AS60

AS60 is a legacy ARIN-region autonomous system number whose current registered holder is American Information Network (trading as AiNET), a commercial colocation, dark-fiber, and managed-services operator — a correction to any assumption that this very-low number is a university or government site. The official ARIN RDAP autnum name is "AINET-AS60" (confirmed live 2026-06-19); the "-PDFFILE" suffix that appears in RIPEstat and CAIDA holder fields is a known data artifact, not part of the registered name. AS60 was allocated on 1986-02-12 per the ARIN RDAP autnum top-level registration event (a first-party RIR fact, confirmed). Its history is more colorful: Potaroo's legacy-autnums mirror records the original RFC 1166-era label as "DARPA-BFLY — Advanced Info. Technology Services," a DARPA "Butterfly" gateway (the BBN Butterfly multiprocessor gateways used on the early DARPA/ARPANET research internet) — a research-internet origin entirely different from today's commercial holder. Routing status is confirmed dormant: RIPEstat routing-status shows 0 announced prefixes (0 of 327 v4 RIS peers and 0 of 323 v6 RIS peers seeing any routes) as of 2026-06-19, with last activity recorded on 2020-02-13 (prefix 138.204.116.0/22, first seen 2008-12-08). CAIDA corroborates: seen=false, degree 0 (no customers, peers, or providers), customer cone of 1 ASN / 0 prefixes / 0 addresses, AS rank 79,459. AiNET's active operational network runs under AS6405, which lists a Selective peering policy with presence at Baltimore IX and Global Peer Exchange. The org record lists American Information Network, OrgId AI, 11700 Montgomery Road, Beltsville, MD 20705, with NOC contact nc@ai.net / +1-888-324-6384. For triage, treat AS60 as a confirmed-dormant commercial-ISP legacy allocation originally issued for a DARPA research gateway. No notable public abuse signal was found as of June 2026.

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-19 — absent from Spamhaus ASN-DROP; no notations on Hurricane Electric BGP Toolkit, bgp.tools, or CleanTalk; no NANOG/threat-intel hits for AS60 or its sole historical prefix 138.204.116.0/22 — spamhaus.org/drop/asndrop.json, bgp.he.net/AS60, bgp.tools/as/60

Network & routing

Network type

NSP / commercial ISP — colocation, dark fiber, cloud, managed services; AS60 itself is a dormant legacy allocation, active network runs under AS6405 [Confirmed] — peeringdb.com/asn/6405, ai.net/about-us

Size

DORMANT — 0 IPv4 prefixes / 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses; last seen 2020-02-13 [Confirmed] — RIPEstat routing-status / CAIDA AS Rank (2026-06-19)

Routing/peering

CONFIRMED DORMANT — 0 announced prefixes (0/327 v4 RIS peers, 0/323 v6 RIS peers), CAIDA degree total 0 (customer 0, peer 0, provider 0), 0 observed neighbours, last activity 2020-02-13 [Confirmed]. AS60 PeeringDB record lists peering as "Open" (no ratio, no contract, 0 prefixes — consistent with dormancy); active family AS6405 lists "Selective" with Baltimore IX and Global Peer Exchange — RIPEstat / peeringdb.com/asn/60 / peeringdb.com/asn/6405

RPKI

not assessable — AS60 announces no prefixes, so there are no ROAs to validate (RIPEstat rpki-validation requires a prefix) [Unknown]

Notable usage

[historical] Potaroo legacy-autnums label "DARPA-BFLY — Advanced Info. Technology Services" (a DARPA "Butterfly"/BBN Butterfly multiprocessor gateway on the early research internet). [current] registered to American Information Network (AiNET); AiNET operates CyberNAP, a Tier IV data center in Glen Burnie, MD, and runs its active network under AS6405 — bgp.potaroo.net, ai.net/cybernap, peeringdb.com/asn/6405
