AS378

AS378 is a low-numbered legacy autonomous system number registered in the RIPE database under the AS name MACHBA-AS to IUCC — the Israel Inter-University Computation Center (Hebrew: מחב״א / MACHBA), org handle ORG-IIIC1-RIPE, based at the MATACH building, 16 Klausner Street, Tel Aviv. IUCC is Israel's National Research and Education Network (NREN): a non-profit established in 1984 by Israel's research universities and supported by the Planning and Budgeting Committee of the Council for Higher Education. It operates ILAN, the backbone connecting the eight Israeli research universities and affiliated research institutes, with international reach into GEANT (the pan-European research network, AS20965/AS21320) and onward to Internet2. Unlike the dormant legacy ASNs common in this range, AS378 is actively routed: RIPEstat reports roughly 53 announced IPv4 prefixes and a single IPv6 prefix (2001:bf8::/32), about 1.16M IPv4 addresses, and CAIDA ranks it 7,696 with a small clique-connected customer cone (2 ASNs). Transit comes from GEANT; customers include Ashkelon College (AS41116) and Seminar Kibbutzim College (AS200309), and it peers at the Israel Internet Exchange (AS5585). RPKI hygiene is strong — bgp.he.net reports 53 of 55 originated prefixes ROA-valid with zero invalid. The abuse contact is cert@cert.ac.il, the Israeli academic CERT. No notable public abuse signal was found as of 2026-07-02 across Spamhaus, AbuseIPDB, and NANOG archives; the one routing-hygiene note is a bgp.he.net "announces bogons" flag, presented as an observation rather than a confirmed abuse incident.

Org status

non-profit established 1984 by Israel's research universities, supported by the Planning and Budgeting Committee of the Council for Higher Education; RIPE registration status LEGACY; specific Israeli amutah (non-profit registration) number not found [Confirmed for founding/status; Likely for LEGACY classification] — https://www.iucc.ac.il/en/about/, https://rdap.db.ripe.net/autnum/378

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-02 — nothing ASN- or org-specific in Spamhaus, AbuseIPDB, or NANOG archives; bgp.he.net shows an "AS378 announces bogons" routing-hygiene flag (no prefix/date detail retrievable — presented as an observation, not a confirmed abuse incident)

Network & routing

Network type

Educational/Research NREN (National Research and Education Network); operates ILAN, Israel's academic backbone; PeeringDB also classifies as Educational/Research [Confirmed] — https://www.iucc.ac.il/en/infrastructuretechnologies/networking/, https://www.peeringdb.com/net/22301

Size

actively routed — ~53 IPv4 prefixes, 1 IPv6 prefix (2001:bf8::/32), ~1,164,800 IPv4 addresses; CAIDA customer cone = 2 ASNs / 37 prefixes / ~1,165,056 addresses [Confirmed] — https://stat.ripe.net/AS378, CAIDA ASRank API (as-rank.caida.org, asn=378)

Routing/peering

CAIDA degree total 3 (customer 1, peer 0, provider 2; clique member = true); ~4 observed BGP neighbours per RIPEstat; upstreams via GEANT (AS20965 Europe, AS21320 VRF); peers at IIX/Israel IX (AS5585); customers Ashkelon College (AS41116) and Seminar Kibbutzim College (AS200309); default route via AS20965 [Confirmed for degree/cone; Likely for the qualitative upstream/peer/customer labels] — https://rdap.db.ripe.net/autnum/378, https://bgp.he.net/AS378, https://bgpview.io/asn/378, https://stat.ripe.net/AS378

Peering policy

PeeringDB (operator-submitted) lists "Open" with no ratio/contract/location requirements; peers at IIX Israel and IL-IX, facility presence at MedOne PT1, Petah Tikva; no standalone first-party policy document found on iucc.ac.il

RPKI

strong hygiene — bgp.he.net reports 53 of 55 originated prefixes (52 IPv4 + 1 IPv6) ROA-valid, 0 invalid [Confirmed]. A per-prefix RIPEstat rpki-validation pass was not run this cycle [Unknown for a per-prefix blanket verdict] — https://bgp.he.net/AS378

Notable usage

NREN backbone for the Israeli academic/research sector — connects all 8 Israeli research universities plus affiliated institutes via ILAN; international connectivity into GEANT and onward to Internet2; IUCC is a member of GEANT and PRACE

Analyst note

Encountered as an actively-routed legacy R&E ASN for Israel's NREN. Registry object created 2002 (RIPE DB), but the AS number itself is low/legacy; the 2002 date is the earliest first-party RIR event surfaced by RDAP and is recorded as allocated_date per the registry-fact rule. Search noise: "AS378" collides with an Alaska Airlines flight number, so queries needed ASN-specific qualifiers.
