Part of the issuance reported the same day
ARIN's statistics show it reserved on 2025-09-30 and allocated (dated 2025-10-01), available on 2025-10-02. ARIN removed its own pool record for this range as part of issuing it: the same report adds 199.241.36.0-199.241.39.255, 199.241.56.0-199.241.59.255. The issuance is explained on those lines. Another change to this range was reported the day before or after (2025-10-02: Add 199.241.40.0-199.241.43.255; 2025-10-02: Add 199.241.44.0-199.241.47.255; 2025-10-02: Add 199.241.48.0-199.241.51.255), so the before-and-after statistics may include it.
