Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2014-01-10. 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 2009-12-31) on 2013-11-10 and available on 2013-11-12. 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 2014-01-10. This does not confirm availability.

APNIC's transfer log records a transfer from WANGT (ARIN) to SunnyVision Limited (APNIC) on 2013-11-08 07:12 UTC: it came to APNIC from ARIN. It was already issued by another registry, so this is not a new issuance.

Hold estimate
Estimated hold end 2013-09-06. 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 2009-12-31) on 2013-07-07 and reserved on 2013-07-09. 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 2013-09-06. This does not confirm availability.

Add 174.138.144.0-174.138.159.255
Inventory
Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it not issued on 2009-12-30 and allocated (dated 2009-12-31) on 2010-01-01. (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.

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.
