Consultation - New Legacy Registration Services Agreement (LRSA 3.0)

Posted: Wed, 05 October 2011

Based on executing approximately 500+ Legacy Registration Services Agreements (LRSA) and the corresponding feedback, ARIN has constructed a new LRSA, version 3.0, and is seeking community input regarding this new version.

Like prior LRSA versions, the LRSA 3.0 will be offered to those organizations and individuals in the ARIN service region who hold legacy Internet number resources not covered by any other registration services agreement with ARIN.  Existing LRSA holders are not impacted by the new 3.0 version, but may want to evaluate this new version for the benefits it could offer their organizations.

There are notable and substantive changes with this new version. These changes are highlighted in the change summary provided below with the new LRSA 3.0 available at the following URLs:
