AS192

AS192 is a legacy, low-numbered autonomous system number registered under ARIN to Rochester Institute of Technology (RIT), a private nonprofit research university founded in 1829 and headquartered at 103 Lomb Memorial Drive, Rochester, NY. Its first-party registry date is notably early: the ARIN RDAP autnum top-level registration event reads 1988-05-20, placing AS192 among the oldest ASNs ever issued, with the record last changed 2022-03-16. The key triage point for AS192 is that it is effectively dormant today. Every routing source consulted — RIPEstat routing-status, CAIDA AS Rank, and bgp.he.net — agrees it announces zero IPv4 and zero IPv6 prefixes, has zero visible BGP peers, zero upstreams, and zero customers. RIPEstat reports 0 of 327 IPv4 RIS peers and 0 of 323 IPv6 peers seeing it, and CAIDA places it at AS rank 79,459 with a singleton customer cone (the ASN itself, 0 prefixes, 0 addresses). RPKI posture cannot be assessed because there are no active originations and therefore no ROAs to validate. RIT's live operational routing instead runs under AS4385 (ROCHESTER-2), which announces 129.21.0.0/16, 192.77.9.0/24, and 2620:8d:8000::/48, peers at DE-CIX New York, and connects to Internet2 for research and education traffic. No notable public abuse signal was found as of June 2026 — not in Spamhaus ASN-DROP, FireHOL aggregated blocklists, AbuseIPDB, or NANOG archives — consistent with a clean, dormant ASN held by an accredited R&E operator that itself runs a recognized cybersecurity research institute.

Operator

Rochester Institute of Technology (private nonprofit research university; ARIN org handle RIT-3-Z, Rochester, NY) [Confirmed] — ARIN RDAP autnum/192, rit.edu

Country / RIR

US, ARIN [Confirmed] — ARIN RDAP autnum/192; RIPEstat abuse-contact-finder

Allocated

1988-05-20 (ARIN registry date from the autnum top-level registration event, NOT an IEEE date — IEEE publishes no ASN registration dates); last changed 2022-03-16 [Confirmed] — ARIN RDAP autnum top-level events (verified by direct fetch 2026-06-19, corroborated by angles A2 and A3)

AS name

ROCHINSTTECH [Confirmed] — ARIN RDAP autnum/192, bgp.he.net/AS192

Org status

active private nonprofit university (Rochester Institute of Technology), founded 1829; accredited by the Middle States Commission on Higher Education; Internet2 member [Confirmed] — rit.edu, msche.org/institution/0372

Contacts

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-18 — not in Spamhaus ASN-DROP, FireHOL aggregated blocklists, AbuseIPDB, or NANOG archives; dormant ASN under an accredited R&E operator that runs the ESL Global Cybersecurity Institute (NSA Center of Academic Excellence)

Network & routing

Network type

educational / research — private university campus network; AS192 is legacy/inactive (RIT's active network runs under AS4385) [Confirmed] — peeringdb.com/net/15680, rit.edu/its

Size

dormant — 0 IPv4 prefixes / 0 IPv4 addresses and 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses — RIPEstat routing-status / CAIDA AS Rank / bgp.he.net (2026-06)

Routing/peering

NOT announced — 0 RIS peers seeing it (0/327 v4, 0/323 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams or peers visible in any source [Confirmed]. RIT's active AS4385 runs an open peering policy with a contract requirement, peering at DE-CIX New York (IPv4 206.82.104.76, IPv6 2001:504:36::1121:0:1) [Likely for AS4385 policy, per PeeringDB]

RPKI

not assessable — AS192 announces no prefixes, so there are no ROAs to validate; RPKI validation skipped (no evaluable prefix) [Confirmed]

Notable usage

AS192 (ROCHINSTTECH / ROCHESTER-1) is an early/legacy RIT ASN that predates the institution's active AS4385 (ROCHESTER-2). AS4385 announces 129.21.0.0/16, 192.77.9.0/24, and 2620:8d:8000::/48, peers with ~28–33 BGP peers (Hurricane Electric, Cogent, GTT, NYSERNet) at DE-CIX New York, and connects to Internet2 — bgp.he.net/AS4385, peeringdb.com/net/15680

Analyst note

Encountered as a dormant legacy ASN registered to an accredited research university; WHOIS/RDAP resolves to RIT, but live routing is under AS4385, not AS192. The A1 raw fetch errored and captured only nested POC registration events (2002/2022); the authoritative autnum top-level registration date (1988-05-20) was confirmed by angles A2 and A3 and by a direct RDAP fetch. A5 abstained on the date due to a transient RDAP error — not a refutation. Clean, inactive ASN.
