About this ASN.

Updated  ·  Confidence: High  ·  3 sources  ·  How this page is checked

AS62 is a legacy 16-bit allocation whose current registered holder under ARIN is CyrusOne LLC (org CL-260), a data-center operator — not the Tektronix-associated "TEKVAXC" holder that RFC 1020 (1987) recorded for this number, so the famous historical label does not match the current holder. CyrusOne is a Dallas-based global data-center operator running more than 50 mission-critical facilities worldwide serving roughly 1,000 customers, including about 200 Fortune 1000 companies; it was taken private in March 2022 by funds managed by KKR and Global Infrastructure Partners in an approximately $15 billion all-cash transaction. AS62 is an actively used commercial backbone for that footprint: as of June 2026 it originates about 166 IPv4 and 10 IPv6 prefixes (~152,320 addresses), is observed with 104 BGP peers, and is present at five internet exchanges, with upstreams including GTT (AS3257), Lumen/Level 3 (AS3356), Cogent (AS174), Zayo (AS6461), and Hurricane Electric (AS6939). The ARIN ASN RegDate of 2012-09-28 is a registry-refresh/transfer date, not the original 1980s assignment. RPKI shows 0 valid originated prefixes (many IRR-valid). For triage this is a standard, actively-routed commercial data-center network. No notable public abuse signal was found as of June 2026.
