AS559

AS559 is registered under RIPE NCC to Switch, the foundation that operates Switzerland's National Research and Education Network (NREN), commonly known by its network name SWITCHlan. Switch was established in 1987 by the Swiss Confederation and eight university cantons as a private non-profit foundation, and it connects Swiss universities and research institutions to each other and to the wider Internet. Beyond backbone connectivity, Switch runs SWITCHaai federated identity services, operates SWITCH-CERT (an established computer emergency response team serving Swiss higher education and select critical infrastructure since the mid-1990s), and participates actively in the GÉANT pan-European research-networking community. RIPE RDAP records the autnum's top-level registration event as 2002-09-04, which is corroborated independently by bgp.tools narrative text stating the ASN "was registered on September 4, 2002" — a first-party RIR fact recorded here rather than nulled. Routing-table snapshots disagree on exact prefix and peer counts between bgp.he.net and bgp.tools (a common discrepancy given differing collector methodology and snapshot timing), but both agree AS559 is a large, long-lived, actively peering European network with roughly a thousand observed peering sessions and five upstream transit relationships. Switch's own RDAP remarks additionally document a detailed Remote-Triggered-Black-Hole (RTBH) filtering scheme, naming AS3356 (Lumen/CenturyLink), AS1299 (Arelion/Telia), AS174 (Cogent), and GÉANT (AS20965/AS21320) as community-translation targets — first-party evidence of Switch's real-world transit and peer relationships. No notable public abuse signal was found for AS559 as of 2026-07-11.

Operator

Switch (legal/trade name "SWITCH"; historically "Swiss Academic and Research Network"), a private non-profit foundation established 1987 by the Swiss Confederation and eight university cantons [Confirmed] — https://www.switch.ch/en/about/

Allocated date

2002-09-04 (RIPE RDAP autnum TOP-LEVEL registration event, eventDate 2002-09-04T09:28:22Z); last changed 2026-04-20 [Confirmed, corroborated by two angles] — https://rdap.db.ripe.net/autnum/559, https://bgp.tools/as/559

Org status

active, well-regarded operator with confirmed NANOG and SWINOG community participation and MANRS-aligned routing-security practices; SWITCH-CERT processed roughly 2,500 abuse cases in 2024 [Confirmed] — https://seclists.org/nanog/2025/Nov/261, https://www.switch.ch/en/switch-cert-report

Website

https://www.switch.ch/ (network operations portal https://network.switch.ch/) [Confirmed] — https://www.switch.ch/en/about/

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-11 in Spamhaus DROP/ASN-DROP references, NANOG archives, or general threat-feed search; bgp.he.net flags a "announces bogons" routing-hygiene notation (not a confirmed abuse incident); AbuseIPDB's detail page returned HTTP 403 so a specific abuse score could not be retrieved

Network & routing

Network type

National Research and Education Network (NREN) for Switzerland; PeeringDB classifies it Educational/Research, European scope [Confirmed] — https://www.switch.ch/en/about/, https://www.peeringdb.com/net/240

Size / routing

sources disagree — bgp.he.net reports 173 IPv4 / 43 IPv6 prefixes, ~2,184,960 IPv4 addresses, 1,329 observed peers; bgp.tools reports 116 IPv4 / 9 IPv6 prefixes, ~1,028 peers. Treat as approximate, point-in-time BGP snapshots [Likely] — https://bgp.he.net/AS559, https://bgp.tools/as/559

AS rank / customer cone / RPKI posture

Unknown — not obtainable from the search snippets retrieved; would need a direct CAIDA ASRank or bgp.tools page fetch [Unknown]

Upstreams / peers

both routing sources agree on 5 upstream carriers (individual names not resolved from snippets); RIPE RDAP's own RTBH community-translation remarks name AS3356, AS1299, AS174, and AS20965/AS21320 (GÉANT) as transit/peer-propagation targets, a first-party corroboration [Likely, partially Confirmed via RDAP remarks] — https://rdap.db.ripe.net/autnum/559, https://bgp.he.net/AS559, https://bgp.tools/as/559

IX / peering presence

CIXP (Geneva), Equinix Zurich, SwissIX (Zurich), AMS-IX, DE-CIX, plus Swiss university PoPs [Confirmed] — https://rdap.db.ripe.net/autnum/559

Peering policy

Selective — published policy evaluates prospective peers on mutual benefit, requires RIPE/Merit IRR registration (AS-SWITCH), BGP-4, no third-party transit, aggregated announcements only, and 24/7 or office-hours technical contact [Confirmed] — https://network.switch.ch/pub/peering-policy/

Notable usage
