ARIN charges a $100 USD annual fee for coverage of legacy resources under the terms of the Legacy Registration Services Agreement (Legacy RSA). Org IDs already paying annual ISP or end user fees do not pay an additional fee to receive Legacy RSA coverage. There is no initial registration fee for legacy applicants, unless a transfer is required.
The annual fee will be $100 USD until 2013, at which time ARIN's Board of Trustees may choose to raise the fee. This fee will be waived until 2013 if the legacy applicant returns at least one-fourth of the number resources covered by the Legacy RSA. ARIN will accept the return of any IPv4 address block
So if Nortel etc. stops paying their bill, will their class-A be returned to the free pool automatically?
