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 2020-06-24 and allocated (dated 2020-06-25) on 2020-06-26. The tracker saw this range released from hold on 2020-06-24 (208.95.4.0-208.95.7.255), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2020-06-24: Remove 208.95.4.0-208.95.7.255), so the before-and-after statistics may include it.

Part of the issuance reported the same day
ARIN's statistics show it reserved on 2020-06-24 and allocated (dated 2020-06-25) on 2020-06-26. ARIN removed its own pool record for this range as part of issuing it: the same report adds 208.95.4.0-208.95.7.255. The issuance is explained on that line. Another change to this range was reported the day before or after (2020-06-24: Remove 208.95.4.0-208.95.7.255), so the before-and-after statistics may include it.

ARIN-Issued lists it as "Remove", but ARIN's statistics show the same record before and after (reserved). Another change to this range was reported the day before or after (2020-06-25: Remove 208.95.4.0-208.95.7.255; 2020-06-25: Add 208.95.4.0-208.95.7.255), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2019-10-04. 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 2008-09-15) on 2019-08-04 and reserved on 2019-08-06. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv4 space for 60 days before reissuing it, so the estimated hold end is 2019-10-04. This does not confirm availability.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.
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.
