IPv6 WLCG Site Survey

This questionnaire is aimed at all WLCG Sites. Please add a row for your site to the end of the table below answering the questions. This information can be modified later if/when the situation changes (please change the date field at the same time).

Metadata

  • Site name in standard form
  • Date in ISO 8601 notation to allow easy sorting

Questions:

  1. Is your site already offering connectivity, routing and naming services for IPv6 end systems (i.e. is your site already connected to the worldwide IPv6 network and ready to support IPv6 end systems)?
  2. If so, have you already enabled IPv6 on some of the services you manage? Please provide details on which services are enabled
  3. If your site is not yet IPv6-ready, are there plans for this? If so, what are the timelines?
  4. Does your site currently have problems with allocating a sufficient number of IPv4 addresses? Or foreseen in the near future?
  5. Are there other issues you are aware of? Or interesting work going on in this area?
  6. Any other comments?

Answers by Site

Site Name Date when entered IPv6 connectivity IPv6 enabled services ETA for IPv6 readiness IPv4 exhaustion issues Other issues and related work Comments
NDGF 2014-05-12 Yes, but not to all of site For limited services, not main storage yet About one year No. Storage has plenty, a lot of worker nodes use private networks 3 out of 8 subsites are fully IPv6 connected, the rest are partially or IPv4 only
NERSC 2014-05-29 Yes. Some services yes but not all Some partially ready now (web, dns), the rest is scheduled for Q215 No
praguelcg2 2014-05-14 Yes. Many services yes but not all Partially ready now, the rest depends on service providers Yes
UKI-LT2-IC-HEP 2014-05-14 Yes Most services enabled but not dCache storage element Essentially ready now. Storage element should be ready when when dCache v2.9.0 goes into production No
UKI-LT2-QMUL 2014-05-14 Yes Perfsonar, RIPE Atlas probe, test SE Waiting for confidence that middleware won't break No. Worker nodes behind NAT. Sufficient IPv4 for world facing services (and University sees no risk of running out in the immediate future).
UKI-LT2-UCL-HEP 2014-05-14 No No Waiting for central IT to announce service, and middleware to be thoroughly tested No immediate shortage Central IT network division has set up IPv6 working group. I'm not up to date with their plans.
UKI-LT2-RHUL 2014-06-05 No No Under plan & discussion with network people No immediate shortage It is on Central IT do list after 10GB link.
UKI-LT2-Brunel 2014-05-14 Yes Perfsonar enabled. Experimental DPM storage enabled and passing Nagios tests. Only limitation to completely convert to dual-stack is DPM-xroot: No IPv6 version available. However, we have tested and jobs can run on dual stack nodes using IPv4 xroot. No
UKI-SOUTHGRID-CAM-HEP 2014-05-14 No No Service available from central IT, IPv6 addresses allocated. No immediate shortage Central IT enthusiastic about IPv6 deployment. Lack of manpower at site
UKI-NORTHGRID-LANCS-HEP 2014-06-05 To the institution, not the site. None. Early 2015, hope to have some IPv6 services by Q3 2014 We have enough for the next few years. Lack of manpower combined with little urgency makes IPv6 a low priority for our network admins, but they're engaging - it could be that we'll be their test case.
UKI-NORTHGRID-LIV-HEP 2014-05-14 We have new routers with IPv6 address that can ping IPv6 internet Not yet Planning in progress No immediate shortage Dedicating resource to core network with IPv6. Network team looks forward to offering IPv6 in the future.
UKI-NORTHGRID-SHEF-HEP 2014-05-28 No Not yet Planning in progress No immediate shortage
FNAL 2014-05-14 Yes, but limited web, email and services on IPv6 test network TBD No IPv4 exhaustion issues (yet) IPv6 and 100 Gb/s test networks are being combined
UKI-SCOTGRID-DURHAM 2014-05-15 No No No allocations have been finalised by Central IT None
UKI-SCOTGRID-GLASGOW 2014-06-04 Yes (test cluster) Yes (test cluster) Awaiting production IPv6 DNS on campus None
DE-KIT (GridKa) 2014-05-15 Yes, but still in the process of rolling out DNS, WEB,..., several projects are already deploying IPv6, Wirelss/WiFi is IPv6 enabled, number 43 at a top 242 list http://www.worldipv6launch.org/measurements/
IPv6 are arranged for a project an demand, general readyness available in approx. 1 to 2 years No IPv4 exhaustion forseable (at least not yet)
UKI-SOUTHGRID-OX-HEP 2014-05-16 Yes, but on a limited 'test' basis Dual stack site BDII, UI, and test CE, IPv6-only test DPM SE A University network upgrade is planned for late 2014, which should enable IPv6 as a normal production quality service The grid site has a /24 which is currently adequate, but with relatively little spare, and little to no prospect of getting more IPv4 space The main University routers cannot handle IPv6 in hardware so it is handled by dedicated (slow) boxes to avoid CPU load on the main ones. This limits the site's IPv6 bandwidth to <1Gbit/s
UKI-SOUTHGRID-SUSX 2014-05-28 no no no plans as yet, still to be discussed with university IT services The university has a /16 so no problems for IPv4 addresses

T2_FI_HIP 2014-05-28 Yes. httpd, sshd, bdii, CMS xrootd federator and perfsonar. New machines have IPv6 by default but not all services listen on IPv6. Waiting for confidence that middleware won't break

T2_US_Nebraska 2014-05-28 Yes xrootd, gridftp, SRM endpoints primarily though all Tier2 related machines have IPv6 addresses (just not necessarily AAAA records) Remaining issue is full DHCPv6/DNS support for all hosts to have proper DNS. Supplied via campus networking, should be within months. Yes in that we switched workers to public IPs but likely can't grow by an order of magnitude in this way Just the lack of full DHCPv6/DNS support from our campus

LRZ-LMU 2014-05-30 Yes None There are plans and things should be rather straight forward, but no schedule yet. For storage-nodes, we do not expect any shortcomming of IPv4 addresses anytime soon. I'm really pushing for this, but it's still a WIP.

UA-ISMA 2014-06-06 Yes No Before Q4 - 2014. No
NCP-LCG2 2014-06-06 To the institution, but not yet for the site. Few IT services are on Dual Stack like Web. Waiting for confidence about the middleware stability on IPv6. surely we will start migration very soon. Almost all available IPv4 pools are in use, so it will near to exhasut. No other issue as all Switches, Routers and Hardware are fully IPv6 supported.
Taiwan-LCG2 2014-06-06 Partially, the router should be available to forward ipv4/ipv6 dual stack, but it hasn't verified, because we don't actually have ipv6 service running in our DC None Deploying and testing dual stack ipv4/ipv6 network. No concrete schedule yet, but hope to enable ipv6 support by end of 2014, at meanwhile will also follow any decision that made by WLCG No, we still have at least two class-C available None
