Site Discussed with local networking team Asked for some IPv6 addresses Has IPv6 addresses IPv6 allocation IPv6 enabled hosts (1) IPv6 hostnames resolvable via IPv6 (2) Joined HEPIX gridftp testbed (no longer relevant) Joined HEPIX phedex testbed (no longer relevant) Dual-stack perfSONAR host Dual-stack worker nodes Dual-stack grid services (e.g. xrootd, SRM, gridftp) Notes Date last reviewed or updated
RAL Tier-1 Yes Yes Yes 2001:630:58::/48 Yes Yes No No Yes No Yes Dual stack, Squids, perfSonar, FTS, CVMFS Stratum 1 and CMS UK XRootD redirector. A test gateway is also dual stack for Echo. We intend to upgrade all the production gateways to Echo in Jan 2018. 2017-11-15
UKI-LT2-Brunel Yes Yes Yes ::/64 Yes Yes Not anymore Yes (DPM) No Yes Yes All services are dual stack, including in production: Args, DPM storage, Centos7 BDII, CEs (Arc/HTC) and all worker nodes. We have an experimental pure Ipv6 node.

UKI-LT2-IC-HEP Yes Yes Yes ::/64 Yes Yes No No No Yes Yes Most services dual-stack including dCache 2017-11-07
UKI-LT2-QMUL Yes Yes Yes 2a01:56c0:4033::/48 (for grid cluster) Yes No No Yes (Storm) Yes two nodes in test with NAT64 Yes dual-stack VLAN which also does jumbo frames. RIPE atlas probe, perfsonar and all grid services (CEs, SEs, xrootd, bdii, argus, squid) available via dual stack. 2017-11-07
UKI-LT2-RHUL Yes Yes Yes 2001:630:113:3::/48 No No No Working on dual stack perfsonar, IT stuck with IPv6 DNS lookup. 2018-02-06
UKI-LT2-UCL-HEP Yes No No No No No Central IT IPv6 project still in early stages.

UKI-NORTHGRID-LANCS-HEP Yes Yes Yes Yes, some Yes No No Yes No No Some odd routing issues with border router, but main obstacle to IPv6 deployment is network admin time. 2017-09-13
UKI-NORTHGRID-LIV-HEP Yes Yes Yes 2001:630:21:8d80::/64 Yes No No No Yes No No Addresses used on perfsonar systems; further ipv6 progress planned now our cluster room move is complete, but presently we have low bandwidth. 2017-10-31
UKI-NORTHGRID-MAN-HEP Yes Yes Yes 2001:630:22:1004::/64 Yes Yes (but no reverse lookup yet) No No Yes No Yes The IPv6 subnet may or may not change in the future. Services on IPv6: testbed CREAM CE, IPv6 only GridPP VOMS daemon (voms6.gridpp.ac.uk) 2017-11-07
UKI-NORTHGRID-SHEF-HEP Yes Yes Yes curently not available No No No No No ipv6 is currently unavailable (but it was available). The University does not currently run ipv6 due to hardware/software limitations on current border routers. Border routers expected to be replaced sometime within next 5 years. 2017-09-13
UKI-SCOTGRID-DURHAM Yes Yes Yes 2001:630:a5:1200::0/64 Yes Yes (but no reverse yet) Yes Yes Waiting for delegation of ipv6 reverse DNS before we can enable services 2015-07-28
UKI-SCOTGRID-ECDF Yes Yes Yes 2001:630:3c1:638::d545,d546 Yes Yes No No Yes No No

Recently worked with our university network team on testing IPv6 allocation, enabling dual-stack perfsonar hosts and checking bi-directional resolvability. As part of the testing work the network team have set up a script to send me a daily digest of connections to my IPv6 enabled hosts to assist with troubleshooting. Some issues with perfsonar tests still to be resolved. Next step is enable IPv6 on new middleware service instances.


UKI-SCOTGRID-GLASGOW Yes Yes Yes ::/64 Yes No Yes (left to join Phedex) Yes (DPM) Following campus planning. 2017-9-14
UKI-SOUTHGRID-BHAM-HEP Yes Yes No No No No Going to have another go at requesting addresses from Uni IT in the next couple of weeks. 2017-11-06
UKI-SOUTHGRID-BRIS Yes Yes Yes 2001:630:e4:2810::/64 2001:630:e4:2811::/64 Yes Yes No No No Yes Yes IPv6 enabled on WNs. XrootD access fails if WN's IPv6 is not added to DNS or /etc/hosts. 2017-11-06
UKI-SOUTHGRID-CAM-HEP Yes Yes Yes 2001:630:212:e10::/64 No No No No Limited manpower at site. Concern about impact on rest of local network. University ready to enable IPv6 on our network at any time. 2017-10-31
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. 2017-11-06




No No No Waiting for the completion of the RAL Tier 1 deployment, to learn the lessons from there before planning our rollout. 2017-09-13
UKI-SOUTHGRID-SUSX Yes Yes No No No No No No No No Currently no IPV6 at Sussex as Network team focusing effort elsewhere. We plan for dual stack on Grid components by Summer 2018 with wider rollout across campus as part of network upgrade in 2018/9. 2017-09-13

(1) Hosts with AAAA records exist in the public DNS, e.g.

dig AAAA netmon00.grid.hep.ph.ic.ac.uk


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


ns0.ic.ac.uk. 86400 IN A

ns0.ic.ac.uk. 300 IN AAAA 2001:630:12:600:1::80
