Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2026-10-09. Possible reissue candidate after this date; not confirmed available.
Removed from active registration. The tracker found it by comparing LACNIC's daily statistics. LACNIC's statistics show it assigned (dated 2017-11-30) on 2026-04-08 and reserved on 2026-04-09. Public sources do not distinguish a voluntary return, revocation, or reclamation. LACNIC holds returned, revoked and reclaimed IPv4 space for 6 calendar months before reissuing it, so the estimated hold end is 2026-10-09. This does not confirm availability.
