Facilities & Services, IPv6
This page contains information on IPv6 deployment at CMS.
IPv6 Information
- IPv6 Introduction
- Stateless address auto-configuration, SLAAC, is enabled by default on Scientific Linux. If you use a static IPv6 address, you probably want to turn this off to avoid multiple addresses for your machine.
- dCache versions 2.13 and higher support IPv6 out of the box
- HEPiX IPv6 Working Group deployment documentation
- WLCG IPv6 Task Force twiki
- gfal2-util need IPv6 explicitly enabled, /etc/gfal2.d/gsiftp_plugin.conf line 26: "IPV6=true"
- WLCG is planning to become IPv6-only, not dual stack
- xrootd v3 is IPv4 only (used in very old CMSSW versions)
IPv6 Storage Status of Sites
Storage needs to become IPv6 accessible, i.e. SRM/gridftp and xrootd endpoints accessible from IPv6-only hosts.
