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 Joined HEPIX phedex testbed Dual-stack perfSONAR host Dual-stack worker nodes Dual-stack grid services (e.g. xrootd, SRM, gridftp) Notes Date last updated
RAL Tier-1 Yes Yes Yes ::/64 Yes Yes No No No No No Working with vendors to fix problems on Tier1 core routers. So the rollout of IPv6 to production network is on hold. The testbed is functional 2015-07-22
UKI-LT2-Brunel Yes Yes Yes ::/64 Yes Yes Not anymore Yes (DPM) Yes Yes Yes IPv6 services in production: Storage, CEs (Cream and Arc/HTC)and all worker nodes 2015-04-21
UKI-LT2-IC-HEP Yes Yes Yes ::/64 Yes Yes Yes (but since left) Yes (Storm & DPM) Yes Yes Yes Most services dual-stack including dCache 2014-10-14
UKI-LT2-QMUL Yes Yes Yes 2a01:56c0:4033::/48 (for grid cluster) Yes No No Yes (Storm) Yes No Yes dual-stack VLAN which also does jumbo frames. RIPE atlas probe. DEV: cream (ce04, ce08), storm (se01, se02), xrootd(xrootd02). Prod: storm (se03, se04) 2015-07-21
UKI-LT2-RHUL Yes Not yet No No No No IT will look into after 10GB link commisioing in Sept14 2014-08-12
UKI-LT2-UCL-HEP Yes No No No No No Central IT IPv6 project still in early stages.

UKI-NORTHGRID-LANCS-HEP Yes Yes No No No No Some work progressing on this within the central services team (setting up IPv6 services, dns etc), need to re-engage with them 2015-07-28
UKI-NORTHGRID-LIV-HEP Yes Yes No No No No No Central Services have a new core network with IPv6 addresses. An old piece of kit needs bypassing to give us access to the new core. Once connected we should be able to start testing dual-stack on perfsonar. Target Autumn/Winter 2015. 2015-07-28
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) 2015-08-27
UKI-NORTHGRID-SHEF-HEP Yes Yes Yes 2001:630:63:3::41c5:101 Yes Yes No No Yes 2015-02-24
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 Testing Testing No No Testing No No

- Met with university network services in August to discuss plans and address allocation and testing strategy - Got the go ahead from ECDF to test IPv6 on our service VLAN (which is insulated from their cluster) - Have allocated IPv6 addresses to our two perfsonar hosts to check bi-direction resolvability before moving onto other middleware services


UKI-SCOTGRID-GLASGOW Yes Yes Yes ::/64 Yes No Yes (left to join Phedex) Yes (DPM) Building a dual stack test cluster. 2014-8-13
UKI-SOUTHGRID-BHAM-HEP Yes Yes No No No No Have requested IPv6 addresses from University central IT. Waiting to hear back. 2014-08-14
UKI-SOUTHGRID-BRIS Yes No No No No No University ready and willing - limited manpower at site 2014-08-13
UKI-SOUTHGRID-CAM-HEP Yes Yes Yes 2001:630:212:e10::/64 No No No No University ready and willing - limited manpower at site 2014-08-12
UKI-SOUTHGRID-OX-HEP Yes Yes Yes 2001:630:441:900::/56 Yes No No Yes Some The IPv6 service from the University runs on somewhat bandwidth limited and non-redundant kit, so we're only deploying test systems, no production work is being run over IPv6. We hope to change that rapidly once the University network upgrade completes. 20150728
UKI-SOUTHGRID-RALPP Yes No No No No No IPv6 Now enabled on Campus routers - Waiting for Central testing to finish before the make address spaces available to departments.
UKI-SOUTHGRID-SUSX Yes Yes No No No No New central University core routers installed in early summer 2015, which will enable IPv6 work to progress now. I need to chase them again as this was previously the hold up. 2015-07-28

(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
