Transferred into RIPE NCC administration; not a new issuance

The RIPE NCC's transfer log records a transfer from an unnamed organization (APNIC) to Zappie Host LLC (RIPE NCC) on 2025-01-21 19:00 UTC: it came to the RIPE NCC from APNIC. It was already issued by another registry, so this is not a new issuance.

Inventory
Likely issued from APNIC-controlled inventory

No transfer record matches. APNIC's statistics show it available on 2011-04-07 and allocated (dated 2011-04-07) on 2011-04-08. The tracker saw this range removed from registration on 2010-12-21 (202.50.52.0/22), so it appears to have been issued again from APNIC's pool.

Inventory
Possible future reissue candidate after hold

Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 1995-04-21) on 2010-12-21 and not listed on 2010-12-22. Being gone from APNIC's statistics entirely can also mean it moved to another registry. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, and its statistics show a steady one (a year) only for removals from 2014-07-01 on; this one came earlier, so the tracker gives no estimate. 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.
