Initially we migrated just our storage head nodes to IPv6. This exposed problems with DPM. This was motivated by concerns by our site network team about the path that IPv6 packets left the university and the possibility that they wouldn't be directed through Janet. After being ticketed and discovering the problems with DPM in a mixed state we have reverted our roll out in production back to just IPv4. We have our test storage node and disk node dual stacked for testing and are currently engaged in conversations with our networking team as to when is best to dual-stack our production storage. This is ongoing due to staff holidays as well as a pending major networking intervention later in the year on the site. We have started speaking with the administrators who run the RDF facility about IPv6 and will update once it's clear what the restraints may be over doing this. |

| UKI-SOUTHGRID-OX-HEP | Yes | Yes | Yes | 2001:630:441:900::/56 | Yes | No | No | Yes | No | The IPv6 service from the University now runs on new hardware that supports it natively. However they do not provide DNS servies so we're only deploying test systems, no production work is being run over IPv6. Oxford Central IT Services team is looking into it | 2018-08-14 | |||

No | No | No | We've been having some issues with the initial test setup provided by RAL networking which was based upon a separate IPv6 VLAN, separately that type of setup has caused different (and more serious) issues at DESY so we have changed track. At the same time the planning for RAL to join LHCOne has simplified the setup we need for our Data Transfer Zone. So on 2018-10-30 the IPv6 gateway will be moved from it's dedicated VLAN onto the main IPv4 VLAN which will be the the DTZ after we join LHCOne.
The PerfSONAR node should already be available but we have been having issues with Router ACLs blocking access to it, but as part of the LHCOne migration planning we have agreement from ITSecurity to have the LHCOne DTA including IPv6 completely open and just relying on host firewalls. By 2018-11-07 PerfSONAR and CMS AAA xrootd gateways should be available by IPv6 By 2018-11-21 dCache Mover nodes (xrootd and gridftp) should be Dual Stack By 2018-11-28 dCache SRM should be Dual Stack By 2018-12-14 dCache Pool Nodes should be Dual Stack |

(1) Hosts with AAAA records exist in the public DNS, e.g.
dig AAAA netmon00.grid.hep.ph.ic.ac.uk
ANSWER SECTION:
netmon00.grid.hep.ph.ic.ac.uk. 300 IN AAAA 2001:630:12:580:207:43ff:fe11:ffb0
(2) Hostnames can be resolved from an external IPv6 only host, i.e. local DNS server has AAAA record, e.g.
dig netmon00.grid.hep.ph.ic.ac.uk
