AS286

Not announced

Last known operator KPN Eurorings B.V. (KPN International). No prefixes for this AS number were observed in the RouteViews RIB.

Summary

// analyst note
Legacy KPN International ASN now owned by GTT and folded into AS3257. RDAP remark 'AS286 is now owned by GTT'. As of 2026-06 AS286 self-originates no prefixes (RIPEstat empty, bgp.tools confirms); bgp.he.net counts are transit routes carried within GTT. allocated_date 2002-09-06 is the RIPE RDAP autnum top-level registration event (first-party RIR fact).
// security note
NEUTRAL/DATED: no notable public abuse signal attributable to AS286 found as of 2026-06-25; no Spamhaus ASN listing surfaced (CleanTalk shows incidental customer-IP spam).

About this ASN.

Updated  ·  Confidence: High  ·  11 sources  ·  How this page is checked

AS286 is a legacy RIPE-region autonomous system number originally operated by KPN Eurorings B.V., the international wholesale and carrier arm of the Dutch incumbent Koninklijke KPN N.V. Under the "KPN EuroRings" brand it ran a pan-European fiber backbone offering IP transit, IP-VPN, WAN, ATM, SDH, wavelength, and dedicated internet access to enterprise and carrier customers across roughly 21 countries. The key triage point for AS286 is a change of control: GTT Communications, Inc. (NYSE: GTT) completed its acquisition of KPN International on December 2, 2019, and AS286 was subsequently migrated into GTT's primary ASN, AS3257, with migration completed by mid-2021. The live RIPE RDAP autnum record reflects this — status active, registrant now GTT Communications Inc. (ORG-GCI2-RIPE), maintainer AS3257-NET-MNT, and an explicit remark "AS286 is now owned by GTT." As of June 2026 AS286 does not self-originate any prefixes: RIPEstat returns an empty announced-prefixes list and bgp.tools confirms it is absent from the active routing table as a self-originator. Prefix counts visible at bgp.he.net (~1,341 IPv4 / ~59 IPv6) reflect routes carried in transit within GTT's broader network rather than independent AS286 originations, and the RPKI posture of those carried routes is poor (mostly unsigned or ROA-invalid). During its active life AS286/KPN International was an early and active RPKI/ROV adopter — dropping RPKI-invalid routes from customers from 2018-10-01 and from peers from mid-2019 — and no notable public abuse signal attributable to AS286 was found.

Operator
KPN Eurorings B.V. (subsidiary of Koninklijke KPN N.V.; "KPN EuroRings" / KPN International); current registrant GTT Communications Inc. [Confirmed] — RIPE RDAP autnum/286, as286.net, gtt.net press releases
Country / RIR
Netherlands (origin); RIPE NCC (legacy; RIPE-NCC-LEGACY-MNT). Current registrant address is Neu-Isenburg, Germany (GTT EU HQ) [Confirmed] — RIPE RDAP autnum/286
Allocated
2002-09-06 (RIPE RDAP autnum top-level "registration" event; first-party RIR registry fact, recorded not nulled); last changed 2022-10-31 [Confirmed] — RIPE RDAP autnum/286 events[]
Org status
KPN Eurorings B.V. defunct as an independent operator — acquired by GTT Communications, Inc. (2019-12-02, ~€50M) and migrated into AS3257 by ~2021; RIPE record remains active under GTT [Confirmed] — gtt.net press releases, RIPE RDAP autnum/286

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal attributable to AS286 found as of 2026-06-25 — no Spamhaus SBL/XBL/PBL ASN listing surfaced; CleanTalk maintains a per-ASN page (incidental customer-IP spam, expected for a large network). The June 2019 China Telecom route leak affected KPN's domestic AS1136 as a victim, not AS286 as originator. Corporate KPN incidents (2011 Getronics CA breach, 2021-disclosed Huawei access finding, unconfirmed 2025 data-sale claim) are separate from AS286 routing

Network & routing

Network type
NSP / Tier-1 IP network (KPN EuroRings pan-European backbone); PeeringDB classifies the ASN as NSP. AS286 is now legacy/migrating into AS3257 [Confirmed] — peeringdb.com/asn/286, as286.net
Size
not self-originating today — 0 IPv4 prefixes and 0 IPv6 prefixes self-originated (RIPEstat announced-prefixes empty; bgp.tools confirms absent from the active table). ~1,341 IPv4 / ~59 IPv6 prefixes appear at bgp.he.net as transit/carried routes within GTT, not independent originations [Confirmed for self-originated 0; Likely for carried counts] — RIPEstat / bgp.tools / bgp.he.net (2026-06)
Routing/peering
historical policy was Selective/Restrictive (no prefixes more specific than /24 IPv4 / /48 IPv6; AS-set AS-KPN; peering@as286.net); ceased establishing new peerings on acquisition and redirected contacts to AS3257/GTT. Upstreams observed at bgp.he.net include AS3257, AS3356, AS6762, AS6453, AS1299, AS6461
[Likely] — as286.net routing/peering policy, peeringdb.com/asn/286, bgp.he.net/AS286
RPKI
AS286/KPN was an early ROV adopter — dropped RPKI-invalid routes from all customers from 2018-10-01 and from all peers from ~2019-06 [Confirmed]. Posture of routes now carried under AS286 is poor: only ~4 ROA-valid (3 IPv4 / 1 IPv6) against ~538 IPv4 + ~26 IPv6 ROA-invalid; much of the rest unsigned
[Likely] — as286.net routing-policy, bgp.he.net/AS286
Notable usage
KPN EuroRings (AS286) was KPN's international wholesale/carrier network providing IP transit, IP-VPN, WAN, ATM, SDH, and wavelength transport to multinational enterprise and carrier clients across ~21 European countries, partly built on assets from the post-KPNQwest reorganization. GTT acquired KPN International (completion 2019-12-02, ~€50M) adding 400+ enterprise/carrier clients; AS286 fully migrated into AS3257 by ~July 2021
[Confirmed] — as286.net, gtt.net press releases, SEC 20-F filing
Related ASNs
AS3257 (GTT; AS286's current parent / migration target); AS1136 (KPN's domestic Netherlands network, distinct) [Confirmed] — RIPE RDAP autnum/286, gtt.net
Analyst note
Encountered as a legacy KPN International ASN now owned by GTT and operationally folded into AS3257. WHOIS/RDAP resolves to GTT; live routing is carried under AS3257, with AS286 not self-originating. The allocated_date 2002-09-06 is the RIPE RDAP autnum top-level registration event — a first-party registry fact, recorded as-is.
