ARIN's transfer log records a merger, acquisition or reorganization from Telecom Evolutions, LLC (ARIN) to SYNDEO LLC (ARIN) on 2021-12-30 12:01 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.

Hold estimate
Estimated hold end 2020-11-23. Possible reissue candidate after this date; not confirmed available.

Removed from active registration. The tracker found it by comparing the RIPE NCC's daily statistics. The RIPE NCC's statistics show it assigned (dated 2000-12-29) on 2020-05-26 and not listed on 2020-05-27. Being gone from the RIPE NCC's statistics entirely can also mean it moved to another registry. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC holds returned, revoked and reclaimed IPv4 space for 180 days (six months), or longer while still routed, before reissuing it, so the estimated hold end is 2020-11-23. This does not confirm availability. Another change to this range was reported the day before or after (2020-05-26: Added 66.51.192.0/19), so the before-and-after statistics may include it.

2 transfer records from around 2020-05-27 cover parts of this IPv4 range, and none of them matches the range exactly, so the tracker doesn't pick one. Queued for review.

No transfer record matches. The RIPE NCC's statistics show it not listed on 2020-05-25 and assigned (dated 2000-12-29) on 2020-05-26. It wasn't in the RIPE NCC's statistics before, so it wasn't the RIPE NCC's unissued inventory; it may have come from another registry in a transfer not yet in the log.

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.
