ARIN's transfer log records a merger, acquisition or reorganization from PRIME CARE TECHNOLOGIES, INC. (ARIN) to DAS Health (ARIN) on 2026-09-30 20:10 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 2020-02-12 and assigned (dated 2020-02-13) on 2020-02-14. The tracker saw this range removed from registration on 2019-10-07 (AS11476), so it appears to have been issued again from ARIN's pool.

ARIN-Issued
Remove AS11476
Inventory
Part of the issuance reported the same day

ARIN's statistics show it reserved on 2020-02-12 and assigned (dated 2020-02-13) on 2020-02-14. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS11476. The issuance is explained on that line.

Hold estimate
Estimated hold end 2020-04-07. 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 2011-05-18) on 2019-10-06 and reserved on 2019-10-08. 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 2020-04-07. This does not confirm availability.

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 2000-04-12) on 2010-11-01 and not issued on 2010-11-03. (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 2011-05-02. This does not confirm availability.

RDAP lookups

Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
