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 IPV6 SE transfer test and state
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. Echo is now fully dual stack (as of Jan 2018). 2018-09-25 Success 16-Oct-2018
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.

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-SCOTGRID-GLASGOW Yes Yes Yes 2001:630:40:ef::0/64 Yes Yes Yes (left to join Phedex) Yes (DPM) Yes No No Initial introduction to IPv6 for production system, PerfSonar now dual stack, DNS and Reverse DNS confirmed to work and accessible via IPv6. 2018-10-9
UKI-SOUTHGRID-BHAM-HEP Yes Yes Yes 2001:630:1dc:1100::/56 Yes No No No No No No Have assigned gateway and perfSonar boxes IPv6 addresses and the both respond to ping. Waiting on IT to allow me to assign DNS entries to both to properly dual stack. 2018-24-05

(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

ADDITIONAL SECTION:

ns0.ic.ac.uk. 86400 IN A 155.198.142.80

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