ARIN's transfer log records a merger, acquisition or reorganization from VANDHAM SECURITIES CORP (ARIN) to Wall Street Access (ARIN) on 2019-07-31 20:24 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.

No transfer record matches. ARIN's statistics show it reserved on 2014-11-30 and assigned (dated 2014-12-01) on 2014-12-02. The tracker saw this range released from hold on 2012-04-20 (192.73.45.0-192.73.45.255), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2014-11-30 and assigned (dated 2014-12-01) on 2014-12-02. ARIN removed its own pool record for this range as part of issuing it: the same report adds 192.73.45.0-192.73.45.255. The issuance is explained on that line.

ARIN-Issued says "Remove", but ARIN's statistics show it not issued on 2012-04-19 and not issued on 2012-04-21. (Until 2013-03-05, ARIN's statistics list only what's issued.) The registry's pool records from that time aren't public, so the tracker can't tell what was removed.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2011-12-19. 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 1990-07-18) on 2011-10-19 and not issued on 2011-10-21. (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 IPv4 space for 60 days before reissuing it, so the estimated hold end is 2011-12-19. 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.
