Autonomous system detail

AS299

Announced

Operated by UCINET-AS - University of California, Irvine.

Summary

// analyst note
Actively routed, single-homed university campus ASN (2 observed BGP neighbours). Clean abuse profile; hygiene gaps are absent RPKI ROAs and one unenumerated bogon flag. Upstream attribution to CENIC (AS2152/AS2153) is from third-party routing DBs, not first-party registry data.
// security note
NEUTRAL/DATED: no notable public abuse signal found as of 2026-06-27; absent from Spamhaus blocklists and CleanTalk top-300 (0.00% spam rate); no NANOG or hijack records.

About this ASN.

Updated  ·  Confidence: High

AS299 is a legacy autonomous system number registered under ARIN to the University of California, Irvine (UCI), a public research university founded in 1965 within the University of California system. The ASN, named UCINET-AS, carries the campus network (UCInet) operated by UCI's Office of Information Technology in Irvine, California. It is an actively routed education-and-research network rather than a commercial transit provider: ARIN RDAP lists the autnum as active, and RIPEstat announced-prefix timelines confirm it originates five IPv4 prefixes (128.195.0.0/16, 128.200.0.0/16, 160.87.0.0/16, 169.234.0.0/16, and 192.5.19.0/24, totalling roughly 262,400 addresses) plus one IPv6 prefix (2607:f538::/32). Upstream connectivity runs through CENIC (AS2152/AS2153), the Corporation for Education Network Initiatives in California, which provides CalREN backbone transit and onward Internet2 reach for UC campuses — consistent with the small observed BGP footprint of two neighbours typical of a single-homed campus stub. PeeringDB records an Open peering policy (last updated May 2023) with no public IX listings. The security posture is clean: AS299 is absent from Spamhaus blocklists and CleanTalk's abusive-ASN ranking (0.00% spam rate), with no NANOG incident threads or BGP-hijack records found as of June 2026. Two routing-hygiene notes stand out — bgp.he.net reports zero RPKI ROAs (prefixes are IRR-valid only) and flags a bogon announcement, most plausibly a router misconfiguration rather than abuse. A May 2026 Canvas LMS breach that touched UCI was an application-layer vendor compromise, not a network/BGP event on AS299.

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-27 — absent from Spamhaus blocklists and CleanTalk's top-300 abusive ASNs (0.00% spam rate); no NANOG threads or BGP-hijack records. bgp.he.net flags a bogon announcement (no incident corroboration; likely misconfiguration). A May 2026 Canvas LMS breach affected UCI but was a vendor application-layer compromise, NOT an AS299 network/BGP event [Confirmed for clean-feed status and Canvas scoping; Likely for blocklist absences] — cleantalk.org/blacklists/as299, bgp.he.net/AS299, oit.uci.edu/2026/05/09/update-canvas-nationwide-security-breach/

Network & routing

Network type
education / research — campus network (UCInet) for a public research university (UC system) [Confirmed] — uci.edu/about, bgpview.io/asn/299
Size
5 IPv4 prefixes / ~262,400 IPv4 addresses (4× /16 + 1× /24) and 1 IPv6 prefix (2607:f538::/32) [Confirmed for prefixes; Likely for address estimate] — RIPEstat announced-prefixes, bgp.he.net/AS299
Routing/peering
actively announced (RIPEstat prefix timelines continuous through 2026-06-26); 2 observed BGP neighbours, consistent with a single-homed campus stub; a routing-status snapshot at 2026-06-27 showed announced=false, likely a brief withdrawal or RIPEstat lag, not deactivation [Likely] — RIPEstat routing-status / announced-prefixes. PeeringDB policy Open (updated May 2023), no public IX listings
[Confirmed] — peeringdb.com/asn/299
Upstreams
CENIC (AS2152, AS2153) — CalREN/CENIC provides connectivity and onward Internet2 transit for UC campuses [Likely] — bgp.he.net/AS299, cenic.org/network
RPKI
no active ROAs — bgp.he.net shows 0 RPKI-valid originations across v4 and v6; all prefixes are IRR-valid only [Confirmed] — bgp.he.net/AS299
Notable usage
campus network (UCInet) serving UC Irvine — wired/wireless campus connectivity bridged to California's CalREN/CENIC research-and-education backbone for Internet2 access; UCI Health is also noted on this ASN [Confirmed] — uci.edu/about, oit.uci.edu/network/
Analyst note
Encountered as an actively routed, single-homed university campus ASN with a clean abuse profile; the only hygiene gaps are absent RPKI ROAs and a single unenumerated bogon flag. Upstream attribution to CENIC is from third-party routing DBs (bgp.he.net) rather than first-party registry data, hence [Likely].
