IPv6 RIPEness - The List of 4-star LIRs

Following up from the IPv6 RIPEness graphs we published earlier, those Local Internet Registries (LIRs) that fulfill all 4 IPv6 RIPEness criteria are now listed on the RIPE NCC web site.

After we initially started publishing IPv6 RIPEness information (as described in IPv6 RIPEness Update and Methodology ), we mentioned we would like to publish the list of '4-star LIRs'. After consulting with many of these LIRs we are now making the list of LIRs with 4-star IPv6 RIPEness publicly available:


This page is modeled after membership lists that were already published on http://www.ripe.net before.

To obtain this 4-star status an LIR has to:

  1. Get IPv6 address space from the RIPE NCC
  2. Have the address space visible in global routing
  3. Register a 'route6' object for this address space in the RIPE Database
  4. Have reverse DNS for this address space set up

For more information on the IPv6 RIPEness study, please see a list of all previously published articles and statistics related to that topic: http://labs.ripe.net/topics/ipv6ripeness

We hope that publishing this list, will provide an extra incentive for LIRs that have not taken steps to deploy IPv6 in their networks.

About the author

Emile Aben Based in Amsterdam, NL

I'm a system architect/research coordinator at the RIPE NCC, where I work in the science group. I'm a chemist by training, but have been working since 1998 on Internet related things, as a sysadmin, security consultant, web developer and researcher. I am interested in technology changes (like IPv6 deployment), Internet measurement, data analysis, data visualisation, sustainability and security. I'd like to bring research and operations closer together, ie. do research that is operationally relevant. When I'm not working I like to make music (electric guitar, bass and drums), do sports (swimming, (inline) skating, bouldering, soccer), and try to be a good parent.
