About this ASN.

Updated  ·  Confidence: High

AS205 is a low-numbered, legacy autonomous system number registered under ARIN to Montclair State University, a public research university in Montclair, New Jersey (founded 1908; ~23,000 students; designated R2 doctoral and New Jersey's largest Hispanic-Serving Institution). The ASN handle is MONTCLAIR-AS, with the resource registered to the org handle MSU-6; the ARIN RDAP autnum top-level registration event is dated 1988-06-15, placing AS205 among the early university allocations from the pre-commercial Internet era. Today it is a small, stable stub network: routing sources (bgp.he.net, ipinfo.io) agree it originates the single legacy /16 130.68.0.0/16 (plus a more-specific 130.68.177.0/24), announces no IPv6, and reaches the wider Internet through two upstream/peer ASes — AS21976 (NJEDge.Net, the New Jersey statewide research-and-education consortium, itself an Internet2 connector) and AS46887 (Crown Castle Fiber / Zayo, commercial transit). PeeringDB lists the network but with all protocol fields unsupported, no IX memberships, and traffic data not disclosed, consistent with a single-institution eyeball/campus network rather than a transit provider. RPKI posture is effectively absent — bgp.he.net shows no valid ROAs and no invalids — and a bogon-announcement flag is noted there. No notable public abuse signal was found as of 2026-06-19: AS205 (130.68.0.0/16) does not surface on major threat-intelligence blocklists or in NANOG incident archives, and the security events touching the university in 2023 (MOVEit/National Student Clearinghouse) and 2026 (Canvas/Instructure breach) were third-party SaaS/vendor compromises, not outbound abuse from this network.

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-19 — not on Spamhaus DROP/SBL/XBL references, NANOG archives, or BGP hijack/route-leak databases. The 2023 MOVEit (National Student Clearinghouse vendor) and 2026 Canvas/Instructure breaches were third-party SaaS/vendor compromises, not abuse originating from AS205 [Confirmed; Likely for Spamhaus non-listing, inferred from absence — direct lookup HTTP 403] — bgp.tools/as/205, montclair.edu/newscenter/2023/08/14, en.wikipedia.org/wiki/2026_Canvas_data_breach

Network & routing

Network type
education — single-campus university (eyeball/stub) network for a public R2 research university [Confirmed] — ipinfo.io/AS205, montclair.edu/about
Size
small — 130.68.0.0/16 (~65,536 IPv4 addresses) plus the more-specific 130.68.177.0/24; 0 IPv6 prefixes announced [Confirmed] — bgp.he.net/AS205
Routing/peering
announces 2 IPv4 prefixes, 0 IPv6; 2 BGP peers/upstreams — AS21976 (NJEDge.Net, NJ R&E consortium, likely primary transit) and AS46887 (Crown Castle Fiber / Zayo, commercial transit); no IX memberships; no downstreams; avg AS path length ~4.96 [Confirmed for prefixes/peers; Likely for upstream designation] — bgp.he.net/AS205, ipinfo.io/AS205, bgp.tools/as/205
RPKI
no valid ROAs observed and no invalid origins — effectively no ROA coverage; bgp.he.net additionally flags a bogon-prefix announcement [Confirmed] — bgp.he.net/AS205
Peering policy
no public peering policy; PeeringDB entry exists but all protocol fields (Unicast IPv4, Multicast, IPv6, Route Servers) are unsupported and traffic/scope are Not Disclosed; last updated 2026-06-09 [Confirmed] — peeringdb.com/asn/205
Notable usage
campus wired/wireless connectivity for students, faculty, and staff; reaches the Internet2 research network via NJEDge; university IT runs enterprise servers, campus phone, and research-computing infrastructure [Confirmed for connectivity; Likely for Internet2 path] — montclair.edu/information-technology, archive.njedge.net, ipinfo.io/AS205
Analyst note
classic low-number legacy university ASN — long-running, small stub network with a single legacy /16, two upstreams, no IPv6, and no RPKI coverage; clean reputation. allocated_date taken from the autnum TOP-LEVEL registration event, not from nested POC/entity dates.
