CKN23-ARIN Proposal Implemented

Posted: Wednesday, 15 November 2017

ARIN has completed the implementation of the plan that was developed in response to the CKN23-ARIN community consultation, which opened on 22 March 2017 and closed on 23 May 2017. This implementation plan was announced to the community on 6 September 2017. As a result, ARIN has performed the following work on 12,171 Organization Identifiers (Org IDs):

  • For the affected resource records, the Resource Points of Contact (POCs) that were in place as of
    29 June 2011 have been restored.
  • ARIN has removed CKN23-ARIN as the Admin and Tech POC on these Organization records and replaced it with the original resource POCs. 
  • The original resource POCs have been retained as the Abuse POCs on these Organization records. 
  • All Organization and Resource records affected have been locked, preventing the processing of any changes to the Organization and Resource records until the submitted changes have been reviewed and vetted by ARIN staff.
  • All requests for changes to the affected Organization and Resource records will need to be submitted in writing via an “Ask ARIN” ticket from within ARIN Online.

There are approximately nineteen thousand Org IDs in ARIN’s Whois that still have CKN23-ARIN (“No Contact Known”) as one of their POCs and will require further research in order to rectify. The following paragraphs provide additional details regarding the changes made (please note that these numbers will change over time): 

  • Approximately 750 Org IDs have direct assignments/allocations and are the result of the existing POC contacting ARIN to ask to be removed from the record as they were no longer associated with that organization. Because they were unable to provide a replacement POC, ARIN staff used CKN23-ARIN as a placeholder handle until a new POC could be added. These handles will require further research by ARIN staff.
  • Approximately 12,900 Org IDs have provider assigned assignments/allocations (they are associated only with reassignments made by an ISP). These Org IDs had no valid POCs associated with them. When policy proposal 2010-14 (NRPM 2.12) was implemented (requiring all Org IDs to have a Tech and Abuse POC), staff added CKN23-ARIN to these Org records in order to be in compliance with the policy. 
  • Approximately 6,200 Orgs have no assignments/allocations associated with them and are considered to be orphaned Orgs. These Orgs will be addressed in a future ARIN project.
