Legacy RSA Availability Extended to 30 June 2010

Posted: Fri, 15 January 2010

The ARIN Board of Trustees has extended the availability of the Legacy RSA. Legacy number resource holders now have until 30 June 2010 to sign the Legacy RSA. Any organization or individual in the ARIN service region holding legacy Internet number resources not covered by any other registration services agreement with ARIN is invited to sign.  In light of the impending IPv4 depletion and to preserve flexibility for the community to set number resource policy, ARIN may not continue to offer the Legacy RSA past the June 30 deadline.
