
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. More and more WLCG data transfers now take place over IPv6. During this year, the HEPiX IPv6 working group has not only been chasing and supporting the transition to dual-stack services, but has also been encouraging network monitoring providers to allow for filtering of plots by the IP protocol used. The dual-stack deployment does however result in a networking environment which is much more complex than when using just IPv6. Some services, e.g. the EOS storage system at CERN, are using IPv6-only for internal communication, where possible. The group is investigating the removal of the IPv4 protocol in more places. We will present our recent work and future plans.
