ARIN's transfer log records a merger, acquisition or reorganization from Greenville Health System (ARIN) to Prisma Health (ARIN) on 2023-06-15 22:03 UTC. The registration changed hands; it is not a new allocation from ARIN. ARIN-Issued and ARIN's statistics don't show this change; only the transfer log records it.

Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it reserved on 2017-07-31 and assigned (dated 2017-08-01) on 2017-08-02. The tracker saw this range removed from registration on 2016-08-23 (AS511), so it appears to have been issued again from ARIN's pool.

ARIN-Issued
Remove AS511
Inventory
Part of the issuance reported the same day

ARIN's statistics show it reserved on 2017-07-31 and assigned (dated 2017-08-01) on 2017-08-02. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS511. The issuance is explained on that line.

Hold estimate
Estimated hold end 2017-02-23. Possible reissue candidate after this date; not confirmed available.

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it assigned (dated 2010-03-04) on 2016-08-22 and reserved on 2016-08-24. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed ASNs for 6 calendar months before reissuing them, so the estimated hold end is 2017-02-23. This does not confirm availability.

Hold estimate

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it allocated (dated 2005-03-09) on 2009-03-02 and not issued on 2009-03-04. (Until 2013-03-05, ARIN's statistics list only what's issued.) Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed ASNs for 6 calendar months before reissuing them, so the estimated hold end is 2009-09-03. This does not confirm availability.
