About this ASN.
AS12 is a legacy single-digit allocation registered under ARIN to New York University, and it remains a live, well-connected campus network. It announces the classic 128.122.0.0/16 (NYU-NET) block plus the 216.165.0.0/18 ranges (including 216.165.88.0/24 for NYU London) and IPv6 2607:f600::/32 — about 11 IPv4 prefixes and one IPv6 prefix, with six upstreams, ten peers, and a couple of downstreams. Transit comes from GTT (AS3257), Lumen/Level 3 (AS3356), and Zayo (AS6461), with additional connectivity via TIM/Telecom Italia, Consortium GARR, and COLT, plus regional peering with NYSERNet (AS3754). The ARIN ASN RegDate of 1984-07-05 is the registry date (the NYU-NET block 128.122.0.0/16 carries a 1986 RegDate). For triage this is a live R1 university network carrying benign academic traffic; note that NYU operates more than one ASN — US AS12 versus the RIPE-registered AS50811 (New York University Abu Dhabi, country AE) — so attribute by geography. No notable public abuse signal was found as of June 2026.
