ARIN's transfer log records a merger, acquisition or reorganization from GTT (ARIN) to GTT Americas, LLC (ARIN) on 2025-05-07 14:08 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.

2012-10-08ARIN+ AddApparent reissuance of previously removed resourceStrong inference
No transfer record matches. ARIN's statistics show it not issued on 2012-10-07 and allocated (dated 2012-10-08) on 2012-10-09. (Until 2013-03-05, ARIN's statistics list only what's issued.) The tracker saw this range released from hold on 2012-09-28 (2607:7F00::-2607:7F00:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF), so it appears to have been issued again from ARIN's pool.

Classification history for this change (4 versions)
ARIN-Issued says "Remove", but ARIN's statistics show it not issued on 2012-09-27 and not issued on 2012-09-29. (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 2012-11-30. 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 allocated (dated 2012-05-21) on 2012-05-29 and not issued on 2012-05-31. (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 IPv6 space for 6 calendar months before reissuing it, so the estimated hold end is 2012-11-30. This does not confirm availability.

2012-05-21ARIN+ AddApparent new issuanceStrong inference
No transfer record matches. ARIN's statistics show it not issued on 2012-05-20 and allocated (dated 2012-05-21) on 2012-05-22. (Until 2013-03-05, ARIN's statistics list only what's issued.) It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv6 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.
