Not announced

Last known operator Arizona State University. No prefixes for this AS number were observed in the RouteViews RIB.

Summary

// analyst note
Dormant/legacy ASN. RDAP top-level autnum events give allocated_date=1990-05-23 and last-changed=2009-04-23 (distinct from several nested entity/POC-level dates in the same record, which are decoys, not the ASN's own dates). Which ASU-affiliated ASN carries live traffic today (AS62600 vs AS2900) is unresolved between angles and left as an open conflict rather than asserted.
// security note
No notable public abuse signal found as of 2026-07-18 (Spamhaus ASN-DROP/SBL, NANOG archive searches) — search-scoped, not a live authoritative lookup.

About this ASN.

Updated  ·  Confidence: Medium  ·  14 sources  ·  How this page is checked

AS677 is a legacy autonomous system number registered under ARIN to Arizona State University that currently announces zero IPv4 and zero IPv6 prefixes, making it dormant in the global routing table despite carrying an active ARIN registration.

The ASN was allocated on 1990-05-23, per the RDAP autnum's top-level registration event, and its ARIN record last changed on 2009-04-23. It is named ASU-AS and sits under the university's University Technology Office / Network Communications group, based in Tempe, Arizona.

Sources disagree on which ASU-affiliated ASN now carries the university's live routed traffic. One angle points to AS62600 (Sun Corridor Network, Arizona Board of Regents) based on bgp.tools context; another points to AS2900 (Arizona Tri-University Network, allocated 1996). Neither claim is confirmed by an ASU first-party statement, so this remains an open question rather than a settled fact.

No PeeringDB entry exists for AS677 itself (peeringdb.com/asn/677 returns HTTP 404), so its network type and peering policy are unpublished. With zero live announcements, RPKI posture cannot be assessed — bgp.he.net shows 0 valid and 0 invalid originations, consistent with no active routes to validate.

Exposure
AS677 announces no prefixes today, so it presents no live routed attack surface; residual risk is limited to registry-contact hygiene rather than active routing.
Abuse signal
No notable public abuse signal found as of 2026-07-18 in Spamhaus ASN-DROP/SBL or NANOG archive searches — a search-engine-scoped null result, not a live authoritative Spamhaus/NANOG lookup.
Unrelated incident
A May 2026 data breach of the Instructure Canvas learning-management platform affected ASU students, but ASU attributed it to Instructure's own platform, not to ASU-managed network infrastructure or AS677.
Contact hygiene
Two of three ARIN POCs (WILKE342-ARIN, ZA106-ARIN) are marked unvalidated by ARIN since 2026-03-06 and 2024-02-29 respectively; only the administrative/technical contact Adrian Cepleanu is currently validated.
