AS14

AS14 is a legacy single-digit allocation registered under ARIN to Columbia University in New York, and it remains a live campus network. Under the COLUMBIA-GW handle it announces the historic 128.59.0.0/16 block plus IPv6 — about 11 IPv4 prefixes and one IPv6 prefix — taking transit from Cogent (AS174) with roughly four peers. The ARIN record shows a blank ASN RegDate (only an "Updated 2010-06-28" timestamp), so the original 1984-era assignment date is not exposed by the current registry and is recorded as unknown rather than guessed. For triage this is a live academic network carrying benign traffic; the blank RegDate is a registry-refresh artifact, not evidence of inactivity. Note that AS47065 (the USC/UFMG PEERING research testbed) is hosted partly at Columbia but is a distinct ASN, not AS14. No notable public abuse signal was found as of June 2026.
