AS886

AS886 is an active ARIN-region ASN, allocated 2022-06-07 and registered to the Collectivité de Saint-Barthélemy, that operates as the infrastructure ASN for SBH-IX, the Saint-Barth Internet Exchange. It is a small but live network: it announces exactly one IPv4 /24 and one IPv6 /36, both covered by valid RPKI ROAs, with no dormancy indicators.

SBH-IX launched on 2022-06-30 as part of the Caribbean Telecommunications Union's regional CaribIX initiative, alongside sister exchanges such as Saint Martin's SMART-IX. As of a May 2026 figure reported by CTU, SBH-IX carried 120 Gbps of cumulative member port speed with 11 ASNs listed in PeeringDB. Notably, AS886 itself does not appear on SBH-IX's own published member list — a separate ASN, AS396950 (also registered to the Collectivité), is listed there as a participant — which points to AS886 functioning as the exchange's own operational ASN rather than a customer-facing ISP number.

Routing sources place AS886's two BGP links (AS21351, Canal+ Telecom SAS, and AS396950, Collectivité de Saint-Barthélemy) as upstream/provider relationships per CAIDA and bgp.tools, though bgp.he.net labels the same two ASNs as peers — a source conflict that is not resolved here. BGP visibility is broad and mature (325/327 IPv4 and 319/321 IPv6 RIS peers), and CAIDA's customer cone is a singleton limited to AS886 itself. CAIDA's ASN geolocation places AS886 near Lyon, France, which conflicts with the RIR-registered Gustavia, Saint-Barthélemy address; this is flagged as an unresolved discrepancy rather than treated as the physical site.

A secondary ambiguity concerns the operator's canonical website: ARIN and PeeringDB list http://sbh-ix.fr, while a separately reachable bilingual site was found at sbh-ix.eservices-comstbarth.fr. Whether these are the same property under two hostnames, or two distinct sites, was not independently confirmed. Per the operator's own English page, SBH-IX is currently installed and temporarily managed by the Collectivité pending its formal establishment as an independent legal association.

Abuse signal

no notable public abuse, blocklist, or threat-feed entry found for AS886 as of an August 2026 search, including a check against the bountyyfi/bad-asn-list GitHub list — treated as a sourced absence, not a clearance.

Incident history

no NANOG mailing-list discussion and no documented BGP hijack, route-leak, or outage naming AS886 was found as of an August 2026 search.

RPKI posture

both of AS886's announced prefixes carry valid ROAs under origin AS886 (routinator validator), giving full ROA coverage for its current announcements.

Exposure

AS886's role as SBH-IX's own operational ASN, combined with the conflicting upstream-vs-peer classification between bgp.tools/CAIDA and bgp.he.net, means its two BGP relationships (AS21351, AS396950) warrant re-checking before being treated as simple transit.

Notable usage

operational ASN for SBH-IX, launched 2022-06-30 under the CTU's CaribIX project; SBH-IX reported 120 Gbps cumulative member port speed and 11 ASNs in PeeringDB as of a May 2026 CTU figure [Likely] — ctu.int, pch.net/ixp/details/2306

Related ASNs

AS396950 (Collectivité de Saint-Barthélemy; both an AS886 upstream and a separately listed SBH-IX member ASN); AS21351 (Canal+ Telecom SAS; AS886 upstream) [Confirmed] — CAIDA ASRank, bgp.tools, sbh-ix.eservices-comstbarth.fr/members.html

Analyst note

AS886 functions as SBH-IX's own operational ASN rather than a conventional customer-facing ISP number — it is absent from the exchange's published member list, where a different ASN (AS396950) represents the Collectivité as a member instead. Two unresolved discrepancies: (1) the operator's canonical website may be sbh-ix.fr or sbh-ix.eservices-comstbarth.fr, relationship unconfirmed; (2) CAIDA's geolocation (near Lyon, France) does not match the RIR-registered Saint-Barthélemy address. No MAC/OUI or IANA RFC claims apply to this ASN research.
